Introduction
What is crude oil?
Crude oil is a naturally occurring flammable liquid that has a complex mixture of hydrocarbons of various
molecular weights and other liquid organic compounds found in geologic formations beneath the earth‘s
surface. This fossil fuel is formed when large quantities of dead organisms are buried under sedimentary
rocks and undergo transformation due to intense heat and pressure. Crude oil composition varies
significantly from one oil source to another; four different types of hydrocarbon molecules appear in
crude oil, and their percentages vary in different crude oil forms. Crude oil, which is usually found with
natural gas, is recovered through oil drilling.
Crude oil is refined and separated at the boiling point into a number of products, ranging from petrol (or
gasoline) and kerosene to asphalt and chemical reagents used to make plastics and pharmaceuticals. The
process through which crude oil is separated into its various by-products is known as cracking. Oil
refinery cracking processes enable production of ―light‖ products such as liquefied petroleum gas (LPG)
and gasoline from heavier crude oil distillation fractions such as gas oils and residues. Fluid catalytic
cracking produces a high yield of gasoline and LPG, while hydro cracking is a major source of jet fuel,
diesel, naphtha, and LPG. Thermal cracking is currently used to ―upgrade‖ very heavy fractions or
produce light fractions or distillates, burner fuel, and petroleum coke. Crude oil is used to manufacture a
wide variety of materials. The world consumes about 88 million barrels of oil per day (MMbbl/d).
Oil – Key Element of Global Energy Mix
Global energy consumption is divided into the following five segments: liquids (majorly oil), natural gas,
coal, nuclear energy, and others (including hydro, wind, and solar). Oil accounts for one-third of the
world‘s energy consumption and is expected to grow at a compound annual growth rate (CAGR) of 1%
between 2011 and 2035, with strong growth expected from emerging markets. By 2035, the share of oil
is expected to decline to 29%, due to strong growth in nuclear energy and other non-conventional
sources of energy. However, oil will continue to account for a sizeable portion of the global energy mix,
as there are challenges associated with producing other energy sources. For example, hydro power, wind
power, and solar power cannot be produced everywhere. Further, while some energy sources (e.g., fuel
cells) are yet to take off, others (e.g., coal reserves) are not present everywhere. There have been
increasing concerns about nuclear power, especially after the 2011 tsunami, which led to incidents of
nuclear radiation from the Fukushima power plant in Japan.

Largest Oil Producer: Middle East
Global crude oil production grew at a CAGR of 2.1% over 1965–11, with particularly strong growth in the
Asia-Pacific region (4.9%), followed by Africa (3.0%), the Middle East (2.6%), Europe and Eurasia
(2.5%), South and Central America (1.2 %), and North America (0.7%). In 2011, global crude oil
production was 83.6 MMbbl/d, of which the Organization of the Petroleum Exporting Countries (OPEC)
produced 35.8 MMbbl/d. By region, the Middle East is the largest producer of oil (33%), followed by
Europe and Eurasia (21%), North America (17%), Africa (10%), Asia-Pacific (10%), and Central and
South America (9%). By country, Saudi Arabia was the largest producer in 2011, with 11.2 MMbbl/d,
followed by Russia (10.3 MMbbl/d) and the US (7.8 MMbbl/d).
Largest Oil Consumer: Asia-Pacific
The increase in global crude oil consumption was driven by strong demand in Asia-Pacific (4.8%), the
Middle East (4.8%), Africa (4.1%), and South and Central America (3.0%). This growth in consumption
was also driven by the increasing pace of development in emerging markets. In 2011, global petroleum
consumption was 88.03 MMbbl/d, of which OECD alone consumed 45.9 MMbbl/d, or 52%. By region,
Asia-Pacific is the largest consumer of oil (32%), followed by North America (26%), Europe and Eurasia
(22%), the Middle East (9%), Central and South America (7%), and Africa (4%). By country, the three
largest consumers are the US (18.8 MMbbl/d), China (9.8 MMbbl/d), and Japan (4.4 MMbbl/d). Figures 3
to 10 show the production and demand patterns in the evolution of the oil industry, including the current
scenario.

Top Five Countries Account for 45% of Global Oil Production
In 2011, the world‘s five largest producers – Saudi Arabia, Russia, the US, Iran, and China – represented
nearly 45% of global oil production. Figure 11 provides global production statistics by country for the
year 2011. During the year, global oil production increased 1 MMbbl/d (1.3% y-o-y), with OPEC countries
recording majority growth, offsetting weak production from Libya. Output from countries such as Saudi
Arabia, the UAE, and Qatar reached a record high in 2011, while that from non-OPEC countries was
broadly flat. Among non-OPEC countries, production increased in the US (reaching its highest level since

production in the UK and Norway as well as unexpected outages in some other countries.
While global oil consumption increased 0.6 MMbbl/d in 2011, this was one of the weakest growth rates
among fossil fuels. China recorded maximum consumption growth in 2011, although the growth rate was
below its 10-year average.

Middle East Accounted for 48% of Global Oil Reserves in 2011
An oil reservoir includes both producible and non-producible oil, which together are referred to as oil in
place. Due to limitations in petroleum extraction technologies and reservoir characteristics, only a
fraction of this oil in place can be brought to the surface. This producible fraction is called the ―reserve‖.
These reserves are broadly classified into two categories – proven and unproven. Proven reserves are
those from which oil can be recovered using existing technology and under the current economic and
political environment. The remaining reserves are termed as unproven reserves. Unproven reserves are
further classified as probable and possible reserves. Probable reserves have a known accumulation of oil
and a 50% chance of recovery, while possible reserves are those with less possibilities of recovery.
Since 1980, the world‘s proved oil reserves have increased by more than 100%, with particularly strong
bases in South and Central America, followed by Africa and the Middle East. Over the past decade, there
has been a strong movement in the percentage of global proved reserves from the Middle East to South
and Central America, led by a few major findings in Venezuela. In 2011, total proved reserves amounted
to 1,652.6 billion barrels, of which nearly 48% were in the Middle East, followed by South and Central
America (20%) and North America (13%). Figures 12–14 provide statistics on the current global oil
reserve scenario.

Oil Price Dynamics
How Crude Oil Prices are Determined
Global oil demand and supply patterns significantly influence the oil market, along with a number of other
geo-political factors. Prices of petroleum products such as gasoline, diesel, heating oil, jet fuel and
lubricants are relative to crude oil prices.

