AWE Limited (AWE), the Operator of Production Licences L1/L2 in the northern Perth Basin, Western Australia, advises that as at 06:00 hours (6.00am) AWST today the Waitsia-4 appraisal well was at 3,486 m Measured Depth below Rotary Table (MDRT) and drilling ahead in a 8 1/2 inch (216 mm) hole to total depth, following the successful installation of 9 5/8 inch (244 mm) intermediate casing at 3,054 m MDRT.

The first of the primary targets, the Kingia formation, has been successfully intersected and the well is drilling ahead to the second primary target, the High Cliff Sandstone. Good gas shows were observed in the Kingia and wireline logs will be acquired to confirm reservoir quality.

Waitsia-4 was spudded on 10 July 2017 and is forecast to take approximately five weeks in total to complete. The well will be directionally drilled to a planned maximum total depth of 3,834 m MDRT (3,668m Total Vertical Depth Sub Sea-level). The well is designed to appraise the gas potential in the eastern extension of the Waitsia Field, with primary targets being conventional reservoirs in the Kingia and High Cliff Sandstones.

The well will be logged and, if the results are positive, the well will be completed as a production well and a flow test may be performed. Waitsia-4 is the last appraisal well planned for the Waitsia field in 2017. The Waitsia-4 appraisal well is located approximately 18.5 km south-east of Dongara, Western Australia, and 3.3 km north-northeast of Waitsia-3. The approved work program for the Waitsia-4 appraisal well does not include hydraulic fracture stimulation.

The Joint Venture partners in L1/L2 are: AWE Limited (via subsidiaries) (Operator) 50.0%; and Origin Energy Resources Limited 50.0%.
