Desire draws blank at Dawn

Drilling at Desire Petroleum's 25/5-1 well on the Dawn/Jacinta prospect in the North Falkland Basin has reached target depth but failed to find any oil."Based on preliminary drilling and wireline logging data there are no significant hydrocarbons in the Dawn prospect and the well will be plugged and abandoned with gas shows around 1,434 metres," said the company after drilling down 1,697 metres."The lithology in the section from 1,313 to 1,697 metres is predominantly claystone and good quality sandstone with 71 metres of net reservoir based on initial log analysis."The rig will now move to Rockhopper Exploration which will drill "one or two wells", subject to regulatory approval, before returning to Desire to drill a well at a location still to be finalised and subject to regulatory approval."The Dawn well was testing a significant fault block at the southern margin of the main basin, some 28 km from previous well control, with primary reservoir targets in the syn-rift and pre-rift," explains Desire. "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 post-well studies are completed."
