Oil & Gas Risk Management
Oil and gas risk management is key aspect of an oil and gas company’s
strategic planning and decision-making.
What are the varying amounts of risk inherent in the available
asset investment options?
This oil and gas risk management module addresses how oil and gas
companies plan for and evaluate the various risks in this wide set of
options.
LABOUR-INTENSIVE –V-- CAPITAL-INTENSIVE INDUSTRIES
Industries such as auto manufacturing and homebuilding are considered
labour-intensive, that is, it takes a high number of employees to produce
and assemble the product.
A few parts of the oil and gas industry are also labour-intensive such as
the engineered equipment manufacturing sector of oilfield services.
However, the entire oil and gas value chain requires much more capital
than labour to produce results, so it is termed a capital-intensive industry.
For the purposes of this module:
•
A VERY HIGH capital requirement is in billions of U.S. dollars.
•
HIGH is considered to be $US 500 million to 1 billion.
•
MEDIUM ranges from millions of US Dollars through to $US 500
million.
The Capital-Intensive Industry chart (overleaf) shows the range of capital
requirements and asset lifetime frames for the upstream, processing, and
marketing, and transportation segments of the industry.
CAPITAL INTENSIVE INDUSTRY
Long decision cycles require understanding of pricing fundamentals.
The ranges on the chart should be considered representative, because
capital requirements also change as a project works through its asset life,
for example:
•
Upstream oil and gas capital requirements for seismic and
geological studies are estimated at $U.S. million. An exploration well
can be $US 100 to 200 million, but the development of the producing
field (especially offshore) can be in the $US billions over the 50 to
60-year life of the field.
•
Processing facilities are projected in $U.S. billions: a single gas-toliquids (GTL) plant in Qatar, the largest in the world, was initially
estimated to cost $U.S. 5 billion. However, the final cost has been
expected to reach as high as $19 billion.
•
Marketing, on the other hand, has a relatively low capital
requirement. Even though a good retail service station location can
be quite costly, it is inexpensive compared to the other oil and gas
investments.
•
Transportation assets can cost in the range of $U.S. 100 million (for
a vessel) to $U.S. billion for a new pipeline.
The length of the asset lifetime frame is another major factor affecting
project risk because most oil and gas projects consist of long decision
cycles.
BALANCING INVESTMENT OPTIONS
Each investment option is different from a risk-return standpoint…
Historically, integrated oil and gas companies invested in several different
business segments to stabilise their financial results, because each
segment often experienced a different commodity cycle in price and
margins.
What was desirable was an integrated investment portfolio that offset
these price-margin variations.
In the Balancing Investment Options diagram, low gas prices equal low
returns for upstream oil and gas profits, but good returns for a chemical
plant, because gas is used as the plant feedstock.
Therefore, a balanced portfolio of chemical plants and gas production
could provide stability because gas price variations would offset each
other.
In reality, there is not a one-to-one correspondence in investment profiles
which makes it difficult to stabilise financial results with this simplified
strategy.

A key aspect of today’s oil and gas risk management, planning, and
decision making is accounting for the varying amounts of risk inherent in
the wide range of asset investment options available to companies (refer
to the graph, Illustrative Risk-Return Investment Profile).
The higher the risk, the higher is the potential return on
successful projects.
However, with this elevated risk comes a higher possibility of large
financial loss.
TYPES OF RISK
All Oil & Gas Projects have risk, Exploration & Production (E&P) has more
than others….
There are three key types of risk to manage in all oil and gas industry
projects: economic risk, political risk, and environmental risk. These risks
apply to all large, long lead-time industry capital projects, such as:
•
Onshore drilling rigs
•
Offshore drilling drill ships or semi-submersibles
•
Engineered equipment manufacturing facilities
•
Oil and gas production platforms
•
Refineries
•
Gas-to-liquids plants
Additionally, Exploration & Production (E&P) development projects have
another large item, geological risk. The chart, “Managing Risk Across
the Oil and Gas Industry”, is an index of the relative size of economic
risk as it translates into capital and expense and affects a company’s
financial performance.
