In the world of oil and gas, the pursuit of hydrocarbons is driven by profit. Every decision, from drilling a well to refining crude oil, is ultimately evaluated based on its economic viability. But what happens when the cost of extracting and processing oil and gas surpasses the revenue generated? This is where the economic limit comes into play.
Defining the Economic Limit
The economic limit refers to the point at which the revenue from produced fluids (oil, gas, or natural gas liquids) falls below the cost of operations set by the company. Simply put, it's the threshold where extracting and producing hydrocarbons no longer generates a profit, and potentially even incurs a loss.
Factors Influencing the Economic Limit
Several factors contribute to the determination of the economic limit, including:
Consequences of Reaching the Economic Limit
Reaching the economic limit can have significant consequences for oil and gas companies:
Strategies to Extend Economic Life
Despite reaching the economic limit, companies may implement strategies to extend the economic life of a project:
Conclusion
The economic limit is a crucial concept in the oil and gas industry. It serves as a critical factor in decision-making, determining whether a project remains profitable. By understanding the factors that influence the economic limit and employing strategies to extend its reach, companies can maximize returns and ensure sustainable operations in an ever-changing energy landscape.

Scenario:
A company is operating an oil well with the following information:
Task:
1. **Current daily profit:** * Revenue: 1,000 barrels/day * $60/barrel = $60,000 * Cost: 1,000 barrels/day * $40/barrel = $40,000 * Profit: $60,000 - $40,000 = $20,000 per day 2. **Daily profit after one year:** * Production rate after one year: 1,000 barrels/day * (1 - 0.05) = 950 barrels/day * Revenue: 950 barrels/day * $60/barrel = $57,000 * Cost: 950 barrels/day * $40/barrel = $38,000 * Profit: $57,000 - $38,000 = $19,000 per day 3. **Impact of depletion rate on economic limit:** * As the depletion rate is 5% per year, the production rate decreases. This leads to increased cost per barrel as the same fixed costs are spread over fewer barrels produced. * Consequently, the profit margin shrinks over time, leading to a lower daily profit. * This scenario demonstrates how the economic limit is reached when the profit margin is too small to cover costs or becomes negative due to production decline and rising per-barrel costs.
