OGX Continues Positive Exploratory Campaign in Brazil
Since last year OGX Petróleo e Gás has been having excellent results in its exploratory campaign in the Campos Basin.
In well OGX-10, the Hawaii prospect, an oil column of approximately 110 meters and net pay of approximately 40 meters was identified in the carbonate reservoirs of the Aptian section. The well is in its final stage of log analysis. Therefore the rig, Sea Explorer, provided by Pride International, has been moved to well OGX-7A, the Huna prospect, in order to conduct additional tests.
Regarding well OGX-13, the second appraisal well for the Vesuvio accumulation, a net pay of approximately 10 meters was encountered in sandstone reservoirs in the Eocene section. Preliminary information indicates that this well was drilled in one of the structure’s boundaries, making an important contribution towards delineating of the Vesuvio accumulation. Drilling activities have been concluded at OGX-13. As a result, the rig Ocean Lexington, provided by Diamond Offshore, has been moved to the Peró prospect, located in the block BM-C-40.
The drilling of well OGX-10, situated approximately 79 kilometers off the coast of the state of Rio de Janeiro at a water depth of approximately 158 meters, commenced on March 2, 2010. At OGX-13, situated approximately 87 kilometers off the coast of the state of Rio de Janeiro at a water depth of approximately 138 meters, drilling started on May 5, 2010.
“The discovery of liquid hydrocarbons in sandstone reservoirs presenting high permo-porosity indicates an even higher attractiveness to the project than previously anticipated”, commented Paulo Mendonça, General Executive Officer of OGX.
Following the announcement released on May 24, 2010, mentioning evidence of hydrocarbons, gas and condensate in the Santonian section of well OGX-11D, new studies including logging tests, lateral core sampling, pre-tests and a cable test have been conducted, which 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 180 meters from 42 meters and 75 meters from 34 meters respectively, exhibiting excellent levels of permo-porosity. The liquid hydrocarbons encountered are of high quality, with an API of approximately 41°. 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 104 kilometers off the coast at a water depth of approximately 170 meters. The rig, Ocean Quest, provided by Diamond Offshore, initiated drilling activities on April 9, 2010. OGX also holds a 100% working interest in this block.
