WELL-SAFE TO EXECUTE DECOMMISSIONING OF WELLS IN BUCHAN AND HANNAY FIELDS
Repsol Sinopec has awarded a multi-million-pound contract to Aberdeen-based Well-Safe Solutions to execute the decommissioning of all wells in its Buchan and Hannay fields.
The contract is the first fully-inclusive well decommissioning contract of its kind and enables Repsol Sinopec and Well-Safe Solutions to manage efficiencies, knowledge and cost. The schedule control provided as part of this contract enables Well-Safe to deliver its Plug & Abandon (P&A) Club approach helping to deliver a campaign-based approach aligned with the OGA Decommissioning Strategy.
The commercial model represents a step-change from a conventional transactional approach to an outcome-oriented model, empowering the supply chain to deliver the most innovative and efficient solution with a fair shared risk-management philosophy within the contract.
This shift in mind-set has taken considerable time and collaborative effort by both Repsol Sinopec and the supply chain in evolving, concluding and assuring the tender process for this contract.
The contract has been welcomed by OGUK and The Oil & Gas Authority (OGA) as a strong example of collaboration, campaigning and innovation.
José Luis Muñoz, Repsol Sinopec’s Chief Executive Officer, commented today:
“There are 14 subsea wells in the Buchan and Hannay fields that require decommissioning as part of planned activities. We are pleased to appoint the contract for this work to Well-Safe Solutions, who will take a campaign approach to the work, recognising that schedule flexibility is key to driving efficiency.”

The field was discovered in 1974 and first oil was achieved in May 1981. In total, 12 wells have been drilled in the Buchan field: seven production wells; two appraisal wells: one exploration well and two water injection wells.
The Hannay field spans block 20/5c and was discovered in 1996 and commenced production in 2002. The field is located c. 13.5km northwest of the Buchan template in water depth of c. 123m.The Hannay field comprises two production wells which are currently shut-in and disconnected from the flowlines.
The fields were produced via the floating production unit (FPU), Buchan Alpha. Processed hydrocarbons were transported to the Forties Charlie platform via a c. 56.3km export line.
