Desire Drills Duster in North Falkland Basin
The 14/15-1 well on the Rachel prospect has reached a total depth of 9,439 feet (2,877 meters) using semisub Ocean Guardian. Initial wireline logging analysis shows that hydrocarbons aren't present, but thick sandstones were encountered in the upper part of the targeted zone. This zone compromises 338 feet (103 meters) of gross sandstone of which 268 feet (81 meters) is net reservoir with an average porosity of 23%. Desire stated that the Rachel prospect has provided new valuable data on the distribution of the reservoir targets within the Eastern Flank play and in particular, the calibration of the 3D seismic data for sandstone prediction. Based on the latest data, potential sandstones have been identified downdip from the existing location, closer to the mature oil source rock, significantly reducing the oil charge risk. The well will now be sidetracked to this location to evaluate the prospectivity. Sidetrack drilling will commence when logging operations are completed. The total depth of the sidetrack well is planned to be 11,214 feet (3,418 meters) with an offset of .7 of a mile (1.2 kilometers) from the total depth of the original vertical well. The sidetrack will be designated 14/15-1Z and should take about 20 days to complete. Desire Petroleum, holding a 92.5% interest, operates the prospect; Rockhopper Exploration holds the remaining 7.5% interest.SubseaIQ provides focused, in-depth coverage of offshore field development activities around the world, with daily updates on hundreds of offshore fields and facilities.
