The drilling of well OGX-12, also known as Niteroi, reached a total depth of 5,074mt, and encountered carbonate reservoirs in the Albian section with good conditions of permo-porosity, although with an ineffective geological seal, the company said.
In addition, two thin intervals of carbonate reservoirs with indications of hydrocarbons were found in the Aptian and Barremian sections, confirming an active petrolific system.
Paulo Mendonca, general executive officer of OGX, said: “After a highly successful exploratory campaign with announced discoveries in all 14 of our previously drilled wells, the drilling of the Niteroi prospect had as main objective the testing of a new geological model.”
The OGX-12 well, located in the BM-S-57 block, is situated approximately 95km off the coast at a water depth of approximately 150mt. The rig used in this drilling will be moved to the BM-S-56 block and will drill the Belem prospect.
