PORT STANLEY, Falkland Islands -- The Desire Petroleum will P&A its latest exploration well in the offshore North Falkland basin after encountering only gas shows at a depth of 1,434 m (4,704 ft). The well reached a TD of 1,697 m (5,567 ft) in pre-rift sediments.
Preliminary drilling and wireline logging data from the 25/5-1 well suggest there are no significant hydrocarbons in the Dawn prospect. Desire adds that the lithology in the section from 1,313-1,697 m (4,308-5,567 ft) is chiefly claystone and good quality sandstone, with 71 m (233 ft) of net reservoir based on initial log analysis.
The Dawn well was testing a significant fault block at the southern margin of the main basin, 28 km (17.4 mi) from previous well control, the main reservoir targets being in the syn-rift and pre-rift which are stratigraphically older than the reservoirs in the East Flank play.
Desire will assess the implication of the well results for remaining prospectivity in this part of the basin once it has completed integration of the new data and all post-well studies.
Following wireline logging and abandonment operations, the semisubOcean Guardian will drill one or two wells for Rockhopper Exploration, subject to regulatory approval, before drilling another well for Desire at a still to be determined location.
