Scenario:
You are an exploration manager for an oil & gas company considering drilling in a new location. You have gathered initial data suggesting good potential for a large oil reserve. However, there are several uncertainties:
Task:
Using the information above, create a simple What-If Analysis to evaluate the potential profitability of this drilling project under different scenarios. Consider at least three scenarios (e.g., optimistic, pessimistic, most likely). Use a basic calculation to assess profitability (e.g., total revenue - total cost).
**Scenario 1: Optimistic** * Oil Price: $100 per barrel * Drilling Costs: $100 million * Production Rate: 15,000 barrels per day **Calculation:** * Revenue per day: $100/barrel * 15,000 barrels = $1,500,000 * Total revenue (assuming a 5-year project): $1,500,000/day * 365 days/year * 5 years = $2,737,500,000 * Profitability: $2,737,500,000 - $100,000,000 = $2,637,500,000 **Scenario 2: Pessimistic** * Oil Price: $60 per barrel * Drilling Costs: $120 million (20% increase) * Production Rate: 5,000 barrels per day **Calculation:** * Revenue per day: $60/barrel * 5,000 barrels = $300,000 * Total revenue (assuming a 5-year project): $300,000/day * 365 days/year * 5 years = $547,500,000 * Profitability: $547,500,000 - $120,000,000 = $427,500,000 **Scenario 3: Most Likely** * Oil Price: $80 per barrel * Drilling Costs: $100 million * Production Rate: 10,000 barrels per day **Calculation:** * Revenue per day: $80/barrel * 10,000 barrels = $800,000 * Total revenue (assuming a 5-year project): $800,000/day * 365 days/year * 5 years = $1,460,000,000 * Profitability: $1,460,000,000 - $100,000,000 = $1,360,000,000 **Conclusion:** This simple analysis demonstrates that the project has the potential to be highly profitable under optimistic scenarios. However, it also highlights the significant risks associated with fluctuating oil prices, drilling costs, and production rates. The results suggest that further investigation and more detailed analysis are needed before making a final decision.
Chapter 1: Techniques
What-if analysis employs several techniques to explore potential outcomes under varying conditions. The core methodology involves identifying key variables, defining plausible scenarios for those variables, and then modeling the impact of these scenarios on relevant metrics. Several specific techniques are frequently used:
Scenario Planning: This involves creating a limited number of distinct scenarios (e.g., optimistic, pessimistic, most likely) representing different potential futures. Each scenario is defined by specific values for the key variables. This is a simpler approach, suitable for initial assessments.
Sensitivity Analysis: This method assesses the impact of changing a single variable while holding others constant. It helps identify the variables that have the most significant impact on the outcome, allowing for focused risk management. This is useful for prioritizing which variables require more precise forecasting or mitigation strategies.
Monte Carlo Simulation: This powerful technique uses random sampling to generate a large number of possible outcomes based on probability distributions for each key variable. This produces a range of potential outcomes and associated probabilities, providing a more comprehensive understanding of uncertainty than simpler methods. It's particularly valuable when dealing with many variables with uncertain relationships.
Decision Tree Analysis: This visual technique maps out possible decision paths and their associated outcomes, incorporating probabilities and payoffs at each decision point. It's useful for evaluating sequential decisions under uncertainty, such as deciding on exploration activities based on initial geological surveys.
The choice of technique depends on the complexity of the problem, the availability of data, and the level of detail required. Often, a combination of these techniques is employed to provide a comprehensive analysis.
Chapter 2: Models
Effective what-if analysis relies on accurate and appropriate models to simulate the impact of different scenarios. Several modeling approaches are used within the oil and gas industry:
Financial Models: These models focus on the financial implications of different scenarios, including project profitability, net present value (NPV), internal rate of return (IRR), and payback periods. They often incorporate detailed cost estimates, revenue projections, and discount rates.
Reservoir Simulation Models: These complex models simulate the flow of hydrocarbons within a reservoir, taking into account factors like reservoir pressure, permeability, and fluid properties. They are essential for optimizing production strategies and predicting future production rates under different development scenarios.
Production Optimization Models: These models aim to maximize production efficiency and minimize operational costs. They consider factors such as well placement, production rates, and facility capacity.
Economic Models: These broader models analyze the impact of macroeconomic factors such as oil prices, exchange rates, and interest rates on project profitability.
Environmental Models: These models assess the potential environmental impact of different development options, considering factors such as greenhouse gas emissions, water usage, and waste disposal.
The selection of the appropriate model(s) depends on the specific question being addressed. Sophisticated models may require specialized software and expertise.
Chapter 3: Software
A range of software tools facilitates what-if analysis in the oil and gas industry:
Spreadsheet Software (e.g., Excel): Excel is widely used for simpler what-if analyses, particularly scenario planning and sensitivity analysis. Its ease of use and widespread availability make it a valuable tool for preliminary assessments. However, its limitations become apparent when dealing with complex models and large datasets.
Specialized Reservoir Simulation Software (e.g., Eclipse, CMG): These powerful software packages are used for complex reservoir simulations, enabling detailed modeling of fluid flow and production performance under various scenarios.
Integrated Production Optimization Software: This software combines reservoir simulation with production optimization models to optimize field development plans.
Financial Modeling Software (e.g., Capital Budgeting Software): These tools provide specialized functionality for creating and analyzing complex financial models.
Programming Languages (e.g., Python, R): These languages offer flexibility for developing custom models and conducting more sophisticated statistical analysis. They are often used in conjunction with other software packages.
The choice of software depends on the complexity of the analysis, the available budget, and the technical expertise of the users.
Chapter 4: Best Practices
Effective what-if analysis requires careful planning and execution. Key best practices include:
Clearly Define Objectives: Establish clear objectives for the analysis before beginning. What questions are you trying to answer? What decisions need to be informed?
Identify Key Variables: Carefully select the key variables that are likely to have the most significant impact on the outcome.
Develop Realistic Scenarios: Use available data and expert judgment to develop plausible scenarios that reflect the range of potential future outcomes. Avoid overly optimistic or pessimistic scenarios that are not grounded in reality.
Use Appropriate Models: Select models that are appropriate for the complexity of the problem and the available data.
Validate Models: Validate the models used to ensure they accurately represent the real-world system being studied.
Document Assumptions and Limitations: Clearly document the assumptions made and the limitations of the analysis.
Communicate Results Effectively: Present the results of the analysis in a clear and concise manner, using visualizations and other tools to communicate complex information effectively.
