Rio-based OGX claims that its BM-C-43 block, located in the shallow waters of the Campos Basin, may hold between 500 million and 1.5 billion barrels, based on well information and seismic data. The company owns all of the block, according to its Web site.
The company earlier this month also said it found signs of crude in the BM-S-29 block, in the Santos Basin off the coast of Sao Paulo state.
