Petroleo Brasileiro SA (Petrobras) has discovered a natural gas accumulation in the post-salt Espirito Santo basin, 72 km offshore Brazil’s Espirito Santo state.
The Tanganika well, formally known by Petrobras as 3-ESS-222 and Brazil’s National Petroleum Agency as 3-BRSA-1259-ESS, was drilled in the Malombe discovery evaluation plan (PAD) in 1,043 m of water, reaching a total depth of 2,996 m. The Malombe discovery was made by the consortium in 2011 (OGJ Online, Nov. 4, 2011).
The Tanganika discovery was confirmed through logging carried out in reservoirs at 2,880 m. Petrobras says it will proceed with plans to evaluate the discovery through a formation test.
Petrobras operates the two-company consortium with 89.89% interest. Repsol Sinopec holds the remaining 11.11%.
