Banda East Appraisal Well Offshore Mauritania Reaches Total Depth

Roc Oil (Mauritania) Company, a wholly owned subsidiary of ROC, advised that on November 10, 2008, the Banda East-1B appraisal well reached a total depth of 2,716 mBRT, and acquisition of wireline data has been completed.

The preliminary results of the wireline logging, Modular Dynamic Tester (MDT) pressure testing and sampling indicate that Banda East-1B intersected an 86 meter gross gas column, with 22 meters (26%) net gas pay and a 19 meters gross oil column, with 7 meters net oil pay (37%). The fluid contacts were in line with the pre-drill expectations. 

The Banda Oil and Gas Field is in approximately 300 meters of water depth and spans PSC Area A and PSC Area B.  The forward plan is to run the final casing and prepare for gas deliverability testing. There is no plan to test the oil leg at this time.
