AWE said the Waitsia-4 appraisal well in the northern Perth basin, Western Australia, was at the planned 311mm section depth of 3054m measured depth below rotary table (MDRT) and preparing to run 244mm casing.

Waitsia-4 was spudded on 10 July 2017 and is forecast to take approximately five weeks to complete. The well will be directionally drilled to a planned maximum total depth of 3834 m MDRT.

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 18.5km southeast of Dongara, Western Australia, and 3.3km north-northeast of Waitsia-3. The approved work program for the Waitsia-4 appraisal well does not include hydraulic fracture stimulation. The project is a 50:50 joint venture between operator AWE, and Origin Energy.
