AWE encounters elevated gas shows at Irwin-1

AWE Limited said that the Irwin-1 exploration well, located in the onshore Perth Basin, Western Australia, had reached a total depth of 4,049m and preparations are now underway to commence a wireline logging program.

The Irwin prospect straddles the EP320 and L1 boundary and the Irwin-1 drilling program is being operated by AWE under an agency agreement with joint venture partner, Origin Energy.

Irwin-1 encountered elevated gas shows in the Dongara/Wagina sandstones primary target, the company said in a statement.

Gas shows were also observed in the secondary objectives – the Carynginia Shale, the Irwin River Coal Measures, and the deeper Kingia and High Cliff Sandstones – but their significance is yet to be determined. These intervals will be further evaluated with a wireline logging program.

AWE may undertake a flow test of the Irwin-1 well to better establish the commercial potential of the reservoir(s). The approved work program for the Irwin-1 exploration well does not include hydraulic fracture stimulation.

The Irwin-1 exploration well was spudded on 25 March 2015 and is located approximately 22.7kms east of Dongara, Western Australia. Irwin-1 is the first well of a three well drilling program planned for the Perth Basin in 2015. It will be followed by the Waitsia-1 and Waitsia-2 appraisal wells on the newly discovered Waitsia Gas Field.
