THE largest onshore gas field found in WA for decades has been deemed commercially viable by oil and gas explorer AWE.

AWE discovered gas when drilling at the Waitsia field in the Perth Basin, east of the Mid West town of Dongara last year.

AWE managing director Bruce Clement said the excellent results from the Waitsia-1 appraisal well highlighted the significant conventional gas production potential of the north Perth Basin.

“The further success in Waitsia-1, following discoveries in the Senecio-3 and Irwin-1 wells, has reconfirmed the potential of the North Perth Basin to deliver substantial volumes of commercial gas into the Western Australian domestic gas market,” Mr Clement said.

“The Perth Basin is well served by infrastructure and pipelines and, subject to joint venture and regulatory approvals, AWE is targeting early production from Senecio-3 and Waitsia-1 wells by mid- 2016. “

Following the announcement AWE spudded the Waitsia-2 well about 5.6km south-southwest of Waitsia-1, which will be drilled to a maximum depth of 3803m and will take about seven weeks to complete.

The well was designed to evaluate the southern extent of the Waitsia gas field and appraise the upside potential found in Waitsia-1.

Waitsia-1 will be completed and suspended after further evaluation and testing as a future production well.

AWE has begun gas marketing and has held meetings with potential customers for early stage gas production.
