Brazilian oil and gas firm OGX Petroleo e Gas Participacoes has discovered hydrocarbons in the Albian section of well 1-OGX-28D-RJS in the Campos Basin, offshore Brazil.

The well is located in the BM-C-41 block and is situated about 80km off the coast of the state of Rio de Janeiro at a water depth of approximately 126m in the shallow waters of the Campos Basin.

The company said that it has identified a total column of about 52m with approximately 24m of net pay in carbonate reservoirs in the Albian section.

The drilling of the OGX-28D well, a prospect known as Illimani, is expected to reach an estimated final depth of 3,700m.

OGX general executive officer Paulo Mendonca said that this discovery reinforces the significant extent of the carbonate platform in the Albian section found in the south of the Campos basin.

"The year of 2011 will see the continuation of the exploratory campaign, with drilling in new frontiers and important advances in the delineation of our discoveries, as well as initial production," Mendonca said.

OGX holds a 100% working interest in this block.
