To date, an oil column of approximately 12mt was encountered in carbonate reservoirs in the Albian section of well OGX-18, also known as Inga.
The company said that the well was in a hydrocarbon zone when drilling was interrupted due to sampling. It will resume drilling in order to determine the total column and net pay.
Additionally in the Santonian section, high porosity sands with hydrocarbons were encountered. The drilling of well OGX-18 is still in progress and is expected to continue to a maximum final depth of approximately 2,800mt.
OGX holds a 100% working interest in this block.
Paulo Mendonca, general executive officer of OGX, said: “The OGX-18 well is located 2km away from OGX-14, the Pero prospect. The proximity of these discoveries, combined with the fact that the Albian section of this well is structurally 56mt higher than at OGX-14, points to a potentially superior column than the one already encountered in this block.”
The OGX-18 well is situated approximately 95km off the coast of the state of Rio de Janeiro at a water depth of approximately 105mt. The rig, Ocean Lexington, initiated drilling activities there on July 29, 2010.
