AWE Limited (AWE), the operator of production licences L1/L2 in the northern Perth Basin, Western Australia, has announced that that the Waitsia-4 appraisal well commenced drilling operations on 9 July.

On 10 July, the well was at 212 m measured depth below rotary table (MDRT) and drilling ahead in the 17.5 in. (445 mm) hole section.

The Waitsia-4 well will be directionally drilled to a planned maximum total depth of 3834 m MDRT (3668 m total vertical depth sub sea-level) and is forecast to take approximately five weeks in total to complete. The well is designed to appraise the gas potential in the eastern extension of the Waitsia field, with primary targets being conventional reservoirs in the Kingia and High Cliff Sandstones.

Waitsia-4 is the last appraisal well planned for the Waitsia field in 2017.

David Biggs, CEO and Managing Director of AWE, said: “Waitsia-4 will be the last appraisal well drilled by the joint venture before we reach a final investment decision on Waitsia Stage 2 development.”

“The data from Waitsia-3 and Waitsia-4 will provide us with a sound basis for upgrading our estimated 2P Reserves for the Waitsia field before the end of 2017 calendar year,” Biggs added.
