Falkland Islands: Dawn gas show well plugged

By OGJ editors
HOUSTON, Jan. 4
-- Desire Petroleum PLC plugged the 25/5-1 exploratory well on the Dawn/Jacinta prospect after it encountered gas shows in the North Falkland basin in the South Atlantic.

The well went to a total depth of 1,697 m in prerift sediments. The well found gas shows around 1,434 m. Lithology at 1,313-1,697 m is mainly claystone and good quality sandstone with 71 m of net reservoir based on initial log analysis.

The Dawn well tested a large fault block at the main basin southern margin 28 km from previous well control and had primary reservoir targets in the synrift and prerift (see map, OGJ, Nov. 1, 2010, p. 61). These targets are stratigraphically older than the reservoirs in the East Flank play.

The implication of the well results for remaining prospectivity in this part of the basin will be assessed once the new data has been integrated and all postwell studies are completed, Desire said.

The rig will transfer to Rockhopper Exploration PLC to drill one or two wells, subject to regulatory approval, before returning to Desire to drill a well at a location still to be finalized and subject to regulatory approval.
