Chevron Corp., Houston, Texas, has completed and released a root cause analysis of the Bishop well incident that happened near Galeton, Colorado, in April, saying equipment assembly errors and inadequate fluid barriers contributed to the blowout.<\/p>\n

The uncontrolled release lasted five days before it was contained on April 10. As the blowout unfolded, about a dozen families in the area were evacuated. Some residents have yet to return to their homes.<\/p>\n

Condensate and crude oil spewed onto surrounding properties, and cleanup efforts have involved environmental testing and remediation. Cleanup efforts are expected to last until 2030.<\/p>\n

According to Chevron, on April 6, a wellhead technician contractor was in the process of installing a production tree on a well at the Bishop Well pad when a loss of containment occurred. The incident resulted in the release of fluids, which were made up of gas, crude oil and mostly water, according to the report.<\/p>\n

The technician was struck by the production tree as it fell to the ground, which resulted in a leg fracture, the report says.<\/p>\n

The investigation identified these as the primary root causes of the incident:<\/p>\n