Demand Side
The world is divided into two major categories on the basis of the demand for oil – OECD and non-OECD.
The OECD bloc consists of the US, a major part of Europe, and other developed countries. These large
economies consume more than 50% of global oil (45.9 MMbbl/d in 2011); however, their rate of
consumption growth is very low. The transportation sector in OECD countries accounts for the majority of
oil consumption. As a result, any economic instability and changes in policies that affect the
transportation sector have a significant impact on oil consumption in these countries.
The developing countries that are not part of the OECD are collectively known as non-OECD. These
countries utilize a greater proportion of their economic activity in manufacturing industries, which are
more energy-intensive than service industries. Although oil consumption by the transportation sector in
these countries is usually lower than in OECD countries, it is rapidly increasing, in line with their
economic growth. In other words, non-OECD countries have a high rate of consumption growth.
Oil consumption in OECD countries fell from 63% in 2000 to 52% in 2011, whereas in the non-OECD
bloc, it increased from 37% in 2000 to 48% in 2011, led by China, India, and Saudi Arabia. Due to
relatively slower economic growth and a more mature transportation sector, the impact of prices on the
consumption of OECD countries is more evident than it is on the consumption in non-OECD countries.
Supply Side
Changes in crude oil production by OPEC countries can have a significant impact on oil prices. The
organization consists of countries such as Saudi Arabia, Iran, Iraq, Kuwait, Libya, the UAE, Nigeria,
Algeria, Angola, Ecuador, Qatar, and Venezuela. OPEC member countries produce c.40% of the world's
crude oil. Also, OPEC's oil exports represent c.57% of the total petroleum traded internationally. The
organization possesses about two-thirds of the world‘s estimated crude oil reserves and has a significant
spare oil production capacity. It influences oil production and, consequently, oil prices, by setting limits
on production by member countries. Historically, multiple reductions in the OPEC production targets have
led to an increase in oil prices.
Non-OPEC members such as North America, regions of the former Soviet Union, and the North Sea
collectively account for 60% of the world production, taking independent decisions about oil production.
Production activities in the non-OPEC bloc are carried out by international or investor-owned oil
companies (IOCs), unlike OPEC, where oil production is controlled by national oil companies (NOCs).
Producers in non-OPEC countries are generally price takers, as they respond to market prices rather than
attempting to influence prices by managing production. As a result, non-OPEC countries tend to produce
at or near full capacity and therefore have little spare capacity.

OPEC), 2011

Other Factors
Other factors that influence oil prices are the inventory balance of countries, natural disasters, political
instability in oil producing countries (e.g., the recent political uprising in Libya and the Iran–US conflict or
historically the Gulf War in the 1990s influenced crude oil prices) and seasonal demand and supply
changes (refer to Figure 17, which shows the impact of geo-political issues on crude prices).
Historical Price Trend
In the short term, demand and supply of oil is inelastic to changes in oil prices. Therefore, any event that
may lead to disruption or create uncertainty in the supply or demand of oil, such as political unrest or
natural disasters, can greatly impact oil prices. Figure 17 shows the fluctuations in oil prices due to 12
major global events over the past 40 years. The most notable disruptions were caused by the Iran–Iraq
war in the early 1980s; Iraq‘s invasion of Kuwait in 1990; the global financial crisis in 2008–09; and
most recently, the political unrest in Nigeria, Venezuela, Iraq, Iran, and Libya. WTI (a light crude oil)
prices increased five-fold from $25/bbl in the 1990s to more than $125/bbl in 2008. However, during the
global recession in 2008–09, oil prices fell from an all-time high of $145/bbl to a low of $35/bbl. The
steep decline in oil prices was due to decreasing oil demand and uncertainty in global economic growth.
However, with recovery in economic growth, oil prices began to improve, averaging at $95/bbl in 2011.

Current Price Trend
Though oil prices averaged at more than $100/bbl in Q1 2012, they declined to below $100 in Q2 2012
because of market concerns related to global economic growth. In Q3 2012, crude prices rebounded and
averaged at about $110, led by the seasonal tightening of oil markets and continuing unexpected
production outages.

Crude Oil Price Benchmarks
Crude oil is differentiated and priced on the basis of internal characteristics such as American Petroleum
Institute (API) gravity and sulfur content, as well as the geographic location of its production. Low-
density (high API) and low-sulfur content (sweet) crude oil is priced at a premium as it can be used more
cost effectively to derive high-value refined products.

Globally, more than 300 different types of crude oil are produced, each with different characteristics. The
two primary benchmarks are West Texas Intermediate (WTI) and Brent Blend. Variants of crude are
priced by assigning a benchmark oil price (such as WTI or Brent) and then making adjustments to
account for the differences in quality, location, proximity to refineries, transportation costs, etc.
WTI
WTI is a light crude oil with API gravity of 39.6 and specific gravity of 0.827. It is described as light
because of its relatively low density, and sweet because of its low sulfur content (0.24%). WTI is used as
a benchmark in oil pricing and is the underlying commodity of Chicago Mercantile Exchange (CME)‘s oil
futures contracts. WTI is refined mostly in the Midwest and Gulf Coast regions of the US and is listed as
WTI, Cushing, Oklahoma.
WTI Pricing
The pricing mechanism used for WTI is simple. Due to the lack of significant forward market, the physical
spot price for WTI is solely based on the NYMEX light sweet oil futures front-month contract. The futures
contract has a contract size of 1,000 barrels, and the delivery point is Cushing, Oklahoma. Most futures
contracts are just financial transactions which are settled before their expiry. A small percentage of
contracts are physically settled.
On the expiry date, the reported WTI price includes the new front-month futures price and the cash costs
of rolling the futures contract.
Brent
Brent crude is a light crude oil with an API gravity of 38.06 and a specific gravity of 0.835. It contains
0.37% of sulfur and is classified as sweet crude, but it is not as sweet as WTI. Brent is suitable for
production of petrol and middle distillates. It is also an acronym for the formation layers of an oil field:
Broom, Rannoch, Etieve, Ness, and Tarbat. It is sourced from the North Sea and is typically refined in
Northwest Europe. It is used as a benchmark for petroleum production from Europe, Africa, and the
Middle East. It is used to price two-thirds of the internationally traded crude oil supplies. To enhance the
trade volumes on exchanges, three additional North Sea crudes have been added to Brent: Forties,
Oseberg, and Ekofisk.
Brent Pricing
Brent pricing is more complex than WTI pricing and depends on the liquidity in the derivatives market.
The key step is the assessment of the spot price (delivery for 10–25 days forward) for the physical
delivery of Brent, commonly known as ‗Dated Brent‘, and is taken as the reference point.
When the forward markets are liquid, Dated Brent prices are derived from 25-day Brent Forwards, which
represent physically deliverable OTC contracts. Brent futures are used to price Dated Brent when the
forward markets lack sufficient liquidity. ICE (Intercontinental Exchange) Brent futures prices are
combined with exchange of futures for physicals (EFPs) values to derive synthetic Brent forward prices,
which are then used to calculate Dated Brent prices.
Forward Dated Brent Curve for up to eight weeks ahead is constructed using contract-for-difference
(CFD) prices. CFD prices are short-term swaps between floating prices and fixed Dated Brent forward
prices. Implied Dated Brent prices for 10–25 days forward can be calculated using this curve. Prices of
the four categories (i.e., Brent, Forties, Oseberg, and Ekofisk) are calculated on the basis of implied

