Rockhopper Exploration has discovered a significant oil column in appraisal well 14/10-4 in the Falkland Islands. Well 14/10-4 uncovered 108 feet (33 meters) of net pay in good quality reservoir with 20% average porosity.
The well was drilled to a total depth of 9,190 feet (2,801 meters), finding the oil-water contact level at 8,127 feet (2,477 meters). The well was spudded last month and lies just over 1 mile (2 kilometers) away from 14/10-2 discovery well. It is designed to investigate just how deep the reservoir is.
The top of the Sea Lion reservoir sands were encountered 216 feet (66 meters) downdip from the 14/10-2 discovery well. A total reservoir package of 351 feet (107 meters), comprising four main sands was encountered with a net to gross of 76%.
Ninety-eight feet (Thirty meters) of net pay has been encountered in the upper of the four sands, representing the main Sea Lion southern fan. The gross oil column now proven in the main Sea Lion southern fan is 341 feet (104 meters).
Rockhopper believe the results of this successful first appraisal well will significantly increase the contingent P90 volume for this oil discovery. The P50 and P10 contingent volumes will be defined as the appraisal program progresses through the remainder of 2011.
The well will now by plugged and abandoned as planned. Following this well, Rockhopper will commence work on development planning for the Sea Lion discovery.
