Instructions: Choose the best answer for each question.
1. What is the primary purpose of well completion?
a) To drill the initial hole in the ground.
Incorrect. Drilling the initial hole is part of the drilling process, not well completion.
Correct. Well completion is the process that makes a well ready to produce oil or gas.
Incorrect. Transporting hydrocarbons is a separate process that occurs after extraction.
Incorrect. Identifying potential deposits is done through exploration and geological surveys.
2. Which of these is NOT a key step involved in well completion?
a) Running casing
Incorrect. Running casing is a fundamental step in well completion.
Incorrect. Production tubing is essential for transporting hydrocarbons to the surface.
Incorrect. Packers are important for isolating and controlling different zones within the well.
Correct. Economic evaluation is done before drilling, not during well completion.
3. What is the primary advantage of a multi-zone completion?
a) It simplifies the well design.
Incorrect. Multi-zone completion typically involves more complex well designs.
Incorrect. Wellbore collapse is addressed by casing and other structural elements.
Correct. Multi-zone completion optimizes production by accessing different zones.
Incorrect. Stimulation techniques are often used regardless of the completion type.
4. How does well completion contribute to environmental protection?
a) By minimizing the use of water in drilling operations.
Incorrect. Water usage is primarily related to drilling, not well completion.
Correct. Well completion techniques help prevent leaks and spills, protecting the environment.
Incorrect. Greenhouse gas emissions are primarily related to production and processing, not well completion itself.
Incorrect. Well completion is related to oil and gas extraction, not renewable energy.
5. Which of the following is NOT a benefit of a well-designed completion?
a) Enhanced flow rates
Incorrect. A good completion maximizes flow rates and production.
Incorrect. A well-completed well is less likely to experience operational problems.
Correct. A well-designed completion aims to optimize production, minimizing costs.
Incorrect. Proper completion enhances well longevity.
Scenario: An oil well has been drilled to a depth of 10,000 feet. The reservoir contains three distinct oil-bearing layers at depths of 5,000 feet, 7,000 feet, and 9,000 feet.
Task: Design a well completion strategy that allows for the production of oil from all three layers simultaneously. Explain your choices and justify your reasoning.
A multi-zone completion would be the most appropriate strategy for this scenario. Here's why:
Benefits:
A multi-zone completion is a more complex design compared to a single-zone completion, but it offers significant advantages in terms of production optimization, reservoir management, and overall efficiency.
