Studies including logging tests, lateral core sampling, pre-tests and a cable test have been conducted that has led to the conclusion that the discovery refers to an accumulation of liquid hydrocarbons with associated gas.
The total oil column and net pay identified in the sandstone reservoirs of the Santonian section have increased to approximately 180mt from 42mt and 75mt from 34mt respectively. The liquid hydrocarbons encountered are of high quality, with an API of approximately 41°, the company said.
The drilling of the well is still in progress and is expected to continue to a final depth of 6,100 meters, targeting deeper objectives.
The well, located in the BM-S-59 block, is situated 104km off the coast at a water depth of approximately 170mt. The rig, Ocean Quest, provided by Diamond Offshore, initiated drilling activities on April 9, 2010. OGX holds a 100% working interest in this block.
Paulo Mendonca, general executive officer of OGX, said: “The discovery of liquid hydrocarbons in sandstone reservoirs presenting high permo-porosity indicates an even higher attractiveness to the project than previously anticipated.”
