Origin Energy Makes Discovery at Jingemia 1

Origin Energy reports that preliminary indications from the Drill Stem Test 2 in the Dongara Sandstone over the interval 2407.3 meters to 2419 meters has recovered 26.5 barrels of 37 degree API oil during a 3 hour flow period. Some associated gas and condensate was also recovered, no water is reported.

The Drill Stem Test tool is currently being retrieved. Consequently, no charts have yet been recovered or analyzed to establish the validity of the test, confirm the recovery or establish whether there was any depletion of the reservoir during the test.

Origin Energy's General Manager Exploration Dr Rob Willink said "Although encouraged by the oil recovery that establishes this well as a new field oil discovery in the Perth Basin, it is too early to speculate on the commercial significance of this accumulation as the oil column height is not as yet known and the Drill Stem Test charts have not been inspected".

Following retrieval of the Drill Stem Test tool, drilling will continue to determine the extent of the hydrocarbon column and the thickness of the reservoir. Once this has occurred, a decision will be made whether to run wireline logs and case off the Dongara Sandstone prior to drilling ahead to the secondary High Cliff Sandstone target in 6-inch hole.
