Wireline testing confirmed the presence of light oil at approximately 30° API. The information obtained from this well and other wells already drilled, suggests the estimate of a potential five to eight billion barrels of recoverable light oil and natural gas from the Tupi pre-salt reservoirs.
The Tupi Alto well, drilled by partners Petrobras (65%, operator), BG Group (25%) and Galp (10%), is located in the Tupi evaluation area in a water depth of 2 111mt, approximately 275km from Rio de Janeiro.
Drilling on Tupi Alto has been completed and drill stem tests to evaluate reservoir productivity will be conducted in due course.
Frank Chapman, chief executive of BG, said: “The Tupi Alto well, in conjunction with the trend seen in previous Tupi appraisal wells, has confirmed excellent reservoir properties over a wide area in the Tupi field.
“Appraisal results continue to confirm the reservoir models in Tupi, Iracema and Guara by giving better definition in crestal areas and on the flanks of the fields.”
