Instructions: Choose the best answer for each question.
1. What is the primary purpose of injection gas in oil and gas production?
a) To increase the viscosity of produced fluids. b) To decrease the temperature of the reservoir. c) To maintain or enhance reservoir pressure and well performance. d) To prevent the formation of gas hydrates.
c) To maintain or enhance reservoir pressure and well performance.
2. Which of the following is NOT a type of gas commonly used for injection?
a) Produced gas from the reservoir. b) Natural gas. c) Nitrogen. d) Carbon dioxide.
d) Carbon dioxide.
3. How does injection gas contribute to reservoir pressure maintenance?
a) By removing dissolved gases from the reservoir. b) By creating a vacuum in the reservoir. c) By acting as a pressure support system, expanding pore space and pushing fluids towards the well. d) By reducing the density of the reservoir fluids.
c) By acting as a pressure support system, expanding pore space and pushing fluids towards the well.
4. What is the main benefit of gas lift operations?
a) To increase the viscosity of produced fluids. b) To enhance flow rates and improve well performance, particularly in wells with high water production or high-viscosity fluids. c) To decrease the temperature of the reservoir. d) To prevent the formation of gas hydrates.
b) To enhance flow rates and improve well performance, particularly in wells with high water production or high-viscosity fluids.
5. What is a critical consideration when choosing injection gas?
a) The color of the gas. b) The odor of the gas. c) The chemical composition and purity of the gas. d) The availability of the gas at a low price.
c) The chemical composition and purity of the gas.
Scenario: An oil well is experiencing declining production due to falling reservoir pressure. To address this, the operators are considering injecting gas into the reservoir to maintain pressure and enhance production.
