Operator AWE said the Waitsia-3 appraisal well in the northern Perth basin in Western Australia, is at 2782m measured depth below rotary table (MDRT) and preparing to drill ahead.

The well will be drilled in a 216mm hole to the primary target, following the installation of a 244mm intermediate casing at 2779m MDRT.

Waitsia-3 was spudded on 19 May and is forecast to take approximately seven weeks in total to complete. The well will be drilled vertically to a planned total depth of 3706m MDRT and is designed to appraise the gas potential in the southern extension of the Waitsia field.

It will target the conventional reservoirs in the Kingia and High Cliff Sandstones, and the sandstone reservoirs of the Irwin River Coal Measures.

The well will be logged and core samples will be collected and sent for analysis. 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 19.8km 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. The Waitsia gas project is a 50:50 joint venture between AWE and Origin Energy.
