AWE Limited, the Operator of Permits L1/L2 in the Perth Basin, Western Australia, advises that at 06:00 hours (6.00am) AWST today the Waitsia-1 appraisal well was at a Measured Depth below Rotary Table (MDRT) of 3,367m and was completing coring operations before drilling ahead in a 8 ½ inch hole to the planned total depth of 4,050m.

Two sections of core were cut in the primary target, the Kingia and High Cliff Sandstones. Core #1 was cut from 3,318m to 3,345.5m MDRT and Core #2 was cut from 3,345.5m to 3,367m MDRT. Both cores will be sent for analysis. Wireline logs will be run over a number of intervals, including the Dongara and Kingia, after the well has reached total depth.

The Waitsia-1 well was spudded on 14 May 2015 and is forecast to take approximately six weeks in total to complete. The well will be drilled vertically to its planned total depth of 4,050m 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.

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 forthe Waitsia-1 appraisal well does not include hydraulic fracture stimulation.

The Waitsia-1 appraisal well is located on agricultural land approximately 17km east of Dongara, Western Australia, and 10km 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.