Dated Brent and grade differentials. The published Brent price is the lowest price of the four variants,
which is generally Forties, as it is the lowest in quality.
WTI–Brent Differential
The prices of many crude oil streams produced globally tend to move closely together, although there are
persistent differentials between light-weight, low-sulfur (light-sweet) grades and heavier, higher-sulfur
(heavy-sour) crudes that are lower in quality. Historically, oil prices of various benchmarks across the
world have traded closely to avoid any arbitrary profits.
However, in 2011, a temporary shortage of refining capacity led to a large stockpile of oil at the Cushing,
Oklahoma storage. This stockpile caused WTI prices to be artificially depressed against other benchmarks
such as Brent. While Brent prices increased because of civil unrest in the Middle East, WTI prices declined
as the stockpile at Cushing could not be transported to the Gulf Coast for export. During the period, WTI
prices averaged at $95/bbl, while Brent was priced at $111/bbl. As a result of the price differential, WTI
temporarily lost its status as a barometer of world oil prices. The price differential between WTI and
Brent still continues, but the gap is expected to decrease gradually, as additional pipeline capacities, such
as the Seaway expansion and the southern leg of Keystone XL, come on stream.

Oil Industry – Overview
Oil and gas play a very critical role in driving the global economy. The origin of the modern oil industry
dates back to the late 19th century. The invention of the kerosene lamp in the mid-1850s led to the
establishment of the first US oil company, the Pennsylvania Rock Oil Company of Connecticut. The
company started its drilling operations in 1859 at Titusville; additional discoveries near these wells led to
the creation of a number of oil companies and rapid growth in the oil industry. Oil replaced most of the
other existing fuels for motorized transport, and the global automotive industry adopted oil as its primary
source of energy.

Some of the major oil companies founded in the 19th century include the following:
• Standard Oil Company: Founded in 1870
• Gulf Oil: Founded in 1890
• Texaco: Founded in 1901
• Royal Dutch Shell: Founded in 1907
• Anglo-Persian Oil Company: Founded in 1909
• Turkish Petroleum Company: Founded in 1910
Standard Oil of New Jersey became Exxon, Standard Oil of New York became Mobil, and Standard Oil of
California is now known as Chevron. These oil giants, along with Royal Dutch Shell, Texaco, Gulf, and BP,
are known as the ―seven sisters.‖
At the beginning of the 20th century, oil production was dominated by three regions: the US, Russia, and
the Dutch East Indies (Indonesia). During the first decade of the 20th century, major efforts were made
to explore, develop and produce oil in the Middle East region. Oil exploration began in Iran, followed by
Turkey, Kuwait, and Saudi Arabia.
Industry Structure
The oil and gas industry is divided into the following four sub-segments:
• Upstream (exploration, development and production of crude oil or natural gas)
• Refining (oil tankers, refiners, retailers, and consumers)
• Marketing
• Services

Petroleum Fiscal Regime
The petroleum fiscal regime is basically the contract or the system that decides the ownership of oil
assets, the percentage share of production and the government mechanism of taxing the production from
a commercial discovery. While there are numerous types of contracts, the following two types are more
common:
1. Concessions or Royalty/Tax System: A concession is an agreement between the host
government or one of its agencies such as a national oil company (NOC) and a contractor (an oil
exploration company or a consortium) that grants the contractor exclusive rights to produce
hydrocarbons from designated oil field/block for a specified period. In return, the contractor pays
a signature bonus or license fee to the government. Once the commercial discovery is
established, the contractor also pays royalties/taxes, as per the terms of the contract. In such
contracts, the ownership of hydrocarbons occurs at the wellhead, and there are typically no cost-
recovery limits. This system is used in a number of countries, including the US, the UK, Norway,
France, Russia, Australia, New Zealand, Argentina, and South Africa.
2. Production sharing contracts (PSC): This is an agreement between the government or one of
its agencies, such as an NOC, and a contractor (an oil exploration company or a consortium) that
gives the contractor exclusive rights to explore hydrocarbons from a designated block, over a
specified period. The contract states the share each party will receive from the commercial
production of hydrocarbons from the designated field. Typically, in these contracts, the oil
company bears the exploration, production, and development costs in return for its stipulated
share of production. The contractor can recover these expenses (known as cost oil) in case of a
commercial discovery. The amount left after deducting cost oil is called profit oil, and is split
between the government and the contractor (i.e., 85% government share and 15% contractor
share), as per the terms of the PSC. If stipulated in the PSC, the share of the contractor may
vary with international oil prices or the production rate. The contractor bears the exploration
costs in case commercial recovery is not feasible from the designated field.
The concept of PSCs originated in Indonesia in the 1960s. These contracts are very popular in the Middle
East and Central Asia. They act as a guiding document for defining responsibilities, resource-sharing
mechanism, and liabilities of the parties to the agreement. These contracts can help countries that lack
the resources (technical and/or financial) to develop oil resources.
Key Elements of PSC: The key components in most PSCs are highlighted in the following figure. The
terms and provisions of the contracts may vary case to case.

Division of Revenue and Profits in PSC: The division of profits is the key element of a PSC. Profit
refers to economic profits, i.e., gross revenue less costs for obtaining that revenue. The government may
get its share of profits in one or all of the following ways:
• Signature bonus or other bonuses
• Royalties
• Profit-based split
• Income tax
Figure 21 explains the division of profits with an example, including some of the elements mentioned
above. In this example, we have assumed 15% royalty (paid by the contractor to the government) on
gross production to arrive at net production. From net production, the contractor is allowed to deduct the
various costs incurred in developing the oil field. These costs include capital expenditure (capex) and
operating expenditure (opex), and are referred to as cost recovery or cost oil (in our example, we have
assumed cost recovery as 30% of gross production). Most of the PSCs have cost-recovery limits, which
(along with royalties) guarantee minimum payout to the government, regardless of whether or not
economic profits are generated. The deduction of cost recovery from net production gives profit oil (also
known as equity oil). Profit oil is the share of production available to all the stakeholders in the field. The
government‘s share is deducted from profit oil to calculate the contractor‘s share. The contractor also
pays corporate taxes on his share of profit oil. Thus, the government‘s share includes royalties (15%),
share of profit oil (33%), and corporate taxes (7.7%), while the contractor‘s share includes cost recovery
(30%) and post-tax share of profit oil (14.3%). In this example, the government‘s total share is 55.7%
(15%+33%+7.7%), while the contractor‘s share is 44.3% (30%+14.3%) of the gross production.

