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 southeast of Dongara, Western Australia, and 3.3 km north-northeast of Waitsia-3. The approved work programme for the appraisal well does not include hydraulic fracture stimulation.
