Exercise: Production Optimization
Scenario: You are a production engineer at an oil and gas company. You notice a decline in production from a particular well. After analyzing the data, you realize that the wellhead pressure is significantly lower than expected.
Task:
- Identify two possible reasons for the decreased wellhead pressure.
- Describe two adjustments you could make to address the issue and increase production.
- Explain why these adjustments are likely to improve production.
Exercice Correction
**1. Possible reasons for decreased wellhead pressure:**
- **Wellbore damage:** A blockage or restriction in the wellbore, perhaps due to sand production or scale buildup.
- **Depletion of reservoir pressure:** Natural decline in reservoir pressure as oil is extracted, leading to reduced flow.
**2. Adjustments to increase production:**- **Well stimulation:** Perform a stimulation treatment, such as hydraulic fracturing or acidizing, to increase reservoir permeability and improve flow.
- **Artificial lift:** Install an artificial lift system, like an electric submersible pump (ESP), to assist in bringing oil to the surface.
**3. Why these adjustments are likely to improve production:**- **Well stimulation:** Removing blockages or increasing reservoir permeability will allow more oil to flow into the wellbore, increasing production.
- **Artificial lift:** Installing an ESP will provide additional lift to overcome the decreased wellhead pressure, bringing more oil to the surface.
