• The incident happened during the completions process when transitioning from installing a tubing hanger to installing an adapter flange lower master valve.
• Our preliminary assessment indicates that the incident was caused by a failure of wellhead equipment at the surface and was not related to fracking or downhole operations. While our thorough root cause analysis is ongoing, Chevron has installed a secondary barrier downhole during new tubing installations to mitigate against reoccurrence.
• A root cause analysis into the precise causes of the incident is nearing completion. We will share the findings in accordance with regulatory agencies’ requirements.

This took place during completions, and not during fracking. There was no pipeline failure. Chevron will communicate its findings to relevant agencies upon completion of its investigation.
