Apr. 2012 - OGX has identified the presence of hydrocarbons in carbonate reservoirs in the Albian section of well 1-OGX-79-RJS in Block BM-C-39 in the shallow waters of the Campos Basin. A hydrocarbon column of approximately 492 feet (150 meters) was encountered in carbonate reservoirs of the Albian section with about 210 feet (64 meters) of net pay. The drilling of well OGX-79, known as Itacoatiara, was concluded at a final depth of 6,660 feet (2,030 meters). OGX said the Itacoatiara accumulation (OGX-79) expands the Waikiki Complex, and together with the Tubarao Martelo field and Pero and Inga accumulations. Drill stem tests will be conducted to obtain more information on this accumulation. The proximity of Itacoatiara accumulation to the other Waikiki Complex accumulations, a distance of about 2 miles (4 kilometers), facilitates their integration and development, in addition to accelerating the monetization of the discovered resources. The ENSCO 5004 (mid-water semisub) drilled the well in a water depth of 335 feet (102 meters).
