AWE, the operator of production licenses L1/L2 in the northern Perth basin, Western Australia, said the Waitsia-3 appraisal well was at 3578m measured depth below rotary table (MDRT) and drilling ahead to a planned total depth (TD) at 3706m MDRT.

All primary and secondary targets have been intersected. Elevated gas shows were encountered in multiple zones within the Kingia and High Cliff intervals and their significance will be evaluated by wireline logs.

Waitsia-3 was spudded on 19 May 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.

The well is located approximately 19.8km east-south-east of Dongara, Western Australia, and 10.8km south of Waitsia-1. The approved work program for the Waitsia-3 appraisal well does not include hydraulic fracture stimulation. Waitsia is a 50:50 partnership between AWE and Origin Energy.