Risk Service Contract (RSC): This is an agreement between the government and a contractor
(generally an oil exploration company) that performs the oil exploration on a designated block for a
specified fee, over a stated period of time. The principal difference between an RSC and a PSC is the
ownership of assets (oil blocks). In case of an RSC, the ownership remains with the government, and the
contractor is paid for its services with no right to the hydrocarbons produced from the designated block.
Practically, pure RSCs are rare, with the only notable example being the Iranian oil buy-backs. (In these
contracts, foreign companies are allowed to make the initial investment in oil projects in Iran, and these
companies subsequently recover the initial investment through the exploitation of the projects‘ final
product: crude, gas, or refined products).
Government Take (Share) for Oil: Figure 22 illustrates the petroleum fiscal systems adopted in
different countries. The government take varies from 30% to 90% in different countries; the trend has
been towards a higher take in the production of hydrocarbons. The government take is the highest in the
Middle East, Africa, and Venezuela and the lowest in Ireland, Peru, and Morocco.

What‘s so typical about oil companies?
Classification of Oil Companies
Upstream Companies
Upstream oil companies are engaged in the exploration of a potential natural resource field (oil and gas),
development of the field after successful discoveries, and commercial production of oil/gas from the
developed natural resource field. The process of survey, exploration, development, and commercial
production takes 3–4 years at each stage. The life cycle of an oil field is explained in Figure 23.
Figure 23: Oil Field Life Cycle

Source: Petroleumonline
Exploration
The exploration phase of an offshore field generally takes 3–5 years and involves the following steps:
1. Design a seismic plan
2. Submit the plan to the government authority for approval
3. Move seismic vessels into the survey field after obtaining approval and deploy steamers to obtain
a 3D seismic survey of the area
4. Set the motor of the vessel to fire air-guns at regular intervals (every 10–20 seconds)
5. Detect the echo from the sedimentary layer below the sea bed using hydrophones and store the
data in magnetic tapes for further analysis
6. Analyze the data to create a sonic graphic image of the area under survey; the pattern of contour
lines are used by geologists to determine the location suitable for the drilling of oil or gas
Development of Reserves
Development involves drilling production wells and constructing infrastructure such as platforms,
processing plant pipelines, and export terminals. This stage involves major capital expenditure outlays.
The selection of drilling platforms depends on circumstances, from shallow waters to deep seas. It also
depends on the depth at which the oil/gas is explored.

The following are different types of drilling platforms:
1. Fixed platforms
2. Compliant tower
3. Sea star
4. Floating production systems
5. Tension leg platform
6. Sub-sea systems
7. SPAR platform
Figure 24 provides a classification of drilling platforms, based on depth for deepwater systems.
Figure 24: Types of Offshore Drilling Platform, Based on Depth of Field

Source: U.S. Minerals Management Service
A fixed platform (FP) is feasible for water depths of up to 1,650 feet and is supported by piles driven into
the seabed. A compliant tower (CT) is a narrow, flexible tower that can operate in water depths of up to
3,000 feet. The sea star, or a floating mini-tension leg structure, is suitable for smaller reservoirs and
operates in water depths of up to 3,500 feet. The floating production system (FPS) is anchored in place
and can be dynamically positioned, using rotating thrusters. Connected to wellheads on the ocean floor,
this system can be used in water depths of up to 6,000 feet. Subsea systems (SS), connected to nearby
platforms, can operate at great depths. However, the drilling and completion cost penalties of subsea
systems make these arrangements less preferable than floating structures.

Classification of Oil and Gas Reserves
Reserves are the major assets of upstream oil companies. Figure 25 provides a broad classification of
reserves.
Figure 25: Resource Classification System

Source: Society of Petroleum Engineers
Reserves are broadly classified into the following two categories:
1. Recoverable reserves (discovered commercial and discovered sub-commercial)
2. Unrecoverable reserves (undiscovered)
Recoverable reserves are further classified into the following sub-categories:
• Proved Reserves (1P): The term refers to estimated quantities of oil and gas that are
reasonably certain to be recovered from a reservoir under favorable economic conditions, i.e.,
prices and costs. Reserves are classified under 1P if it is considered economically viable to extract
oil from them. The area of the reservoir that is outlined for drilling, along with adjoining regions
analyzed through geological and engineering data, is considered as proved reserves. It is also
referred to as P90, i.e., having 90% certainty of being produced.
• Proved plus Probable Reserve (2P): These reserves include proven reserves as well as
reserves that are not yet proven but have more than a 50% chance of being economically and
technologically productive.
• Proved plus Probable plus Possible Reserves (3P): These reserves include proven reserves
as well as reserves that are not yet proven and reserves that cannot be categorized as proven
reserves and have less than a 50% chance of being economically and technologically productive.
Undiscovered Reserves: These include reserves that are yet to be discovered. Monte Carlo simulation
techniques are used to determine the lower and upper bound of such reserves. In the absence of other
significant information about such reserves, the lower bound is considered as their estimated value.

Oil and Gas Accounting Metrics
Revenue Metrics
Revenues of upstream companies are highly dependent on the quantum of oil produced and industry
price levels. Production, in case of upstream companies, mainly comprises crude oil, natural gas, and
natural gas liquids.
Oil prices across the industry are dependent on the global demand and supply of oil, economic
conditions, production quotas imposed by OPEC, and supply interventions. The price of natural gas is
closely aligned with the demand and supply condition in respective regional markets.
Cost Structure
The following are some of the major costs associated with an upstream oil company:
• Acquisition Cost: This refers to the cost incurred in the course of acquiring the rights to explore,
develop, and produce oil or natural gas. It includes expenses related to either the purchase or
leasing of the right to extract oil and gas from a property not owned by the company. Also
included in acquisition costs are any lease bonus payments paid to the property owner, along
with legal expenses, and title search, broker, and recording costs.
• Exploration Cost: This refers to the costs incurred for the purpose of determining the existence,
location, extent, quality, or economic potential of a mineral deposit. It also includes costs
associated with drilling a well, and are considered as intangible or tangible. Intangible costs are
usually those incurred before the installation of drilling equipment, whereas tangible drilling costs
are those incurred while installing and operating the equipment.
• Development Cost: This refers to the costs incurred in the preparation of discovered reserves
for production, such as the construction or improvement of roads to access a well site, with
additional drilling or well-completion work, and installing other needed infrastructure to extract
(e.g., pumps), gather (pipelines), and store (tanks) the oil or natural gas from reserves.
• Production Cost: This refers to the costs incurred while extracting oil or natural gas from
reserves. It includes wages for workers and electricity for operating well pumps.
Accounting for Costs
Successful Efforts Method
The successful efforts (SE) method allows a company to capitalize only those expenses that are
associated with successfully locating new oil and natural gas reserves. For unsuccessful results, the
associated operating costs are immediately charged against revenue for that period.
This method assumes that the ultimate objective of an oil and gas company is to produce oil or natural
gas from reserves that it locates and develops, so that only those costs relating to successful efforts get
capitalized. On the contrary, as there is no change in productive assets with unsuccessful results and
therefore costs incurred with this effort should be expensed.
Full Cost Method
The full cost (FC) method allows all operating expenses relating to locating new oil and gas reserves—
regardless of the outcome—to be capitalized. This method conveys that the dominant activity of an oil

