Rockhopper Posts Analysis of Sea Lion Oil

Rockhopper has updated the analysis of its Sea Lion prospect in the North Falkland Basin. The 14/10-2 well, drilled to a depth of 9,003 feet (2,744 meters), and following completion of final logging, was suspended for future testing. Rockhopper will test the well soon and test equipment is currently being mobilized. The well penetrated a regional seal between 7,382 feet (2,250 meters) and 7,789 feet (2,374 meters). Based on data, it appears that all sands encountered beneath this regional seal are charged with oil and no oil water contacts were encountered. The top oil sand was encountered at 7,789 feet (2,374 meters), and the base of the lowest oil sand level was encountered at 8,501 feet (2,591 meters). The vertical oil column is about 712 feet (217 meters) with a total net pay of 174 feet (53 meters) in seven identified pay zones. The thickest zone is approximately 30 meters gross. Pressure data suggest the possibility of two separate oil columns, but this will be confirmed by a full well test. The main Sea Lion fan has a net pay interval of 115 feet (35 meters), and additional underlying sands have a net pay totaling 59 feet (18 meters).
