Gas flowing from deepwater GTA development offshore northwest Africa
bp has produced first gas from the Greater Tortue Ahmeyim (GTA) Phase 1 LNG development offshore Mauritania and Senegal, according to a Jan. 2 company press release.
The gas is flowing to the FPSO, which should deliver the first cargo of LNG later this quarter, according to partner Kosmos Energy.
Water depths for the development range from shallow to 2,850 m above the reservoirs, 120 km offshore. Phase 1 features a four-well subsea production system.
The FPSO, moored roughly 40 km from the coast, is designed to process more than 500 MMcf/d of gas, with facilities for stripping out the water, condensate and impurities.
Post-treatment, the gas will head through a subsea pipeline to the Golar LNG-owned and operated FLNG Gimi, stationed 10 km offshore behind a concrete breakwater. Here, the gas will undergo cryogenic cooling, liquefaction and storage before being offloaded to LNG carriers for export.
However, some volumes will be set aside for local needs in Mauritania and Senegal. Once the facilities are fully commissioned, bp expects GTA Phase 1 to produce about 2.3 MMmt/year of LNG.
State-owned PETROSEN and SMH are the other co-venturers.
