AWE Limited reported that as at 06:00 hours (6.00am) AWST today the Irwin-1 exploration well, located in the onshore Perth Basin, Western Australia, was at a measured depth of 2,996m and drilling ahead in 8 1/2 inch hole to the planned total depth of 4,064m, following the successful installation of 9 5/8 inch intermediate casing at 2,768m.
The Irwin prospect straddles the EP320 (AWE 33%) and L1 (AWE 50%, Operator) boundary and the Irwin-1 drilling program is being operated by AWE under an agency agreement with joint venture partner, Origin Energy Limited (ASX: ORG).
The Irwin-1 exploration well was spudded on 25 March 2015. The well is being drilled vertically to a planned total depth of 4,064m and is forecast to take a total of approximately seven weeks to complete.
Irwin-1 is designed to test the gas potential to the east of the Senecio and Waitsia gas fields and is targeting the Dongara and Wagina tight sandstone formations, the Carynginia Shale and Irwin River Coal Measures, as well as deeper conventional targets in the Kingia and High Cliff Sandstones.
If the results are positive, 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 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 Fie
