OGX-3 formation test indicates 3,000 b/d potential

Offshore staff

HOUSTON – A formation test recently completed at the OGX-3 well in Brazil suggests production potential of some 3,000 b/d, according to operator OGX.

The cased hole drillstem test at the well 1-OGX-3-RJS in the BM-C-41 block of the southern Campos basin, also showed good quality oil estimated between 19° and 20° API, OGX says. The OGX-3 well was drilled to a final depth of 4,084 m (13,398 ft), hitting pay in carbonate reservoirs of the Albian, Aptian, and Barremian sections as announced in December, 2009. Based on the final well information combined with the 3D seismic data interpretation, OGX estimates recoverable oil volume for all reservoirs of between 500 and 900 Mbbl.

Upon reaching target depth, the 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, with an eye toward taking the well into production.
The test data, pressures, and permo-porosity conditions confirm the potential production of 3,000 b/d of petroleum in a 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. Static pressures measured are normal with no signs of depletion. 

Sea Explorer, the rig used at OGX-3, will be mobilized to the next location, the Hawaii prospect in the BM-C-42 block, also in the shallow waters of the southern part of the Campos basin, OGX says. Drilling is scheduled to begin later this month.
