In the oil & gas industry, where projects are complex and resources are often scarce, making informed decisions about allocating resources is critical. Marginal costing is a powerful tool that helps achieve this goal by focusing on the incremental cost of making a change. This article will explore how marginal costing is used in oil & gas, highlighting its benefits and considerations.
Understanding the Concept:
Marginal costing, also known as incremental costing, focuses on the additional cost incurred when producing one more unit of output or implementing a change to a project. This approach is particularly valuable in situations where traditional unit cost analysis is not feasible. For instance, in oil & gas projects:
Key Applications in Oil & Gas:
Marginal costing is particularly useful for analyzing various scenarios in oil & gas operations:
Example:
Consider a drilling operation where adding an extra drilling rig can increase production by 10%. Marginal costing would analyze the incremental cost of the additional rig, including its rental, crew, and operating expenses. This cost would then be compared to the expected increase in production to determine if the investment is worthwhile.
Challenges and Considerations:
While marginal costing offers valuable insights, it's important to consider these challenges:
Conclusion:
Marginal costing empowers oil & gas companies to make informed and cost-effective decisions by focusing on the true cost of change. By understanding the incremental costs associated with various options, companies can optimize resources, improve efficiency, and maximize returns. While challenges exist, implementing marginal costing with careful consideration and analysis can significantly contribute to success in the oil & gas industry.

Scenario: An oil company is considering adding a second drilling rig to an existing operation. The current rig produces 100 barrels of oil per day at a cost of $500 per barrel. The company estimates that adding a second rig will increase production by 20% and incur an additional cost of $250 per barrel for the new rig.
Task: Using marginal costing, analyze whether adding the second rig is a profitable decision.
Instructions:
1. Current total production cost per day: 100 barrels * $500/barrel = $50,000 2. Expected increase in production: 100 barrels * 20% = 20 barrels 3. Additional production cost per day: 20 barrels * $250/barrel = $5,000 4. Total production cost per day with both rigs: $50,000 + $5,000 = $55,000 5. Net profit per day with both rigs: (100 barrels + 20 barrels) * $500/barrel - $55,000 = $10,000 6. Adding the second rig is a profitable decision as it generates a net profit of $10,000 per day.
This chapter dives deeper into the specific techniques used in marginal costing, particularly within the oil & gas industry.
1.1. Basic Marginal Cost Calculation:
The foundation of marginal costing lies in calculating the incremental cost of a specific change. This can be represented as:
Marginal Cost = Total Cost (after change) - Total Cost (before change)
This basic formula applies to various scenarios, including:
1.2. Contribution Margin Analysis:
In oil & gas, contribution margin analysis is a vital tool for understanding the profitability of individual projects and activities. It's calculated as:
Contribution Margin = Revenue - Variable Costs
Variable costs are those that fluctuate directly with production, such as fuel consumption and drilling supplies. This analysis reveals the amount of revenue that contributes towards covering fixed costs and generating profits.
1.3. Break-Even Analysis:
This technique helps determine the production level required to cover all fixed costs. It provides valuable insights into the financial viability of a project.
Break-Even Point = Fixed Costs / (Selling Price Per Unit - Variable Cost Per Unit)
For example, if an oil well has fixed costs of $1 million and the selling price of oil is $70 per barrel, while the variable cost per barrel is $30, then the break-even point would be 25,000 barrels.
1.4. Sensitivity Analysis:
To account for uncertainties in cost estimations and market conditions, sensitivity analysis is employed. This involves varying key variables (e.g., oil price, production volume) within reasonable ranges to observe the impact on profitability.
1.5. Cost Allocation:
In complex projects involving multiple activities, accurate cost allocation is essential. Marginal costing uses a bottom-up approach, assigning costs to individual activities based on their specific requirements and usage. This contrasts with traditional overhead allocation methods that can be less accurate in dynamic oil & gas operations.
1.6. Marginal Costing in Optimization:
By understanding the incremental cost of different options, marginal costing can be used to optimize resource allocation. This could involve:
Conclusion:
These techniques allow oil & gas companies to make informed decisions about resource allocation, project feasibility, and operational efficiency. By focusing on the incremental cost of change, marginal costing helps optimize resource utilization and maximize profitability in a complex and dynamic industry.
