Roc Oil & Partners Sidetrack Banda Well Offshore Mauritania

04-24-2008

Roc Oil reports that the Banda NW appraisal well located offshore Mauritania had been plugged back to 1,078 mBRT and a sidetrack well, Banda NW ST-1, commenced and drilled to 2,284 mBRT.

Wireline pressure data in Banda NW-1 had indicated penetration of a gas column, but as uncertainty existed concerning the location of fluid contacts, a sidetrack borehole was initiated.

The forward program is to drill the sidetrack to further evaluate the hydrocarbon column in a more favorable structural position. The well is being drilled by the Atwood Hunter semisub.
