AWE Limited, the Operator of Production Licences L1/L2 in the northern Perth Basin, Western Australia, advises that the Waitsia-4 appraisal well is at 1512 m Measured Depth below Rotary Table (MDRT) and drilling ahead in a 12 ¼ in. (311 mm) hole to the next planned section depth of 3065 m MDRT, following the successful installation of 13 3/8 in. (340 mm) surface casing at 1166 m MDRT.

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 3834 m MDRT (3668 m 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%
  • Origin Energy Resources Limited – 50.0%
