Well Kill

and Emergency Support

We were tasked to perform a well integrity assessment to gain an understanding of the well’s current risk profile.

What did we do?

Data analysis: Compared well design reports and production data to NORSOK D-010 requirements using an in-house well integrity tool to understand the current risk profile of the well

Developed a remedial system: Highlighted the projected benefits from remedial actions identified through analysis in a traffic light system. The traffic light system also created the basis for a leak path analysis, which was performed by well kill specialists to determine if additional resources were required to kill the well in the most likely well control incident

Risk assessment: Performed an overall risk assessment to lower the risk level to As Low As Reasonably Practicable (ALARP)

Delivered a close-out report: Suggested new operating procedures and recommended practices to lower the risk and ensure continued safe operating conditions

The result

Based on the well integrity analysis and recommendations provided, the operator was able to make an informed decision to keep the well in operation whilst working to adhere to the suggested guidelines.

This resulted in the operator achieving their annual production target.

Why we were contracted?

The client noticed abnormal well pressure behavior in a subsea well and wanted to determine if it was safe to continue operations.

We were contacted to give advice on further action to rectify the situation by conducting a technical investigation.
