AWE Continues Drilling at Waitsia-1 Appraisal Well in Western Australia

AWE Limited, the Operator of Permits L1/L2 in the Perth Basin, Western Australia, reported Friday that as at 06:00 hours (6.00am) AWST today the Waitsia-1 appraisal well in the Perth Basin, Western Australia was at a Measured Depth below Rotary Table (MDRT) of 9,616 feet (2,931 meters) and drilling ahead in a 8.5 inch hole to the planned total depth of 13,287 feet (4,050 meters), following the successful installation of 9.625 inch intermediate casing at 7,874 feet (2,400 meters).

The Dongara Sandstone, a secondary target, was intersected at 8,999 feet (2,743 meters) MDRT as prognosed with elevated gas shows recorded.

The Waitsia-1 well was spud May 14 and is forecast to take approximately six weeks in total to complete. The well will be drilled vertically to its planned total depth of 13,287 feet (4,050 meters) MDRT and is designed to further test the gas potential of the Waitsia Field, comprising primary targets in the deep conventional formations in the Kingia and High Cliff Sandstones.

The well will be logged and core samples will be collected and sent for analysis. Secondary targets in the shallower Dongara and Wagina tight sandstone formations, the Carynginia Shale and Irwin River Coal Measures will be intersected prior to reaching the primary targets.

If the results are positive, AWE may undertake a flow test of the Waitsia-1 well and the well may be completed as a production well for a potential future field development. The approved work program for the Waitsia-1 appraisal well does not include hydraulic fracture stimulation.

The Waitsia-1 appraisal well is located on agricultural land approximately 10.6 miles (17 kilometers) east of Dongara, Western Australia, and 6.2 miles (10 kilometers) from the operating Dongara gas plant. The well is the second of a three well drilling program planned for the Perth Basin in 2015. It will be followed by the Waitsia-2 appraisal well in the second half of the 2015 calendar year.

The Joint Venture partners in L1/L2 are:
