HOUSTON, Feb. 25 -- Petroleo Brazileiro SA (Petrobras) commenced on Feb. 23 an extended well test on the Tracaja presalt reservoir, via well 6-MLL-70, which is in the Campos basin's Marlin Leste field, 124 km off Rio de Janeiro.
Petrobras connected Well 6-MLL-70, which made the oil discovery at a 4,442-m depth in September 2010, to the P-53 floating production, storage, and offloading vessel that also handles production from other wells in the Marlin Leste field that produce oil from non presalt reservoirs.
Initial flow from Well-6-MML-70 was 23,300 b/d.
In December 2010, Petrobras began a similar test at Carimbe also in the presalt cluster in the Caratinga area.
Petrobras submitted the discovery assessment plan for Tracaja to the National Petroleum Agency in 2010. The plan calls for the drilling one or two wells for delineating the accumulation.
In addition to Tracaja and Carimbe, Petrobras has discovered oil in other Campos basin presalt areas and will start an extended well test at Brava (Marlim concession), Aruana, and Oliva (exploration Block BM-C-36) in 2011.
In the northern portion of the Campos basin, off the coast of Espirito Santo, Petrobras has been producing presalt oil from Parque das Baleias since August 2008.
