Aberdeen-based well management firm Zenith Energy has successfully completed the plug and abandonment of a platform well on the Ombrina Mare field offshore Italy for Rockhopper Exploration.
The project was the firm's first offshore well management project. Zenith Energy completed the project using the Atwood Beacon jackup, a rig of opportunity.
The operation involved re-entry to the existing well, bullheading operations, removal of completion, casing and wellhead equipment, and the setting of permanent barrier cement plugs.
Zenith Energy’s operations director, Chris Collie, said: "This project marks a significant milestone for Zenith. We have safely and efficiently completed our first offshore well management project, which was planned and executed by a small but highly experienced team within a five-month period. This enabled our client to take advantage of a rig of opportunity and permanently abandon their well at significant cost savings due to current market rates.
“Our team planned and executed operations within AFE and the project involved all operations that you would typically expect in a well abandonment - slick line, wireline, Xmas tree removal, cementing, cutting and pulling casing and removal of topside wellhead equipment in a well with high concentrations of H2S and A annulus pressure issues. This showcases our ability to provide quality well engineering and management for offshore projects, in a country with strict regulatory regime and challenging working environments."