Every risk in an oil and gas project needs to be quantified as part of the
project planning and investment evaluation decision process.
ECONOMIC RISK
Economic risk on international projects includes:
•
Oil prices collapse
•
Capital cost overruns
•
High operating costs
•
Loss of demand from the facility
Some overlap occurs with political risk in assessing the factors that also
can affect the economics of a project:
•
Stability in the tax system (regime)
•
Ability to repatriate earnings
•
Currency exchange rate stability
POLITICAL RISK
Political risk is a detailed evaluation of all the risks of doing business inside
a particular country.
A change in country management or political philosophy can often result
in a new evaluation of a host country’s oil, gas, and commodity reserves.
Some examples of possible changes are as follows:
•
Renegotiation of economic terms
•
Change in royalty payment and tax rate structure
•
Revisions to production shares
•
Ability to repatriate interest, profit, and dividends
History has shown that there is a direct correlation between the value of
the commodity or resource and the host country’s relationship with the oil
and gas companies.
As the resource value increases, the host countries take a stronger
position in controlling their commodity assets. The best deals for the
international oil and gas companies seem to be made when the price of a
resource is low; however, the agreements are often re-negotiated when
resource prices increase.
The ultimate political risk is the possibility of expropriation of assets, where
the host government takes over the investment, with or without
compensation. There have been multiple examples of major oil asset
expropriation in the past, consider the following:
•
Venezuela has a long history of expropriating oil assets under
former President Hugo Chavez (but continuing in the new regime).
•
More recently, Russia and Ecuador have also used this technique
to gain control of energy resources.
ENVIRONMENTAL & SAFETY RISK
The other major factor is environmental risk. Environmental impact
statements are a pivotal part of new projects, including detailed attention
to the project’s carbon footprint.
In addition to what is normally considered an environmental risk, such as
pollution or inattention to the ecological surroundings, other items, such
as personnel safety, damage to equipment, fire, flood, and disaster, are
also important. All environmental risks that can affect project economics
need to be considered and quantified. Another substantial environmental
impact item in the upstream today is what the host governments are
calling a “zero-flare tolerance”.
Basically, the operator cannot produce the oil unless an outlet is found for
the associated gas which is often flared, or burnt off, at the well. The
environmental policy of zero-flare has become a significant capital and
expense item in developing new production prospects. However, this
policy is also driving research in uses for this wasted resource. Currently,
diesel generators often provide the electric power needed to run pumps
and other equipment at the well site.
Using the available natural gas to power this equipment could save
significant amounts of money while reducing emissions. Many companies
now have applied environmental risk assessment technology and
resultant economic measurements to every international business
decision.
GEOLOGICAL RISK
In evaluating geological risk, it is important to remember that there is a
very high degree of uncertainty in E&P, that is, the lack of true visibility on
the oil or gas reservoir.
What can only be estimated by maps and seismic data is of great
importance to the success of the future project. Even with all of today’s
seismic and evaluation technologies and very sophisticated computer
modelling, the prospect could still contain:
•
Poor source rock;
•
No reservoir rock;
•
No cap rock;
•
Faulted or poorly consolidated reservoir;
•
Tight sands.
All these factors affect the well’s ultimate productivity economics.
However, none of these factors are well known until the money is spent
to drill exploratory and development wells, each of which can cost in the
tens of millions of dollars.
RISK VS. RETURN PROFILES
The risk-return profiles for an oil and gas company vary greatly by the type
of assets in their existing and planned portfolio. These are some general
assumptions:
•
An asset with a regional business driver and regulated rates, such
as a pipeline, has a low-risk profile and gathers a lower, but stable,
return.
•
E&P projects are considered one of the highest risk options in the
industry and can provide high returns, if successful.
•
Assets impacted by global events like refineries, GTL plants, and
liquefied natural gas (LNG) facilities, which are affected by supplydemand and commodity price fluctuations, have a higher risk profile.
•
Commodity trading is unusual. Because it depends on knowledge
assets, it is considered a very high risk. It is difficult to forecast or
depend on the ability of individuals and groups to correctly forecast
and act on future market direction.
