Capitaine-1A Exploration Well
The Stena Tay rig drilled the 12-1/4 inch hole to 2718 meters where 9-5/8 inch casing was set. At midnight on November 1st the rig was preparing to run a casing hanger seal assembly prior to drilling ahead in 8-1/2 inch hole to the planned total depth of approximately 3125 meters.

All reported drilling depths are referenced to the rig rotary table.

Wells are expected to be drilled in three production sharing contract areas during the campaign."

Dr John Doran, Chief Executive Officer of ROC commented that:

"ROC believes that it is now likely that the Mauritanian Government will exercise its entitlement to acquire a 12% interest in the Chinguetti Field Development on a prorata basis from all current Chinguetti participants prior to that entitlement lapsing on November 20, 2004. In the event that the Government does exercise its right in this respect it will be responsible for its share of development and past exploration costs associated with the Chinguetti Oil Field."
