BG Group has completed drilling at an appraisal well in the BM-S-11 concession, off-shore Brazil, with good quality oil samples encountered. The results confirm the westerly extension of the Iara accumulation in the pre-salt Santos Basin and demonstrate the high potential of the pre-salt reservoirs within that area.

The BRSA-1032-RJS well, informally known as Iara West, is located 223 kilometres offshore Rio de Janeiro and approximately nine kilometres from the Iara discovery well in a water depth of 2 150 metres. It encountered good quality oil (21° to 26° API, and within the anticipated range) in the pre-salt carbonate reservoirs at a depth of 5 430 metres.
