Multi-PSL team delivers three subsea wells ahead of project scheduleDownload PDF
Deliver a complex three-well P&A program
Halliburton was awarded a multi-services contract from an international oil company (IOC) in the UK sector of the North Sea to provide integrated plug and abandonment (P&A) services for three subsea wells located in a mature field of the UK Continental Shelf (UKCS). The project was estimated to take around three months to complete.
The risks associated with conducting subsea well P&A operations are among the most challenging to undertake, and these risks include:
The Halliburton Project Management (HPM) team was awarded a multi-services contract to provide integrated project management offshore and onshore, along with cementing materials, fluids, cased-hole services (slickline and e-line), plug and packer products, and tubing-conveyed perforating (TCP).
The HPM team worked with the client and other key stakeholders to drive project efficiencies, ensure capturing of lessons learned and opportunities for improvement, and leverage experience from previous projects in order to help foster an ethos of continuous improvement and collaboration, as well as to implement Halliburton technologies and updated industry methodologies.
Successful implementation of the above included:
Days ahead of schedule
Alignment with health, safety, and environmental (HSE) considerations at the worksite drove a “one-team” safety culture offshore. The HPM team’s ability to work closely with the client and rig contractor in order to scope specific solutions was a major contributing factor to the project’s overall success. This team’s performance was excellent throughout, with only 0.21% non-productive time (NPT) recorded across the entire project.
This project proved that the HPM team could deliver integrated services in a tri-party business model – collaborating with the customer and rig contractor on planning, execution, and HSE – to successfully abandon the client’s subsea well stock under fixed-price contractual terms.
