Exercise: Collapsing in Production Operations

Scenario: You are a production engineer responsible for a well that has experienced a significant decline in production. Analysis indicates a potential wellbore collapse.

Task:

  1. List three potential causes for wellbore collapse in this situation.
  2. Identify two key indicators that would confirm your suspicion of wellbore collapse.
  3. Outline a short-term plan to address the situation and prevent further production decline.

Exercise Correction

**Potential Causes:** 1. **Corrosion:** Corrosion of the wellbore casing can weaken the structure, leading to collapse. 2. **Formation Collapse:** Changes in reservoir pressure due to production can lead to instability in the surrounding rock, causing the wellbore to collapse inwards. 3. **Cement Failure:** Poorly-placed or insufficient cement can leave the casing vulnerable to collapse, especially under high pressure. **Key Indicators:** 1. **Production Decline:** A sudden or gradual decline in production is a strong indicator of a potential problem. 2. **Fluid Loss:** The appearance of fluid losses to the formation or changes in the fluid flow rate might indicate a breach in the wellbore. **Short-Term Plan:** 1. **Production Shutdown:** Temporarily shut down production to minimize further pressure changes and potential damage. 2. **Wellbore Logging:** Conduct a comprehensive wellbore logging program to assess the extent of the damage and identify the specific cause. 3. **Wellbore Repair:** Based on the logging results, develop a plan to repair or replace the damaged casing.
