LUANDA, Angola and HOUSTON -- GE Oil & Gas has completed a subsea equipment upgrade to increase production from the Lobito Tomboco field, offshore Angola.

GE applied VetcoGray technology to retrofit existing subsea trees on the field under a contract with Chevron subsidiary Cabinda Gulf Co. of Angola.

New GE equipment supplied for the project included scale-squeeze inserts for short- and long-term operations, a fluid cap, a choke insert with full functionality with an additional port for chemical injection, and a chemical line with landing skid. The use of a VetcoGray choke interface, a port in the subsea tree, allows choke inserts (the pressure/flow controlling element) to be removed and replaced as required during the life of the field.

The project marks the first time that a retrofit technology has been used in deepwater scale-squeeze, GE says. This type of system has now been extended for deepwater scale squeeze operations up to 1,850 ft (564 m) with further plans to extend the technology to 3,500 ft (1,067 m) in similar projects for the region.
