Spudded on 25 March 2015, the Irwin-1 exploration well will be drilled vertically to a planned total depth of 4,064m and is expected to take approximately seven weeks to complete.
The well aims 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.
The company will carry out a flow test of the Irwin-1 well to establish the reservoirs’ commercial potential, if the results are positive.
Following completion of Irwin-1 well, AWE will drill Waitsia-1 and Waitsia-2 appraisal wells on the newly discovered Waitsia gas field.
