The OGX-3 well was drilled to a depth of 4,084mt, resulting in the detection of hydrocarbons in carbonate reservoirs of the Albian, Aptian and Barremian sections. Based on the final well information combined with the 3D seismic data interpretation, OGX estimates recoverable oil volume of between 500 and 900 million barrels for all reservoirs.
Upon drilling completion, a Cased Hole Drillstem Test was performed in carbonate reservoirs of the Albian section of well OGX-3, in order to verify the reservoir’s characteristics in dynamic conditions. The test data, pressures and permo-porosity conditions confirm the potential production of 3,000 barrels of petroleum per day in vertical well.
OGX plans to develop this field through horizontal wells and it is estimated that this potential could be increased by up to five times per well, pointing to productivity gains.
OGX said that the test was conclusive, indicating good quality oil, estimated between 19 and 20 degree API. The static pressures measured are normal, with no indication of depletion. This test is for the better understanding of both reservoir and development of future production projects in the region.
Sea Explorer, the rig used at OGX-3, will be mobilized to the next location, the Hawaii prospect, situated in the BM-C-42 block, also in the shallow waters of the southern part of the Campos Basin. The drilling of this well is expected to commence in the mid of February 2010.
