Narrative
The landowner discovered a leak at little station and contacted the control center. The pipeline was down at this time and the pipeline controller blocked in upstream and downstream and made calls to the field personnel. Our technician responded to the station and discovered the seal on the densitometer pump had failed. He immediately shut the pump down and locked it out. Crews moved to the site with a vacuum truck to the leak affected area, a 3/4 of an acre with a thickness of oil-soaked soil of one (1) inch. Since there was water associated with this leak, it is safe to say at least 30% of the estimated volume of the leak would have been 121 bbls and it was saturated with water prior to oil sock. This resulted in having unrecoverable crude oil of 85 bbls. Remediation will take place. Update 1/26/2012 - received final cost associated with this leak. All remediation and clean up is finished. Densitometer pump was disconnected and not replaced at this time. Will replace the densitometer pump when needed on the pipeline. Nb
