BG Group has completed a drill stem test on the Guara Norte well (3-SPS-69) in block BM-S-9 in the Santos Basin, offshore Brazil.

The company owns a 30% interest in the BM-S-9 concession, along with Petrobas and Repsol, which have 45% and 25% stakes, respectively.

The test confirmed a productivity of 6,000 barrels of oil per day of light oil (approximately 30° API), with flow rates constrained by test facility capacity.

The well was drilled to a depth of 2,118m, approximately 305km off the coast of the state of Sao Paulo and 15km north-east of the original discovery well.

The Guara Norte well is estimated to have a production potential of 50,000bopd.
