[{"type":"text","content":"\n \nRNS Number : 6329H Rockhopper Exploration plc 01 June 2011 \n\nEmbargoed: 0700hrs 1 June 2011\n \nRockhopper Exploration plc\n(\"Rockhopper\" or the \"Company\")\n \n14/10-5 Appraisal well update\n \nRockhopper Exploration, the North Falkland Basin oil and gas exploration company, is pleased to provide the following update on the 14/10-5 appraisal well:\n \n· Significant reservoir package and hydrocarbon column encountered\n· Wireline log analysis indicates 93.5m (306 feet) net pay in good quality reservoir\n· Average porosity greater than 20%\n· Average permeability of 100-200 millidarcies (mD) and up to 1,000mD\n· 79m net pay in main fan complex\n· 14.5m net pay in lower fan complex\n· No oil water contact observed \n· Rockhopper now intends to test the well\n \n14/10-5 was drilled 600m north of the 14/10-2 discovery well to a total depth of 2,726m (drilled depth) and was the second appraisal well on the Sea Lion feature.\n \nThe well was designed to appraise the Sea Lion main fan reservoir and investigate hydrocarbon column and reservoir distribution.\n \nThe well has been highly successful, proving a very thick, high quality reservoir package and a substantial oil column. The geological prognosis once again came in very close to prediction.\n \nThe Sea Lion reservoir sands were encountered 22m updip from the 14/10-2 discovery well at a depth of 2,378m (drilled depth). A total reservoir package of 110m (360 feet) comprising one main sand and three thinner sands was encountered with a net to gross of 91% in the main sand and 25-80% in the lower sands. The gross oil column in the main Sea Lion fan is now 125m (410 feet). MDT pressures confirm oil gradients throughout all sands.\n \nWireline logging indicates that reservoir quality is good, with average porosity of greater than 20% and average permeabilities of 100-200mD.\n \n79m (259 feet) of net pay has been encountered in the main fan complex with a net to gross of 91%. 14.5m (47 feet) of pay has been encountered in the lower fan complex with a net to gross of 25-80%.
