Exercise: Calculating Expected Value

Scenario: An oil company is considering investing in a new exploration project. Their analysis suggests the following possibilities:

• Outcome 1: Large oil discovery (50% probability) - Estimated value: $2 billion
• Outcome 2: Small oil discovery (30% probability) - Estimated value: $500 million
• Outcome 3: No discovery (20% probability) - Estimated value: $0

Task: Calculate the Expected Value of this exploration project.

Techniques

EV in Oil & Gas: Beyond Electric Vehicles

This document expands on the concept of Expected Value (EV) in the oil and gas industry, breaking down the topic into distinct chapters for clarity.

Chapter 1: Techniques for Calculating Expected Value

Calculating the Expected Value (EV) involves a straightforward process, yet its accurate application hinges on the precision of input data and the chosen methodology. Several techniques facilitate EV calculation, each with its strengths and weaknesses:

• Simple Expected Value: This is the basic calculation shown in the introduction: ∑ (Probability_i * Value_i). It's suitable for scenarios with a limited number of discrete outcomes.

• Decision Trees: For more complex scenarios involving sequential decisions and multiple branches of possibilities, decision trees offer a visual and organized approach. Each branch represents a possible outcome, with probabilities assigned to each path. The EV is calculated by working backward from the end nodes, summing the weighted values at each decision point.

• Monte Carlo Simulation: When dealing with significant uncertainty in input parameters (e.g., oil prices, reserve estimates), Monte Carlo simulation provides a robust approach. It generates numerous random inputs based on probability distributions, running the EV calculation repeatedly to create a distribution of potential outcomes rather than a single point estimate. This gives a better understanding of the range of possible results and the associated risks.

• Sensitivity Analysis: After calculating the EV, sensitivity analysis is crucial. This involves systematically changing input parameters (one at a time) to observe the effect on the EV. This helps identify the most critical variables that significantly influence the outcome and where more accurate estimations are needed.

Chapter 2: Relevant Models Employing Expected Value

Various models in the oil and gas industry leverage EV as a core component:

• Reserve Estimation Models: These models utilize probabilistic methods to estimate the size and quality of hydrocarbon reserves. EV is integrated to calculate the expected value of reserves, factoring in geological uncertainty.

• Production Optimization Models: These models aim to maximize the net present value (NPV) of production by optimizing production rates, well completions, and facility investments. The EV of different production strategies is compared to select the most profitable approach.

• Risk Assessment Models: These models quantify and manage risks associated with exploration, development, and production. EV is used to assess the expected losses or gains from various risk scenarios, informing risk mitigation strategies.

• Portfolio Optimization Models: Oil and gas companies often have diverse projects. Portfolio optimization models use EV to evaluate the expected returns of different project combinations, helping companies allocate capital efficiently.

Chapter 3: Software Tools for EV Calculation

Several software packages facilitate EV calculations, automating complex calculations and streamlining the analysis process:

• Spreadsheet Software (Excel, Google Sheets): These are suitable for simple EV calculations and sensitivity analyses. Built-in functions and custom formulas can be used to perform the calculations.

• Statistical Software (R, Python, Matlab): These provide more advanced capabilities for Monte Carlo simulations, regression analysis, and complex statistical modeling, improving the accuracy and sophistication of EV estimations.

• Specialized Oil & Gas Software: Several commercial software packages are designed for the oil and gas industry, incorporating EV calculations into broader reservoir simulation, production planning, and risk management modules. These often offer user-friendly interfaces and industry-specific functionalities.

Chapter 4: Best Practices for Effective EV Utilization

Effective use of EV requires careful consideration of several best practices:

• Data Quality: Accurate and reliable data is paramount. Thorough data validation and quality control are essential to ensure the robustness of the EV calculations.

• Probability Assessment: Assigning probabilities to different outcomes requires careful consideration of historical data, expert judgment, and appropriate statistical methods.

• Transparency and Documentation: The assumptions, methods, and results of EV calculations should be clearly documented to allow for scrutiny and facilitate communication among stakeholders.

• Scenario Planning: Consider multiple scenarios, incorporating various potential outcomes and associated probabilities, to better understand the range of potential results.

• Integration with other decision-making tools: EV should not be used in isolation. Integrate it with other techniques such as sensitivity analysis, decision trees, and risk registers for a holistic approach.

Chapter 5: Case Studies Demonstrating EV Application

Several case studies illustrate EV's practical application in the oil and gas industry. Examples could include:

• Exploration project evaluation: A company evaluating multiple exploration sites using EV to prioritize investments based on expected returns, considering factors like geological risk, oil price volatility, and drilling costs.

• Production optimization: An oil company using EV to optimize production rates in a mature field by comparing different strategies considering declining reservoir pressure, maintenance costs, and fluctuating oil prices.

• Risk management: A pipeline company using EV to evaluate the potential financial impact of various pipeline failure scenarios and informing decisions on investment in safety upgrades and insurance.

• Mergers and Acquisitions: An oil company utilizing EV to value potential acquisition targets, taking into account uncertainty in reserve estimations, production costs, and future oil prices.

These case studies would demonstrate the practical application of EV, highlighting the benefits and limitations in real-world scenarios within the oil and gas industry. Each case study would include details of the methodology, data used, and the insights gained from the EV calculation.
