Production optimisation specialist EnproSubsea has completed another two successful subsea hydraulic intervention campaigns for two operators in West Africa
Operations were conducted from a single multi-services support vessel, which was mobilised out of Takoradi in Ghana.
The first of the two campaigns saw Enpro’s Flow Intervention Services (FIS) team deliver scale squeeze operations on five separate subsea wells via a modified choke insert in 1800 m (6,000 ft) water depth. The second campaign utilised the same vessel and hardware and included acid stimulation operations via a hot stab connection onto a further five wells at 1300 m (4,200 ft), for a different operator.
Steve Robb, Enpro Subsea operations director said, “All activities, including mobilisation, deployment, subsea operations, demobilisation and maintenance are executed by the Enpro team. With the success of 19 FIS operations in West Africa under our belt, we are now well placed to deliver these services to others in the region and beyond looking for a low-cost hydraulic intervention solution.”
Following the completion of the 10,000psi FIS system in Ghana, Enpro showcased its second-generation 15,000psi version at Offshore Europe 2019 in Aberdeen before sending it to the Gulf of Mexico region for further trials. Rated for 3,048 m (10,000 ft) water depth, the company stated that it encompasses additional functionality and enhanced safety features. In addition to hydraulic intervention of the wells, the new system is configurable for other subsea treatments, including hydrate remediation, flow line flushing and well kill.
Ian Donald, Enpro Subsea CEO commented, “We have now established Enpro Subsea Ghana Limited, a local joint venture, which will allow us to expand operations in the region, continue to support existing and new clients, and maximise the local content of these projects.”
