HOUSTON, Oct. 17 -- An appraisal well on the Hook Head structure in the North Celtic Sea basin off Ireland found 75 ft of net pay in 484 ft of gross hydrocarbons in the main target zone and a combined 20 ft of net pay in three shallower exploration targets.

Providence Resources PLC, Dublin, operator of License 2/07, drilled the well 60 km offshore in 240 ft of water on the crest of a structure penetrated by earlier wells in 1971 and 1975. TD is 4,880 ft true vertical depth.

The four Cretaceous reservoirs had porosities as high as 27% with 30° gravity oil and associated gas.

Providence and partners recovered good quality oil and were hampered in testing by a poor casing cement job. They demobilized the rig due to rig contract time limits and were discussing further appraisal/development drilling early in the 2008 drilling season. The site is 60 km east of Kinsale Head gas field.

Working interests are Providence 43.5294%, Challenger Minerals (Celtic Sea) Ltd. 16.3235%, Dyas BV 16.3235%, Forest Gate Resources Inc. 7.5%, Atlantic Petroleum (Ireland) Ltd. 10.8824%, and Sosina Exploration Ltd. 5.4412%.