Valuation of Oil Companies



23

and gas company is the exploration and development of oil and gas reserves. Therefore, all costs
incurred in pursuit of that activity should first be capitalized and then written off over the course of a full
operating cycle.
Refining
Introduction
Refiners separate derivative products from crude oil. Major global refining players include Koch
Industries, Exxon, BP Plc, Royal Dutch/Shell, Chevron Texaco, and Conoco Philips. However, the refining
business has been dominated by major integrated oil players such as Exxon, ConocoPhillips, Shell, and
BP, with their combined distillation capacity of ~25% of the total supply.
Historically, Europe and the US have been the dominant regions in the refining industry, with a majority
of the capacity in these regions. However, over the past two decades, most Greenfield projects and
capacity additions have been happening in developing regions, particularly China. The advantages of high
volume growth, coupled with easy access to raw materials (especially in the Middle East), have resulted
in sharp capacity growth in Asia. China now controls 12% of global refining capacity, and the remaining
Asian countries contribute 20%. The US still remains the global refining capacity leader, with 19% of
capacity.

1965–11

Source: BP statistical review Source: BP statistical review
Refining: Capital-Intensive and Low-Margin Business
Refining, the least preferred business of oil companies, is characterized by high capital, low margins (3-
4%), low growth, environmental issues, and political sensitivity. However, if managed efficiently with
limited capital, the refinery business can generate strong cash flows and decent returns on invested
capital. Throughout the past century, oil demand has been pretty strong, thereby generating handsome
returns from the refining business. However, there have been times when demand has dropped, resulting
in low operating rates and pressure on profitability – most recently during the 2008–09 financial crisis,
when demand declined by 1.14 Mbd and operating rates slumped to ~80%.

Refining Process
Refining is the process of converting crude oil into usable products such as LPG, gasoline, kerosene,
diesel, lubricating oil, and petroleum coke. The function of an oil refinery is to convert crude oil into
products with more commercial value. Different refiners, depending on the location and configuration of a
refinery and the type of crude, follow different procedures.

Oil Refinery Fractional Distillation Process
Distillation is the process of separating crude into different hydrocarbon groups of different boiling points.
Crude oil is heated and products are separated based on their boiling points. The following are the two
types of distillation that are normally performed:
1. Atmospheric Distillation: Crude oil is heated at a temperature of 350–400°C. Lighter products
such as LPG, naphtha, and gasoline are derived at the lowest temperature, followed by kerosene
and diesel. Heavy products are recovered at a temperature of about 350°C.
2. Vacuum Distillation: Residue is further transferred to a second distillation column to recover
additional heavy distillates. Hydrocarbons with boiling points close to 450°C are separated
without partially breaking them into unwanted products such as coke and gas.

Conversion
Conversion or upgrading alters the chemical structure of hydrocarbons to match the requirements of the
market. For example, if the output from crude includes 30% gasoline and 40% residue, a more
sophisticated refinery using conversion can alter the product slate to 65% gasoline and 5% residue.
Treatment Process
After refining, various treatment methods are used to remove non-hydrocarbons, impurities and other
constituents in order to improve the efficiency of the conversion process as well as the quality and
properties of gasoline.
Revenue Sources of Refiners
Refining companies primarily derive their revenue from the following services:
• Refinery services: Companies may enter into refining operations, which involves removing sulfur
from natural gas and hydrocarbon stream.
• Pipeline transportation: Pipeline transportation includes the transportation of crude oil, natural

• Industrial gases: Companies may also supply carbon dioxide to industrial customers.

• Supply and logistics: Companies often provide terminaling, blending, storing, marketing,
gathering, and transporting of oil, and other supply and logistics services to third parties.
Earnings of refining oil companies are closely tied with the fee they charge for transportation of crude oil,
which is regulated by the government. Pipeline revenues are a function of the level of throughput, the
particular point where crude oil was injected into the pipeline, and the delivery point.
Cost Structure
A refiner incurs costs specific to its operations. These costs include the following:
• Pipeline operating costs
• Transportation costs
• Development costs
Gross Refining Margin: Key Profitability Indicator
Gross refining margin (GRM) is an indicator of the profitability and margin trend of a downstream
company. It shows the incremental revenue that can be earned by converting crude oil into end products
and is calculated by subtracting crude price from the price of refined products. Gross margins of a
refinery are influenced by various factors, including crude oil composition and prices and complexity of
refinery.
Different refined products have different market values. Gasoline and diesel typically sell at a premium to
heavy fuel oils. At times of rising crude prices, transport fuel prices move up due to lack of substitutes.
But in the case of heavy fuels, the upside is limited due to the availability of alternatives (coal and
natural gas). As a result, refineries equipped to convert lower-value products into higher-value products
enjoy extra benefits and higher GRMs.
Ideally, differences in the composition of crude should reflect in the prices of different crude oils. For
example, light crude trades at a premium to heavy crude, as it contains products with higher commercial
value. However, not all refineries are equipped to process heavier, sour blends; therefore, during times
of tight supply of light, sweet oil, refiners that can process heavy, sour crude will have an edge over
others.
Factors Affecting Refinery Performance
Although all refineries convert crude oil into petroleum products, profitability of one refinery may differ
from another. As discussed, refiners can modify their processes to alter output slate. Refinery complexity
plays a major role in determining margins, followed by other factors such as the type of crude oil,
location of refinery, method of crude delivery, and the overall efficiency of the refinery.
• Refinery Configuration: While a simple refinery has more rigid product yield and is focused
only on crude oil distillation, a complex refinery is equipped with catalyst crackers, hydro-
crackers, and fluid cokers that can change the product output slate. A complex refinery has the
flexibility to shift toward a more commercially valuable output slate by producing more high-
value products. Complex refineries also have the flexibility of using lower-priced crude. However,
complex refineries are more capital-intensive and may not necessarily match the returns on
capital of a simple refinery.

