Scenario: You are an engineer working on a perforating operation. Your MWPT data reveals that the perforating gun pressure is consistently lower than the expected value.
Task:
**1. Potential Causes:** * **Malfunctioning pressure gauge:** The pressure gauge on the MWPT could be faulty, providing inaccurate readings. * **Low explosive charge pressure:** The pressure of the explosive charges used in the perforating gun could be lower than expected, leading to reduced detonation pressure. **2. Impact on Perforating Operation:** * **Lower perforation quality:** Reduced pressure during detonation might lead to incomplete or poorly formed perforations, impacting the well's productivity. * **Reduced well efficiency:** The incomplete perforations may restrict fluid flow, leading to lower production rates. **3. Actions to Investigate and Address:** * **Verify pressure gauge calibration:** Check the accuracy of the MWPT pressure gauge against a known standard. If the gauge is faulty, replace it with a calibrated one. * **Inspect explosive charges:** Examine the explosive charges for any damage or signs of reduced pressure. If necessary, replace the charges with new ones.
