Petrobras Makes Substantial Discovery in Santos Basin

The Jupiter well in ultradeep Santos basin waters has large natural gas and condensate reserves, said Petrobras in a press release issued Jan. 21. Petrobras made the discovery in the presalt layers of the formation, some 5,100 meters below the ground's surface.

As part of a consortium, Petrobras explored block BM-S-24 located in the Santos basin area along with Galp Energia. The "pioneer well" was drilled by Diamond Offshore's Ocean Clipper drillship to a total depth of 5,252 meters, 290 kilometers offshore Brazil and 37 kilometers east of the Tupi area. The well has been drilled in a water depth of 2,187 meters.

Petrobras claims that the hydrocarbon-bearing rock is estimated to be more than 120 meters thick. The area dimensions of the reservoir are presumed to be similar in size to that of the Tupi discovery.

The consortium will proceed with the required activities and make the investments necessary not only to check this new field’s dimensions, but also to determine the natural gas and condensate-bearing reservoir characteristics," said Petrobras in the issued press release. "A Discovery Assessment Plan is being elaborated and will be forwarded to the NPA as provided for in the Concession Agreement."
