OGX discovers hydrocarbons with Belem well in the Santos Basin offshore Brazil

By Phaedra Friend Troy

Private Brazilian independent OGX Petroleo e Gas Participacoes S.A. has discovered a large hydrocarbon structure in the Albian secion of its Belem exploration well, 1-OGX-17A-RJS, located on Block BM-S-56 in the shallow waters of the Santos Basin offshore Brazil.

“This discovery of gas and, possibly, condensate in well OGX-17 reveals the existence of a new Albian play with limestone and sucrose dolomites in our blocks in the Santos Basin,” said Paulo Mendoca, general executive officer for OGX. ‘Using the information previously obtained through the drilling of well OGX-12, we were able to recalibrate our geological model, thereby gaining additional technical insight and momentum in the pursuit of a new cycle of discoveries.”

Spud on July 22, 2010 by Diamond Offshore’s Ocean Star semisubmersible drilling rig, the OGX-17 well is located about 50 miles (85 kilometers) from the shore in waters measuring 445 feet (135 meters) deep.

The Belem discovery well transected an oil column measuring about 640 feet (195 meters), with about 140 feet (43 meters) of net pay, in carbonate reservoirs in the Albian section. Drilling continues on the well to a target depth of 19,030 feet (5,800 meters) total measured depth.

OGX wholly owns and operates Block BM-S-56.
