Technology Driving Upgrade Projects For GE Oil & Gas

Posted on February 3, 2010

GE Oil & Gas has completed a subsea equipment upgrade that is helping to increase production in a deepwater oil field off the coast of Angola. Under a contract with Cabinda Gulf Co. of Angola, a subsidiary of U.S. oil company Chevron, GE’s Drilling & Production business applied the latest VetcoGray technology to retrofit existing subsea trees in the Lobito Tomboco field.

The technology retrofit was conducted to support the first such deepwater scale-squeeze operation intended to reduce the formation of scale on initial equipment and pipeline systems, leading to increased productivity at the field. The project marks the first time that a retrofit technology has been used in deepwater scale-squeeze. This type of system has now been extended for deepwater scale squeeze operations up to 564 m with further plans to extend the technology to 1067 m in similar projects for the region.

GE Oil & Gas has also announced that it will apply advanced compressor technology in an upgrade project to increase the productivity of Krishak Bharati Cooperative Limited’s (KRIBHCO) urea, ammonia and bio-fertilizer manufacturing facility at Hazira in the state of Gujarat, India. Under the terms of the agreement GE will supply nine compressor upgrade packages to be installed across the plant’s three existing CO2 trains.

GE will utilize its latest impeller designs to upgrade the CO2 compressors, enabling them to pump 45% more flow without changing the steam turbine drivers. GE will upgrade the compressor packages without changing the balance-of-plant or the original compressor footprints. The contract, which is scheduled for completion in the first half of 2011, also includes the supply of anti-surge valves and spare rotors.