OIL & GAS RISK MANAGEMENT AND DECISION MAKING
Today, corporate planners use asset portfolio optimisation principles and
sophisticated mathematical models to assess various risk-return
relationships. Corporate metrics and quantitative tools are common and
available.
Data indicate that planners and decision-makers who evaluate risk with a
probability profile rather than a single-point estimate make better
investment decisions.
MULTIPLE ANALYSIS APPROACHES USED.
Ways to structure the analysis of risk of future outcomes.
MODELLING RISK
As the chart Multiple Analysis Approaches Used indicates, oil and gas
companies employ 3 basic analysis approaches to develop risk profiles
for the various asset categories and to consistently tie the project analysis
to the company’s long-term business strategy. The analysis approaches
rank from more subjective methods to more quantitative.
Scenario planning was introduced by the Shell Oil Company in the 1960s
to help account for the uncertainty inherent in speculating about the future.
In practice, it consists of three steps:
1. Formulating scenarios
2. Identifying “robust” strategies
3. Developing specific strategic actions or changes in strategy as
events unfold
This technique is the most subjective. However, it is becoming an
increasingly popular concept and tool, because most of the drivers
affecting the industry’s economic results are outside the control of the
traditional oil and gas participants.
Quantitative modelling is the most common technique used by oil and
gas and oilfield services companies when they evaluate physical plants
and facility assets. The basic concept of quantitative modelling, often
called “rank and cut”, is to:
1. Evaluate each project with a consistent set of assumptions
2. Use the same tool and metric to quantify and rank the economic
return potential of each project
3. Budget those projects for which the company has the available
capital
Portfolio management simulates varying combinations of proposed
projects, and especially the interaction among the projects. In this
method, all potential E&P projects are characterised consistently and
objectively with regard to reserves, cash flows, and investments costs.
However, a likely outcome of the analysis is expressed as a probability
distribution of returns—not a single point, or range of returns—which
would be generated in more traditional approaches.
This method is much more sophisticated and demanding, but leads to
better long-term accuracy for E&P assets than the traditional, “rank and
cut” technique.
MORE ON QUANTITATIVE MODELLING
Important concept is the “Time value of Money”…
As project investment options are analysed, an important concept is the
time value of money. The basic premise of this concept is that the
revenue or cash flow achieved in the future needs to be discounted
because it is not as valuable as cash today. The first step in conducting
this type of analysis is to develop a profile of the future, cumulative, cash
flow from the project.
As the “More on Qualitative Modellin”g chart shows:
•
In the early years of project investment, the annual cash required to
fund the project makes the cumulative cash flow negative.
•
As the project is completed and comes onstream, net revenue
(cash) is generated.
•
In the case of E&P projects, the cash generated deteriorates over
time as the field production decline curve takes effect. The cash flow
is also affected by changes in crude oil prices and natural gas prices
as well as unforeseen events that affect production rates, such as
hurricanes and political turmoil.
•
The cash flow stops when the asset is retired or sold.
CORPORATE METRICS
What’s the difference?
Typical corporate planning metrics to analyse the forecasted cumulative
cash flow from a project are:
•
Discounted Cash Flow Return (DCF) or Internal Rate of Return
(IRR) is the discount rate where cumulative cash flow from a project
equals zero. An investment is attractive if its rate of return is greater
than the corporation’s cost of capital, or a hurdle rate return. DCF
and IRR measure the return of an investment relative to the
company’s cost of capital.
•
Net Present Value (NPV) is the point where the cumulative cash
flow from a project is discounted using a percentage factor set by
the company. An investment is attractive if the NPV is greater than
zero. Projects are ranked from the highest NPV (most attractive) to
the lowest during the budgeting process.
•
Return on Investment (ROI) is where the cumulative cash flow is
divided by cumulative capital (plus any overhead on capital, such as
interest cost). ROI describes how much profit is generated per unit
of capital investment.
MORE ON PORTFOLIO MANAGEMENT
E&P Portfolio Complexity….
In E&P companies today, there are typically more assets to choose from
than can be developed with the available capital.
