Australian energy company AWE said the Waitsia-4 appraisal well in the onshore Perth basin of Western Australia, was at 212m measured depth below rotary table (MDRT) and drilling ahead in the 445mm hole section.

Waitsia-4 will be directionally drilled to a planned maximum total depth of 3834 m 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. It is the last appraisal well planned for the Waitsia field in 2017.

“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,” said CEO David Biggs.

“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,” he added.

AWE anticipates booking additional Waitsia reserves in the second half of 2017, following the successful appraisal of the Waitsia-3 well, the first of a two-well drilling program.

Preliminary analysis of wireline log and pressure data from the well has confirmed the southern extension of the Waitsia gas field by encountering strong gas shows.

Located in the production license L1/L2 Waitsia is a 50:50 partnership between AWE and Origin Energy.
