Aberdeen-based well management firm Zenith Energy has successfully completed the plug and abandonment (P&A) of the Ombrina Mare development well, offshore Italy, for London’s Rockhopper Exploration.
The Atwood Beacon, from Atwood.
Utilizing its experienced well engineering personnel, well delivery process and HSEQ management systems, Zenith completed the project using the Atwood Beacon jackup MODU.
The operation involved re-entry to the existing well situated on an unmanned platform, bullheading operations, removal of completion, casing and wellhead equipment, and the setting of permanent barrier cement plugs.
The project involved 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.
Zenith Energy’s operations director, Chris Collie, said: “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.
Rockhopper Exploration COO, Fiona MacAulay, said: “Zenith provided Rockhopper with the well engineering personnel to plan and manage our well abandonment operation and they have achieved our objectives of permanently abandoning the Ombrina Mare well. They integrated well with the Rockhopper team and provided a first class team of engineers to deliver the project safely and within budget.”
