The company provided well engineering and project management services to operator Rockhopper Exploration, using the jackup Atwood Beacon.
The scope over the five-month program covered re-entering the existing well on the unmanned platform, bullheading operations, removal of completion, casing and wellhead equipment, and setting of permanent barrier cement plugs.
Operations director Chris Collie said: “The project involved all operations that you would typically expect in a well abandonment - slick line, wireline, christmas tree removal, cementing, cutting and pulling casing and removal of topside wellhead equipment in a well with high concentrations of hydrogen sulfide and A annulus pressure issues.”
