Scenario:
A reservoir produces 100,000 barrels of oil per year. In the same year, 50,000 barrels of water are injected into the reservoir. The reservoir initially contained 1,000,000 barrels of oil.
Task:
Calculate the amount of oil remaining in the reservoir at the end of the year, assuming no significant changes in the volume of water in the reservoir.
Instructions:
Solution:
Input (Water Injection) = 50,000 barrels Output (Oil Production) = 100,000 barrels Accumulation = Input - Output = 50,000 - 100,000 = -50,000 barrels This means there was a decrease of 50,000 barrels of oil in the reservoir. Therefore, the remaining oil in the reservoir at the end of the year = Initial oil volume - Accumulation = 1,000,000 - 50,000 = **950,000 barrels**.