In the context of the long-term corporate strategy, companies must
consider which assets to invest in, when to invest, and how much to invest.
The sheer number of project options is usually a major challenge. For
example, an organisation with even a modest base of 200 E&P assets is
faced with over 1,000 possible options to analyse. The most important
principle in E&P portfolio management is the emphasis placed on
quantifying risk in the individual asset and the interaction among assets.
MONTE CARLO SIMULATION
Mapping the uncertainty that is pervasive in E&P…
Monte Carlo simulation is the most common tool used to help quantify
the risk in E&P projects. The name refers to Monte Carlo, Monaco, known
for casinos where the roulette wheels, dice, and slot machines exhibit
random behaviour. The random behaviour in casino games is like how a
Monte Carlo simulation selects variable values at random to simulate an
E&P portfolio model.
When rolling a die, it is known that either 1, 2, 3, 4, 5, or 6 will come up,
but which number will occur for any roll is unknown. This is very true for
E&P variables affecting a project, variables have a known range of values,
but value for any specific time or event is uncertain, such as:
•
Crude oil prices or natural gas prices
•
Production decline rate
•
Exploration success rate
•
Asset investment cost
•
Foreign tax and royalty rates
Simulation refers to any analytical method meant to imitate a real-life
system. This method is used when more traditional analyses are too
mathematically complex or too difficult to reproduce. A simulation
produces a distribution of results, as shown in the graph, “Monte Carlo
Simulation”, which is a probability profile of the potential project value.
A quantitative or spreadsheet model generating a single-point result is no
longer robust enough for good decision-making in today’s E&P business
environment.
BUSINESS PLANNING CYCLE
Integrated – with new level of sophistication….
Although the decision process among all these different types of
investment options seems complex, global oil and gas industry planners
say the objective, in reality, is fairly simple – to figure out the right mix of
investments to help the company consistently meet its financial and
performance goals.
That is no small feat considering the increasing volatility in oil and gas
markets and the inherent risk, especially in E&P. To integrate the tools
and corporate metrics into an annual oil and gas planning and decision
process, most oil, and gas corporate planners first translate a set of
corporate strategies into guidelines to advise the business units as they
develop projects.
Some examples of corporate strategies include:
•
Percent annual earnings growth
•
Reserve additions
•
Minimum finding costs
•
Minimum returns on facility and process investments
•
Debt-to-equity ratio targets
In most companies, the projects are generated in respective business
units. Systematic evaluation of projects is especially complex when the
company operates and/or has assets in diverse global locations.
A key planning principle in oil and gas is that the portfolio composition and
interactions among the projects cannot be determined at the business unit
level. Responsibility for ranking and selecting projects and evaluating
different portfolio combinations relative to the corporate strategies usually
resides at a central planning group.
Often, an interactive process involving negotiations among business units
and planning ultimately leads to assignments of projects or groups of
projects to each business unit. The central group also assesses
performance (compared against forecasts) and feeds these results back
to each business unit to improve planning in the next cycle.
TYPICAL INDUSTRY PLANNING TIMELINE – LONG RANGE
A two-step process… First the long range (20+ year) outlook…
LONG AND SHORT RANGE PLANNING
Most oil and gas companies use two separate but interrelated planning
processes throughout the year:
•
The LONG-RANGE PLAN is used to forecast capital requirements
for 5 to 10 years and has a planning horizon that matches the life of
the asset under evaluation (25 to 30 years).
•
The SHORT-RANGE PLAN examines the impact of the long-range
plan assumptions on the business in the next 12 to 24 months. This
plan is used to set short-term business unit and personal
performance targets.
The Typical Industry Planning Timeline (Long-Range) chart shows a
typical timeline and activities for a long-range plan, called the planning
cycle, as follows:
•
JUNE/JULY: The corporate planning group develops a set of price,
volume, and market condition assumptions to develop the longrange plan. These assumptions are commonly called the planning
bases.
•
AUGUST/SEPTEMBER: Each business unit puts together its
strategic plans, that reflect the planning bases, and proposes
projects to meet the business unit targets.
