Project Profile
Location: 22.7km east of Dongara, Western Australia
2C Contingent Resources: 424 mcm of gas
Depth: 4,064m
The Irwin prospect is located in the onshore Perth Basin. The Irwin-1 exploration well is located approximately 22.7km 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. 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.
