AWE Limited, the operator of Production Licences L1/L2 in the northern Perth Basin, Western Australia, advises that the Waitsia-3 appraisal well reached Total Depth (TD) of 3,612 m Measured Depth below Rotary Table (MDRT) and preparations are now being made to commence a wireline logging programme.
TD was achieved as planned 25 m into the igneous basement which was intersected at 3587 m MDRT, 105 m high to prognosis.
All primary and secondary targets were successfully intersected. Elevated gas shows were encountered in multiple zones within the Kingia and High Cliff intervals and their significance will be evaluated during the wireline logging phase.
Waitsia-3 was spudded on 19 May 2017 and is forecast to take approximately seven weeks in total to complete. The well is designed to appraise the gas potential in the southern extension of the Waitsia Field, with primary targets being conventional reservoirs in the Kingia and High Cliff Sandstones and the secondary target being the sandstone reservoirs of the Irwin River Coal Measures.
Waitsia-3 is the first of a two well appraisal drilling program planned for the Waitsia field in 2017. If the results are positive, the well will be completed as a production well and a flow test may be performed.
Waitsia-3 is located approximately 19.8 km east-south-east of Dongara, Western Australia, and 10.8 km south of Waitsia-1. The approved work programme for the Waitsia-3 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%.
