ABERDEEN, UK – Enpro Subsea has completed two subsea hydraulic intervention campaigns for two operators in West Africa.
Operations were conducted from a multi services support vessel, which was mobilized out of Takoradi in Ghana.
The first of the two campaigns saw the company’s flow intervention services (FIS) team deliver scale squeeze operations on five subsea wells via a modified choke insert in 1,800 m (5,905 ft) water depth.
The second campaign used the same vessel and hardware and included acid stimulation operations via a hot stab connection onto five more wells at 1,300 m (4,265 ft), for a different operator.
In the last two years, the FIS technology has been deployed in 19 wells in the region, with zero accidents or loss time incidents.
The FIS hydraulic intervention system provides the capability to transfer the stimulation treatments from a vessel’s pumps to the subsea well via an integrated deployment and subsea safety system – the Subsea Safety Module (SSM) – which sits on the seabed and connects to both the downline and adjacent XT or manifold via a composite pipeline.