• Nelson Complexity Factor: Developed by Wilbur L Nelson in 1960–61, the Nelson Complexity
Factor is the most recognized and commonly used measure of refinery complexity. It describes
the proportion of secondary conversion unit capacities relative to primary distillation. A factor of
one is assigned to the primary distillation unit, and all other units are rated in terms of their cost
and complexity relative to the primary unit. The complexity of a refinery is calculated by adding
the complexity of each piece of refinery equipment – ―complexity factor x unit capacity/crude
distillation capacity‖.
• Crude Choice: The second most important factor affecting the profitability of a refinery is the
type of crude available. Lighter crude contains more commercially valuable products, such as
gasoline and naphtha, than heavy crude. Sweet crude has less sulfur content, making it more
cost-effective, as sour crude attracts extra cost to eliminate sulfur. As light, sweet crude has an
advantage over heavy, sour crude, the refining industry is more inclined toward processing light,
sweet crude such as Brent and WTI over Russian Urals and Mexican Maya. Therefore, in a tight
demand-and-supply market (high demand or less light, sweet crude supply), refiners equipped to
process heavy, sour crude find themselves in an advantageous position over simple refiners,
which experience sharp rise in costs and low margins due to their inability to process heavy
crude.
• Location: There is a major difference between coastal and inland plants. Coastal refiners have
the advantage of low crude supply costs and better access to export markets, whereas inland
refiners are generally closely located to high-demand areas and may be specifically configured to
cater to that market. Moreover, location affects freight, product dispatch, labor, and
environmental compliance costs.
Crack Spreads
GRMs per barrel for a refinery are commonly referred to as crack spreads. These spreads are an
important indicator of the profitability of a particular market or region, as they are calculated using global
oil and local end-product prices. Crack spread calculation depends on the configuration of the plant and
can be calculated using either a single product or multiple products.
• Single-Product Crack Spread: A single-product crack spread is the difference in the price of a
barrel of crude oil and a single refined product. The most common single product spread is the
gasoline crack spread.
Figure 31 compares the crack spread for Singapore naphtha, gasoline, jet kero, and diesel with Dubai
Fateh crude prices.

• Multiple Product Crack Spread: It is the difference between the value of the weighted average
of multiple refined products and a barrel of crude oil. The most commonly quoted multiple
product crack spread is the 3:2:1 crack spread, which compares three barrels of crude oil with
two barrels of gasoline and one barrel of distillate.
2004–08: Golden Period of Refining Profitability
The 2004–08 periods is referred to as the golden period for refining profitability. Continued strong
demand growth, coupled with higher utilization rates, led to higher margins and returns from refining.
However, the global financial crisis of 2008–09 brought an early end to the dream run, with refining
margins dropping to pre-2004 levels. Demand declined after two-and-a-half decades, and operating rates
also dropped sharply. Supply of bio fuels for blending and NGL production further added to the downward
pressure on margins. Since 2008, utilization rates have remained low, and with many refiners closing
down units, there has been a slight recovery in margins.

Marketing refers to distribution and sale of refined crude oil products to retail and wholesale customers
beyond the refinery gate. The marketing operation is the public face of an oil company, as people
working in this function directly interact with the general public on a day-to-day basis. The key role of
marketing is to secure the end markets for products from refining operations. The main players in the
marketing value chain include the marketing company, wholesalers, retailers, industrial/commercial
customers, and retail customers. Marketing companies generally sell their products directly or through
dealer-owned franchisee networks.
• Direct Selling: Under this model, the company may sell its products directly to customers
through a chain of company-owned and -operated retail outlets. The advantage of this sales
model is that the company gets to deal directly with customers. But this model requires large
investment in retail outlets, which should be located in the right places to attract volumes.
• Franchise Network: Under this model, a company selects a dealer, who invests in setting up
retail outlets and sells the company‘s product, following strict guidelines.
The distribution channel may also be classified based on whether the product is sold directly to the end
customer or to wholesalers and retailers, who then sell it to end customers.
Figure 33: Marketing Value Chain

Volumes: Key to Success in Marketing Business
Marketing is a large-volume, but low-margin business. Marketing margins typically range from 1% to
2%. Given the low margins, volumes are the key to success in this business. This highlights the
importance of having well-located retail outlets.
Marketing Margins Impacted by Crude Oil Prices, but not as much as Refining Margins
Marketing margins are affected by changes in crude oil prices. Margins are negatively affected when
crude prices increase as it takes time to pass on the cost to customers, while crude prices are adjusted
immediately, thus increasing the input cost. In some cases, retail prices may be regulated by the
government (e.g., diesel prices in India). This implies that there can be significant delay in passing on
this cost to customers. Conversely, marketing companies make good margins in a declining oil price
scenario, as benefits (lower costs) are often passed on with a delay. Marketing margins are normally
stable on an annual basis, although there could be significant volatility in the short term, due to changes
in the prices of refinery output (e.g., run-up in the prices of refined products ahead of the driving season

margins.
Oil services
Introduction
The oil service industry is the backbone of upstream oil companies. It provides rigs to integrated oil
companies and exploration and production (E&P) integrated companies on a contractual basis. Some of
the other services provided by the oil service industry include seismic testing, transport services, and
directional services. The revenue stream of the oil service industry depends on the revenues, profits, and
capital spending of independent and integrated oil companies and E&P companies whose revenues and
profits are closely interlinked with customer needs. The capital investment in exploration, seismic
activity, drilling activity, and construction generally increases in periods of economic expansion, when the
demand for oil and its various derivatives increase. Factors that contribute to increased capital spending
in the oil and gas exploration industry include current and estimated hydrocarbon prices, oil and gas
demand expectations, upstream cash flow, and reservoir depletion rates. Figure 34 shows the expected
increase in global E&P spending in 2012 (vs. 2011A), with all regions increasing their E&P spending.
Some of the major oil services companies are Schlumberger Ltd, Halliburton, and Baker Hughes Inc
(BHI).

• Offshore rigs
Onshore rigs are used to explore oil and gas below the land surface, while offshore rigs are generally
used to explore oil and gas beneath the sea bed.
Rigzone provides and manages data on rig fleet by region and type, as well as the average daily rates for
contracting a particular type of offshore rig. Figures 35 and 36 provide information on offshore rig fleet
by region and type for CY2012. Figure 35 provides information on the utilization levels worldwide in
CY2012 (the ratio of rigs contracted to rig fleet)—highest in Europe (90%) and lowest in North America
(41%). Figure 36 shows the highest utilization for semi-submersible rigs and the lowest for submersible
and inland barge.

Valuation of Oil Companies
The valuation of oil and gas companies is tricky as we do not assume the cash flows until perpetuity. We
determine the resources and reserves (of various types) with different possibilities and probabilities. This
section explains the different valuation methodologies for E&P companies.
Valuation Methodologies
The business of E&P companies depends on the prevailing market prices, as they are price takers.
Production and capex decisions are based on the current and future price expectations of commodities.
Typically, we do not use cash flow or income-based approaches to value E&P companies.
The following are the two methodologies used for valuation:
• Absolute valuation
• Relative valuation
Absolute Valuation
Absolute valuation involves a fundamental analysis of the company in consideration. It requires
information about the past performance and the prevailing economic and industry conditions to forecast
revenue and cost structure.
We use an NAV model instead of a DCF model to value companies. DCF is more suitable for valuing
companies that are focused on refining, marketing and selling or cater to E&P companies as a services
company. DCF is not an appropriate methodology to value E&P companies because their assets deplete
and they are not expected to generate profits indefinitely. In addition, E&P companies have high capex
requirements, which may sometimes result in negative free cash flows (FCF). NAV, which is an
alternative to DCF, is more appropriate for valuing upstream oil companies.
NAV
The NAV model assumes that the company being analyzed operates and makes an economic profit from
its existing reserves, which obviates the need for additional expansionary capex in the future. This model
is typically built to value an asset with a finite life. We can obviously model different growth and de-
growth assumptions (explained in more detail in the case study). All assets are valued separately and
added to derive the value of a company.
NAV considers the present value of post-tax cash flows from reserves (usually at a 10% discount) as well
as the present value of cash flows from future exploration activity. The calculation is dependent on the
company‘s undeveloped acreage and drilling prospects in that acreage, which calls for a careful study.
The steps to value an oil or gas asset through this method are as follows:
1. We estimate reserves, production, oil price, and discount rates on the basis of information
available in company filings or from specific databases such as Woodmac. Please refer to the case
study on ABC Corp. presented in Figure 41 for assumptions. The case study shows that the life of
the company‘s assets is until 2052, with growth until 2021, followed by a decline in the later
years. One can also determine the asset life based on reserve life ratio (R/P ratio). We use the
industry standard of a 10% discount rate.
2. We estimate commodity prices and map production by year. Reserves deplete due to production
every year. The estimated realized price is multiplied by production to arrive at annual revenue

