Scenario:
You are an engineer working on an oil and gas production platform. The platform has 10 wells connected to a common manifold. The MFP reading is currently 1500 psi. You notice that the WHFP of one particular well is significantly lower than the others, indicating a potential problem.
Task:
**1. Potential Causes for Low WHFP:** * **Wellbore blockage:** This could be due to sand production, debris, or formation damage. * **Flowline restriction:** A blockage in the flowline connecting the well to the manifold could cause a pressure drop. * **Wellbore pressure depletion:** The well may be nearing the end of its productive life and its pressure has naturally declined. * **Production equipment malfunction:** A problem with the wellhead valve, tubing, or other equipment could be limiting flow. **2. Investigating and Diagnosing the Issue:** * **Check wellhead pressure readings:** Verify the WHFP reading and compare it to historical data. * **Inspect flowline for potential blockages:** Check the flowline visually and run pigging operations to clear any debris. * **Analyze well production history:** Review production logs and look for any trends that suggest declining well performance. * **Run well tests:** Perform flow tests to determine the well's current production capacity and identify any restrictions. * **Analyze reservoir pressure data:** If available, review reservoir pressure data to assess the well's current reservoir pressure and production potential. **3. Possible Solutions:** * **Well stimulation:** Techniques like acidizing or fracturing can improve flow by removing blockages or enhancing permeability in the reservoir. * **Flowline cleaning:** Pigging operations or other methods can be used to remove debris and restore flowline capacity. * **Wellbore repair:** If equipment failure is identified, repair or replacement of the affected components may be necessary. * **Well recompletion:** If the well's productivity is significantly declining, recompletion strategies can be employed to access new reservoir zones or improve flow efficiency.
