OGX Petróleo e Gás Participações S.A. (OGX), reports the presence of hydrocarbons in the Eocene section of well 1-OGX-25-RJS and provided additional information concerning the previously announced discovery in the Albian-Cenomanian section of this well, which is located the BM-C-39 block, in the shallow waters of the Campos Basin. OGX holds a 100% working interest in this block.

Subsequent to the provision of information to the market on December 8, 2010, the drilling of well OGX-25 proceeded, reaching carbonate reservoirs in the Albian-Cenomanian section, and allowing the identification of a total column of approximately 198 meters and total net pay of around 145 meters in this section, as compared to the 125 meters of column and 116 meters of net pay previously announced.

Moreover, new studies, which included logging and cable tests, also permitted the identification of hydrocarbons in sandstone reservoirs in the Eocene section, specifically a gas accumulation with a column of approximately 16 meters and net pay of around 8 meters.

It should be noted that the name of well 1-OGX-25-RJS has changed to 6-OGX-27P-RJS with the drilling of the Albian section. Its drilling will continue until a total estimated depth of 3,100 meters. This well is located in the BM-C-39 block at about 94 kilometers off the coast of the state of Rio de Janeiro at a water depth of approximately 105 meters. The rig, Pride Venezuela, initiated drilling activities there on November 14, 2010.