35

from different commodities. A sum total of various commodity revenue streams results in the
combined revenue for each year over the life of the asset.
3. We estimate other expenses such as production and development expenses and tax rates. We
exclude overhead expenses such as SG&A and expenses that fall into the corporate category.
4. Finally, all cash flows are discounted by the discount rate, using the Net Present Value (NPV)
function.
5. All other assets are valued using the techniques applicable to that particular asset and summed
up to arrive at the final enterprise value (EV).
6. We then add cash to the EV and subtract debt to calculate the equity value.
DCF: A DCF analysis discounts FCF projections, generally at the weighted average cost of the capital
(WACC), to derive current value, which is then used to evaluate the potential for investment. If the value
arrived at through a DCF analysis is higher than the current cost of the investment, the opportunity is
worth considering.
The following adjustments are done when applying DCF to value midstream and downstream companies:
• Additional non-cash expenses, such as depreciation, depletion, and amortization (DD&A) and
stock-based compensation are added to earings (EBIT) while calculating FCF. DD&A is an
accounting method typically used for E&P companies.
• For a terminal exit multiple, a daily production, EBITDA, or EBITDAX-based multiple is used
instead of an FCF multiple. As we know at the onset that the asset is not a going concern and will
not last for perpetuity, we do not have any formulae that incorporate perpetuity.
Midstream and downstream companies do not possess oil or natural gas reserves. They purchase oil from
upstream companies and operate in the transportation and refining segments. The NAV methodology is
not applicable to these companies because their earnings are dependent on their operations and not on
assets as in the case of an E&P company. DCF and relative valuation can be effectively used to value
companies that operate in the midstream and downstream segments.
Relative Valuation
Relative valuation refers to the comparison of an asset price with the market value of similar assets. In a
relative valuation, the value of a company is determined in relation to how similar companies are priced
in the market. It includes trading and transaction comparables.
Commonly Used Valuation Multiples for Oil Companies
• EV/EBITDA or EV/EBITDAX: EBITDAX (rather than EBITDA) multiple is used to value E&P
companies. EBITDAX is EBITDA before exploration costs for successful efforts. In addition, other
non-cash expenses, such as impairments, accretion of asset retirement obligation, and deferred
taxes, should be added back in the EBITDAX calculation. For full-cost firms, exploration costs are
included in depreciation and depletion. EV/EBITDAX is the most popular valuation technique to
determine the value of any oil and gas company.
• EV/Barrels of Oil Equivalent per Day (EV/boe/d): This metric does not take into account
the potential production from an undeveloped field. An undeveloped field obviously has a value,
but if a company has a higher share of undeveloped fields, this multiple may not give the right
picture.

Valuation of Oil Companies



36
www.evalueserve.com | © 2013 Evalueserve. All Rights Reserved
• EV/Proven plus Probable Reserves (EV/2P): The most commonly used metric is EV/2P or
EV/Proven plus probable reserves. This and daily production (barrels of oil equivalent per day)
are the two widely used criteria in cases where cash flows are not known with certainty.
• EV/Debt-Adjusted Cash Flows (EV/DACF): EV/DACF is a proxy of EV/EBITDA after tax. This
measure is not affected by a company‘s capital structure. It determines a business‘s value after
paying off debt. EV/DACF is a multiple applicable to all oil companies, i.e., upstream, midstream,
and downstream companies.
The value of a company, P, is estimated by multiplying the mid-cycle DACF with the mean/median
multiple used for comparable companies (peer group), EV/DACF. Thus,
Pi = (EV/DACF)*DACFi
Where, DACF = NOPAT + Depreciation
EV/DACF is an important multiple as it takes into consideration the after-tax value, which is important
given that oil and gas is a sector that is generally taxed heavily. The above-mentioned metric is also
independent of the impact of financial decisions and thus facilitates a fair comparison across the sector.
Operating Performance Indicators
The following are the two most common operating performance ratios used to assess the performance of
oil companies:
1. Return on Average Capital Employed (RoACE)
Return on capital employed is calculated as
RoACE =



Here, net income refers to the income after minority interest. Average capital employed is the sum of
shareholders‘ fund and net interest bearing debt.
It measures the capital return, which is an important input for valuation analysis. However, this ratio is
not without drawbacks. For example, it measures only short-term accounting profitability. The ratio is not
a true indicator of performance. When investment falls and capital assets depreciate, RoACE rises.
2. DACF
DACF is generally after-tax cash flow from operations plus after-tax debt-service payments, where after-
tax cash flow is the sum of net income, depreciation, exploration charge and other non-cash items.

DACF = Net operating profit after tax (NOPAT) plus Depreciation
In addition to these two parameters, various other operating performance measures exist, depending on
upstream, midstream, and downstream companies.

Case Study: Valuation of an Upstream Oil Company
- NPV
ABC Corp.
ABC Corp. is one of the world‘s largest E&P companies. Headquartered in Woodlands, Texas, ABC
operates in some of the most prolific oil and gas basins in the world. Its major assets are located in the
Gulf of Mexico, the Rocky Mountain region, Alaska, West Africa, Mozambique, and China. Being an E&P
company, ABC‘s growth is driven by its proved reserves and the annual additions to its reserves. ABC
classifies its proved reserves as proved developed and proved undeveloped reserves.
Proved developed reserves are those wherein oil and gas can be extracted from existing wells, using the
available technology and equipment. See Section 5.1 for a detailed description. Proved undeveloped
reserves are those wherein the certainty of finding oil and gas has been established, but new wells need
to be drilled for production or significant capex is required to sustain production at existing wells.
ABC has successfully enhanced its reserve base and has ensured growth in its production rate. Figure 42
provides a summary of ABC‘s proved reserves, as on January 1, 2012.
Note: As on January 1, 2011, the liquids 2P reserves were 850 MMBbl.

