BG Group (LON:BG) announced that the ninth Tupi well, 3-RJS-678 and informally known as Tupi SW, was successful.
The well was drilled at a water depth of 2,152 metres, approximately 295 kilometres off the coast of Rio de Janeiro State, and 11 kilometres southeast of well 3-BRSA-496, where drill stem testing is being conducted in pre-salt reservoirs.
Oil samples taken during wireline tests in well 3-RJS-678 confirmed the presence of a light oil accumulation with approximately 28 degree API. The well encountered a 128-metre reservoir section and located the oil/water contact in the Tupi accumulation at the deepest of the potential depths previously being considered, further reducing uncertainty in estimating hydrocarbon volumes for the Tupi area.
BG Group is active in more than 25 countries on five continents and has a broad portfolio of exploration and production, Liquefied Natural Gas (LNG), transmission and distribution and power generation business interests.
