LONDON -- Petrobras has completed drilling of appraisal well 3-RJS-666 on the Tupi field in the pre-salt Santos basin.

Operations started in the BM-S-11 appraisal area in January, at a location 12.5 km (7.8 mi) north of the original Tupi discovery well, in 2,115 m(6,939 ft) of water, and 265 km (164 mi) offshore Rio de Janeiro.

The step-out well was designed to test the outer limits of the expected reservoir in the Tupi field. According to partner BG Group, the results of this and other wells drilled previously confirm an estimated recoverable resource of 5-8 Bboe of light oil and natural gas.

Evaluation of the well data continues, as does optimization of field development options. BG says the partners will maintain the activities and investments in the Evaluation Plan approved by the Brazilian National Petroleum Agency (ANP), which include drilling of further wells in the area. Oil and gas production from the first-phase Tupi development is expected by end-2010.