Estimates of various commodities (until 2020) that are part of ABC‘s oil and gas assets are listed in
Figure 45. (Refer to appendix for data up to 2041). As stated earlier, we have assumed that production
rate initially increases as the reserves are getting replaced (please refer to reserves replacement ratio) at
a slower rate. Based on this assumption, by 2041, production will reach its lowest point, after which the
reserves are assumed to deplete.

Step Two: Reserve Life and Reserve Replacement Ratio
For any E&P company, the life of its reserves is the number of years the oil and gas reserves (1P) would
last at the current rate of production, assuming zero additions in the future.
For ABC, the life of its reserves at end-2011 was as follows:
• For oil, the reserve life is: Proved reserves/production during the year = 890/ (83*365/1000) =
29.27 years
• For natural gas, the reserve life is = 10,870/1403 = 7.7 years

The extraction rate is calculated on the opening balance of reserves to compute the percentage of
reserves converted into production during 2011.
Extraction rate for oil is = (83.30*365/1000)/890 =30/890 = 3.42%
Extraction rate for gas = 1403/10870 = 12.9%
Figure 47: Extraction Rate for 2011

The growth of an E&P company also depends on its ability to replace its exhausting resources with newer
finds. The idea is to avoid a decline in reserve life. The metric that describes this capability of an E&P
company is called the reserve replacement ratio. A reserve replacement ratio of greater than one
signifies greater additions to reserves than production growth. This suggests growth opportunities for the
company.
Reserve replacement ratio = addition to resources during the year/total production during the year
In case actual reported reserves for 2010 were 850mmbl, the reserve replacement ratio for ABC at
the end of 2011 was = (890-850)/30 = 1.33
As the ratio is greater than one, it signifies greater additions to reserves than production growth at ABC.
The rate of production from a well follows a bell-shaped curve, also known as the Hubbert curve. Hubbert
proposed that the production profile of an oil well follows a bell-shaped curve. Production increases
exponentially, reaches a peak, and then starts to decline (see Figures 43 and 44). For oil wells, peak
production may sustain for a very short period. On the other hand, natural gas wells sustain peak
production for longer periods. In other words, instead of a peak for a short duration, natural gas wells
exhibit a plateau-like production profile, where peak production continues for longer periods.
Step Three: Forecasting Revenue
We know ABC‘s production schedule until 2041. Therefore, we derive the revenue for each year by
multiplying the production with the estimated commodity prices. All the related calculations are shown in
Figure 48. Note that the data shown is only until 2025; the data from 2026 to 2041 is shown in the
Appendix. Also, note that these are estimated numbers and are usually available in company filings or
industry databases such as Woodmac.
These production estimates generate sales revenue when multiplied with the expected sales price. The
realized sales price for an oil company is generally different from benchmark prices; therefore, this
differential should be incorporated when forecasting sales prices. This difference may arise due to
company policies and hedging.
The volume of oil or natural gas assumed to be realized at the contract price provides the hedged
revenue.
The portion of oil and natural gas produce that is not hedged is assumed to be sold at company prices,
which are generally different from benchmark prices. This differential, along with the differential between
company and average prices, should be adjusted while computing the realized price.

Revenue Calculation for 2011
The gross revenue of the firm is the sum of revenue from Natural Gas Liquids (NGLs), gas, and liquids.
NGLs revenue = 29*43.43*365/1000 = 459 (in $ million)
Gas revenue = 3.02*1403*365/1000 = 1547 (in $ million)
Liquids revenue = 54*96.5*365/1000 = 1914 (in $ million)
54 is the difference between Liquids daily total production of 83 (in ‗000) minus NGLs daily production of
29 (‗000).
Step Four: Determining NAV
Figure 48: NAV Calculation Sheet for ABC

Source: Evalueserve
Assumptions
• Royalty (Figure 41) is 14.5% of revenue, which is $568 million for 2011. Opex is calculated
separately for both gas and liquids, and summed up. For oil, opex is $9 per bbl produced, and for
gas it is $1 per mcf produced. For 2011, opex is (9*83*1,000*365+ 1*1,403*365*1,000)/10^6
= $786m. We also assume an annual inflation of 2% on the rate.
• Royalty and opex for further years is calculated similarly.
• State taxes are calculated on revenues after the deduction of royalty and opex. Our assumption
of a tax rate of 12% leads to a tax of $308 million for 2011. Capex is assumed to grow in the
same way as the increase in production. This means that the expansionary capex will cease to
increase in years when production starts declining (there will be maintenance capex though). In
our estimates, we have taken the expansionary capex until 2021, syncing it with the production
estimates, after which, maintenance capex is taken.
• The accumulated depreciation is estimated to be same as the ratio of the (accumulated
production until the year/end of life accumulated production). Please refer to the Appendix for the
depreciation schedule. The corporate tax rate is assumed to be 35%, which, when applied to
EBIT, results in a profit after tax (PAT) of $1,202 million.
• On the FCF row, we apply the NPV function in MS-Excel to arrive at an EV of $19,683m.

Relative Valuation and Benchmark Indicators
Figure 49, provides a comparison of ABC with the major players in the oil and gas industry that operate
in the same country under similar tax structures and regulations.
Figure 49: Valuation Multiples

Source: Evalueserve
From the date in Figure 49, EV/EBITDA is higher for ABC Corp. than EV/EBITDA of peer average. When
we analyze this, along with other important valuation multiple EV/reserves (EV/2P reserves), we find that
the multiple is higher than the peer or group average. One of the reasons behind ABC multiples lying in
the higher top quartile in the group could be a better reserves quality than its peers. It is also possible
that ABC is able to extract more value out of their reserves.
An analysis of the multiples presented above reveals that while ABC appears to be undervalued relative
to its peers when compared on P/Sales, P/book, and EV/DACF. However it appears overvalued based on
other valuation multiples such as P/Cash flow, EV/EVITDA and EV/reserves. Analysts may have different
opinions but generally EV/EBITDA and EV/reserves are preferred ratios/multiples for valuing upstream
companies.
Benchmark Indicators
We use key performance indicators to measure ABC‘s operating efficiency. Figure 50 compares the
operating performance of ABC with three of its competitors.
Figure 50: Valuation Multiples

Source: Evalueserve
The first two ratios—R/P (reserves/production) and reserve replacement—indicate the longevity of
reserve life and how quickly the company can discover and develop new reserves. ABC‘s R/P ratio for oil
and condensates is 29.3, and for gas it is 7.7. We can see that ABC‘s R/P and reserve replacement ratio
is lower than that of its peers. At 10%, ABC‘s production growth lags behind that of its peer average.
Even on relatively lower parameters, ABC appears to be overvalued on EV/EBITDA and EV/reserves
multiple, signaling a mismatch. Compared with its peers, the value of ABC does not justify its reserves
(growth and production levels); therefore, it should be associated with a sell recommendation.
