AWE Limited has reported that the Waitsia-4 appraisal well has reached a Total Depth (TD) of 3,744 m after encountering a series of promising gas shows in a number of target zones.

The operator of Production Licences L1/L2 in the northern Perth Basin, AWE said that it and JV partner Origin Energy are now preparing to commence a wireline logging programme of the well after it successfully intersected all primary targets.

AWE said wlevated 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 designed to appraise the gas potential in the eastern extension of the Waitsia Field, rated as one of the most exciting onshore gas discoveries in Australia for the past few decades.

AWE said that if the logging results are positive Waitsia-4, will be completed as a production well and a flow test may be performed.

Waitsia-4, the last appraisal well planned for the Waitsia field in 2017, is located approximately 18.5 km south-east of Dongara, north of Perth and 3.3 km north-northeast of Waitsia-3.
