Instructions: Choose the best answer for each question.
1. What is Recoverable Gas Lift Gas?
a) Gas injected into a well for lift purposes that is lost or flared.
Incorrect. Recoverable Gas Lift Gas is recaptured and reused.
b) Gas injected into a well for lift purposes that is subsequently recaptured and transferred back into the pipeline.
Correct! Recoverable Gas Lift Gas is recycled back into the production process.
c) Gas naturally produced from a well that is used for lift purposes.
Incorrect. This describes produced gas, not Recoverable Gas Lift Gas.
d) Gas used to power equipment at the well site.
Incorrect. This is a different type of gas usage.
2. What is a key benefit of using Recoverable Gas Lift Gas?
a) Increased wellbore pressure.
Incorrect. Gas lift actually reduces wellbore pressure.
b) Reduced environmental impact.
Correct! Reusing gas reduces the need for flaring, which releases harmful gases.
c) Increased oil viscosity.
Incorrect. Oil viscosity is not directly affected by gas lift.
d) Increased production of natural gas.
Incorrect. While gas lift can enhance oil production, it doesn't directly increase natural gas production.
3. Which of the following is NOT a key consideration for Recoverable Gas Lift Gas?
a) Gas quality.
Incorrect. Gas quality is crucial for effective reuse.
b) Oil production rate.
Correct! Oil production rate is not a direct consideration for Recoverable Gas Lift Gas itself, although it influences the overall gas lift process.
c) Compression and transport.
Incorrect. These are essential steps in the gas recovery process.
d) Separation and treatment.
Incorrect. The gas may need to be separated and treated before reuse.
4. How does Recoverable Gas Lift Gas contribute to sustainability?
a) By reducing the need for flaring, which releases greenhouse gases.
Correct! Reusing the gas reduces the need for flaring, making the process more environmentally friendly.
b) By increasing the use of renewable energy sources.
Incorrect. Recoverable Gas Lift Gas is not a renewable energy source.
c) By reducing the amount of oil extracted from the ground.
Incorrect. Recoverable Gas Lift Gas actually helps maximize oil production.
d) By promoting the use of cleaner fuels.
Incorrect. While it promotes efficiency, it doesn't directly contribute to cleaner fuels.
5. Which of the following statements about Recoverable Gas Lift Gas is TRUE?
a) It is always a cost-effective solution for all wells.
Incorrect. The cost-effectiveness depends on factors like gas quality and infrastructure.
b) It requires specialized equipment and infrastructure for recovery.
Correct! It requires dedicated equipment and infrastructure to capture, compress, and transport the gas.
c) It is only used in offshore production platforms.
Incorrect. Recoverable Gas Lift Gas can be used in both onshore and offshore operations.
d) It is a recent innovation in the oil and gas industry.
Incorrect. The concept of recovering and reusing gas lift gas has been around for a while.
Scenario: An oil well uses 10,000 cubic feet of gas for lift purposes per day. 80% of this gas is successfully recovered and reused.
Task:
Exercise Correction:
1. **Gas recovered daily:** 10,000 cubic feet * 80% = **8,000 cubic feet** 2. **Gas not recovered:** 10,000 cubic feet - 8,000 cubic feet = **2,000 cubic feet** 3. **Environmental Benefits:** Recovering the gas reduces the amount of greenhouse gas emissions released through flaring. It promotes cleaner and more sustainable oil production. 4. **Economic Benefits:** Reusing the gas reduces the need to purchase additional gas for lift purposes, leading to significant cost savings. It also enhances overall production efficiency and optimizes resource utilization.
