The Waitsia-4 appraisal well reached total depth (TD) of 3744 m measured depth below rotary table (MDRT) at 15:30 hours (3.30 pm) AWST on 10 August 2017 and preparations are now being made to commence a wireline logging programme.
TD was achieved in the Holmwood Shale after successfully intersecting all primary targets. Elevated gas shows were encountered in multiple zones in the Kingia and High Cliff intervals and their significance will be evaluated during the wireline logging phase. Good gas shows were also encountered in the Irwin River Coal Measures, a secondary target.
Waitsia-4 was spudded on 10 July 2017 and is designed to appraise the gas potential in the eastern extension of the Waitsia Field. The well will be logged and, if the results are positive, it 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.
