The video captures a pump jack well, typically operating under low pressure, suddenly experiencing high-pressure gas from the bottom hole, leading to a blowout and fire.
Possible Causes:
Gas migration from a deeper zone due to casing or tubing failure.
Nearby injection operations increasing pressure unexpectedly.
Undected fault movement or gas cap release.
What Happens Next?
The high-pressure gas rapidly escapes, creating a violent eruption. If an ignition source (electrical spark, friction, or hot engine parts) is nearby, it ignites, causing a fire at the wellhead.
Since pump jacks are for depleted wells, this sudden pressure suggests a serious well control failure requiring immediate emergency response to prevent escalation.
To control the blowout and fire:
- Shut off ignition sources – Stop nearby engines, power, and any heat sources.
- Evacuate personnel – Ensure safety and secure the area.
- Control gas flow – If possible, close wellhead valves or use emergency shut-in equipment.
- Pump heavy mud or kill fluid – If access allows, pump high-density fluid to counter gas pressure.
- Deploy fire suppression – Use water or specialized fire-fighting foam to control flames.
- Call a well control team – Specialists may use blowout preventers (BOPs) or relief wells if needed.
