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.”