•
OCTOBER: The planning group conducts reviews of the proposed
projects across all business units to ensure all capital requirements
needed to make the project successful have been identified.
•
OCTOBER/NOVEMBER: The long-range plan, consisting of a list of
those projects with the highest return or probability of success, is
consolidated and presented to the appropriate approval body. Once
projects are approved, a financial plan to fund the projects is
developed and the business units with successful projects are
notified to begin project development.
TYPICAL INDUSTRY PLANNING TIMELINE – SHORT RANGE
Then the short range (one year) outlook…
For the short-range planning cycle shown in the Typical Industry Planning
Timeline (Short-Range) chart, the key steps are:
•
OCTOBER/NOVEMBER: The best estimate is made of the current
year’s financial results. The impact of the recently competed
financial plan is incorporated with these results to make a 1-2 year
short-term forecast of financial targets.
•
JANUARY/FEBRUARY: The financial targets for the business units
are translated to operational statistics for use by the management
team.
•
NUMEROUS FORMATS are used throughout the oil and gas industry
to convert these targets to individual performance scorecards. The
objective is to ensure that everyone in the organisation knows how
they can contribute to the success of their specific business unit
(refer to the Feedback Importance figure).
IMPORTANCE OF FEEDBACK IN OIL AND GAS RISK MANAGEMENT
Very long-term improvement in shareholder value as measured by
continuous improvement in portfolio quality.
These sophisticated
quantitative and portfolio management tools help experienced
management teams to ask better questions.
CLOSING THE LOOP – HOW DID IT ALL WORK?
OBJECTIVE:
Very long-term improvement in shareholder value as
measured by continuous improvement in portfolio quality.
Consistency and feedback are very important parts of the process.
Corporate planners provide guidance to management using tools that will
help the company meet its goals every year. The investor community
rewards companies that consistently deliver what they say they will.
It is difficult to achieve consistency and improvement in business results
without feedback on capital investment efficiency, especially in oil and gas
investments. The project development and implementation cycle can
often outlast the human element associated with the initial project
decisions.
MEASURING SUCCESS IN AN OIL AND GAS PORTFOLIO
ROCE: RETURN ON CAPITAL EMPLOYED
ROCE = INCOME / AVERAGE CAPITAL EMPLOYED
• INCOME = Income from continuing operations + interest expense
and minority interest (all after tax)
• CAPITAL EMPLOYED = Current Assets + Property Plant &
Equipment + Other Assets… Less Accounts Payable & Liabilities
• AVERAGE CAPITAL = beginning of year and year-end capital
employed, divided by 2
Two major indicators, described in the next two charts, RETURN ON
CAPITAL EMPLOYED (ROCE) and CAPITAL DISCIPLINE REWARDED,
are used as feedback measures by companies and external analysts.
ROCE is the most common indicator used as a measure of the efficiency
of capital investment across the oil and gas industry. As the chart
explains, ROCE is net income divided by the average capital employed in
the business unit or corporation.
This statistic is often reported in a company’s annual report and used for
comparison purposes by industry analysts.
OIL AND GAS RISK SUMMARY
The most important principle in E&P portfolio management is the
emphasis placed on quantifying risk in the individual asset and the
interaction among assets.
The risk-return profiles for an oil and gas company vary greatly by the type
of assets in their existing and planned portfolio.
To integrate the tools and corporate metrics into an annual oil and gas
planning and decision process, most oil and gas corporate planners first
translate a set of corporate strategies into guidelines to advise the
business units as they develop projects.
Most oil and gas companies use two separate but interrelated planning
processes throughout the year:
•
The long-range plan is used to forecast capital requirements for 5
to10 years and has a planning horizon that matches the life of the
asset under evaluation (25 to 30 years).
•
The short-range plan examines the impact of the long-range plan
assumptions on the business in the next 12 to 24 months. This plan
is used to set short-term business unit and personal performance
targets, called scorecards.
RETURN ON CAPITAL EMPLOYED (ROCE) is the most common
indicator used as a measure of the efficiency of capital investment across
the oil and gas industry.
ROCE is net income divided by the average capital employed in the
business unit or corporation.
