Instructions: Choose the best answer for each question.
1. What is the primary purpose of continuous flow gas lift?
a) To increase the pressure at the bottom of the well. b) To inject water into the wellbore to displace oil. c) To reduce the hydrostatic pressure in the wellbore and facilitate oil flow. d) To remove impurities from the produced oil.
The correct answer is **c) To reduce the hydrostatic pressure in the wellbore and facilitate oil flow.**
2. How does continuous flow gas lift achieve its purpose?
a) By injecting high-pressure water into the wellbore. b) By injecting compressed gas into the wellbore, creating a less dense mixture. c) By using electric submersible pumps to lift the oil. d) By using a system of pipes and valves to manually lift the oil.
The correct answer is **b) By injecting compressed gas into the wellbore, creating a less dense mixture.**
3. What is a major advantage of continuous flow gas lift over other artificial lift methods?
a) It requires less maintenance and is more reliable. b) It is the most environmentally friendly option. c) It can be used in wells with very high water cuts. d) It is the cheapest option available.
The correct answer is **a) It requires less maintenance and is more reliable.**
4. Which of the following is NOT a disadvantage of continuous flow gas lift?
a) The need for a reliable source of gas for injection. b) High costs associated with compressing and transporting the gas. c) It requires extensive modifications to the wellbore design. d) It can only be used in wells with low water production rates.
The correct answer is **d) It can only be used in wells with low water production rates.**
5. Continuous flow gas lift is particularly well-suited for:
a) Wells with high reservoir pressures and low water cuts. b) Wells with low reservoir pressures and high water production rates. c) Wells with low gas-oil ratios and high oil viscosity. d) Wells located in areas with abundant electricity for ESPs.
The correct answer is **b) Wells with low reservoir pressures and high water production rates.**
Scenario: You are a production engineer working on an oil well with a low reservoir pressure and high water production rate. You are tasked with choosing the best artificial lift method for this well.
Task:
**1. Suitability of Continuous Flow Gas Lift:**
Continuous flow gas lift is well-suited for this well due to its low reservoir pressure and high water production rate. This method effectively reduces hydrostatic pressure, enabling easier oil flow despite the challenges posed by low pressure and water production. It can handle high water cuts, which is a key requirement in this scenario.
