AWE confirms extension of Waitsia gas field in Australia
Energy company AWE has confirmed the southern extension of the Waitsia gas field in the northern Perth Basin, Western Australia.
The confirmation follows a preliminary analysis of wireline log and pressure data from the appraisal of Waitsia-3 well, which is located about 19.8km east-south-east of Dongara and 10.8km south of Waitsia-1.
Waitsia-3 encountered strong gas shows across a 150m gross interval, including the Kingia and High Cliff Sandstone reservoir targets.
The Waitsia field is an onshore conventional gas discovery with the potential to supply the domestic market with 100 TJ/d for ten years from conventional reservoirs.
AWE Managing Director and CEO David Biggs said: “The substantial thickness of the Kingia reservoir, combined with exceptional porosity, net pay and low levels of total inerts, confirms excellent reservoir quality in the southern extent of the Waitsia field.
“The observation of gas below the previously interpreted GWC may also have positive implications for the rest of the field and provide new appraisal and exploration opportunities within the permits.”
The company is expected to continue its analysis of the Waitsia-3 data, despite its plans to spud the Waitsia-4 appraisal well in the first half of this month.
AWE will be able to review the estimated reserves and resources for the entire Waitsia field using the data gathered from both wells.
The company expects a further upgrade to reserves within the second half of this year based on the Waitsia-4 results.
The Waitsia-3 well has currently been suspended for future testing and production.
AWE previously planned a two-well appraisal drilling programme for the Waitsia field this year. The first well, Waitsia-3, was spudded in May.
