In the oil and gas industry, economic life is a critical term, representing the period during which a particular asset, project, or field is expected to generate a positive return on investment. It's not simply the lifespan of the asset; it's the time frame where its operational benefits outweigh the costs involved.
Understanding Economic Life
Imagine a newly drilled oil well. It might be capable of producing oil for 20 years. However, the economic life could be shorter, perhaps 10 years. This is because after a certain point, the production costs (maintenance, labor, etc.) may outweigh the revenue generated from the extracted oil.
Factors Determining Economic Life
Several factors influence the economic life of an oil and gas project:
Importance of Economic Life in Decision-Making
Understanding the economic life is crucial for making informed decisions in the oil and gas industry:
Conclusion
The economic life is a dynamic concept in the oil and gas industry, influenced by several variables. Accurately determining and managing it is crucial for profitability, responsible resource management, and ensuring the long-term sustainability of oil and gas operations. By analyzing the economic life, companies can make informed decisions regarding investments, production planning, and asset management, ultimately contributing to the industry's success.
Instructions: Choose the best answer for each question.

Scenario:
A new oil field is discovered, estimated to contain 100 million barrels of recoverable oil. Initial production is projected at 10 million barrels per year. The current oil price is $70 per barrel, and the operating cost per barrel is $30.
Task:
1. **Total Revenue:** 100 million barrels * $70/barrel = $7 billion
2. **Total Cost:** 100 million barrels * $30/barrel = $3 billion
3. **Estimated Economic Life:** - **Profit per barrel:** $70/barrel - $30/barrel = $40/barrel - **Years to extract all oil:** 100 million barrels / 10 million barrels/year = 10 years - **Economic Life:** Since the profit per barrel is positive, the economic life is equal to the total extraction time, which is **10 years**.
