[{"type":"text","content":"\n Gold Oil PLC\n04 September 2006\n\n\nFor Immediate Release 4th September 2006\n\n\n Gold Oil plc ('Gold') update on the testing of their Peruvian exploration well\n San Alberto-1X.\n\n\n\nIn the offshore San Pedro field wells have drilled some 500 - 600 feet of\nPalaeozoic and the wells are completed 'bare foot' with casing set at the top of\nthe Palaeozoic but none across the Palaeozoic.\n\n\nIn San Alberto-1X Gold drilled 2,300 feet of Palaeozoic and because of severe\nwear on the drilling equipment it was agreed with Perupetro to stop drilling at\n5,113 feet, 135 feet short of the obligation in our Block XXI licence. The\noriginal plan was to drill to 6,500 feet but because of the geology encountered\nin the well Perupetro agreed with our view that at 5,113 feet the well had more\nthan adequately evaluated the Palaeozoic.\n\n\nThe well was logged and some 250 feet of potential hydrocarbon bearing\nPalaeozoic sands were interpreted by our specialists using their experience and\nSchlumberger software. 90% of the hydrocarbons are in a single zone below\n4,570feet with formation water below it.\n\n\nGiven the experience of San Pedro it was decided to test the well 'bare foot'.\nThe drilling rig was moved off the location and a workover hoist moved on\ntogether with tanks and testing equipment. To reduce the bottom-hole pressure,\nand so allow the well to flow, completion fluid was swabbed out of the well and\nthe well flowed highly saline formation water at 960 bwpd. We believe that this\nwater is flowing from the zone below the hydrocarbon zone and is preventing any\nflow of hydrocarbons from above the water zone.\n\n\nWe need to pull the uncemented slotted-liner so that we can shut off the water\nand definitively test the hydrocarbon leg. Discussions with the contractor are\nin hand to mobilise appropriate equipment to the well site.\n\n\nOnce the Palaeozoic test is complete we will test the higher Verdun sands which\nhave some 315 feet of potential hydrocarbon bearing sands in both the equivalent\ngas producing Upper Verdun sands in the nearby Las Casita field and the deeper\nthicker Verdun sands that are not present in Las Casita.\n\n\nThe technical information contained in this announcement has been reviewed and\napproved by Mike Burchell, B.Sc., 66, member of the SPE and with over 44 years\nexperience in the oil and gas ...
