Petrobras Confirms Continuity of Accumulation in Guara Area

Petrobras has completed drilling of the second extension well in Guará area, 3-SPS-82A (3-BRSA-923A-SPS), located in the Santos Basin pre-salt.

Informally known as Guará Sul (South Guará), the well was drilled 5.7 km south of wildcat discovery well (1-SPS-55). In a water depth of 2,156 m, Guará Sul is located 315 km off the coast of the state of São Paulo. Including the wildcat well, this is the third well in the Guará area.

Preliminary analyses confirm satisfactory conditions of the reservoir and its lateral continuity. The monitoring of pressures compared to those from the discovery well, currently undergoing Extended Well Test (EWT), verified the hydraulic communication of the reservoir between both wells. This scenario indicates a good perspective of production for this accumulation.

Cable test in the pre-salt reservoirs demonstrated the presence of light oil around 27º API. Formation tests still have to be executed to assess the reservoir's productivity.

Petrobras is the operator of the consortium for the exploration of block BM-S-09 (45%), in partnership with the BG Group (30%) and Repsol Sinopec Brasil (25%). The consortium gives continuity to the activities foreseen in the Guará Evaluation Plan.
