| Orignal Description:Per NRC Report: The caller reported a release of an unknown amount of natural gas from an underground well into the atmosphere at the incident location. The cause of the release is due to the tubing blowing out of the well during installation of the tubing. The caller believes there was a build up of pressure in the well that caused the release, and it is believed to be due to equipment failure. There is a plug in the well that is used to prevent build-up, and they believe the plug failed. Remedial Actions: Wellhead is isolated.

THE TEMPORARY LOSS OF WELL CONTROL HAS BEEN DETERMINED TO BE DUE TO A LEAKING PACKING PLUG WHICH CAUSED PRESSURES TO RISE, CAUSING THE TUBING TO EJECT FROM THE BOP STACK.
