Origin Energy Strikes with Jingemia 10 Well

Origin Energy Limited reports that the Jingemia 10 well, located in the onshore Perth Basin Production License L14, was drilled to a total measured depth of 2,587 meters. Wireline logs have been run and indicate that the target Dongara Sandstone has been intersected at 2,458.5 meters measured depth, approximately 40 meters above the presumed field oil water contact. The Dongara Sandstone is 34.5 meters thick at the Jingemia 10 location and is of good quality with oil shows present throughout the interval. Wireline log interpretation indicates oil saturations throughout the Dongara Sandstone similar to the Jingemia 4 well.

Completion of the well and connection to the Jingemia production facility is expected to commence following the running of casing, once the drilling rig has moved off location.

The Jingemia 10 surface location is 760 meters north of the Jingemia oil production facility.

Participants in L14 and Jingemia 10 are: Origin Energy Developments Pty Ltd (Operator) 49.189%; ARC Energy Limited 33.141%; Voyager (PB) Limited 11.000%; Victoria Petroleum Offshore Pty Ltd 5.000%; Norwest Energy NL 1.278% Roc Oil Pty Ltd 0.250%; and J. K. Geary 0.142%.
