AWE Limited has spudded the Irwin-1 exploration well in Western Australia’s Perth Basin.
The company is currently operating the Irwin-1 drilling program under an joint agency agreement with joint venture partner, Origin Energy Limited.
The well is looking 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.
The well will be drilled vertically to a planned total depth of 4,064metres and is forecast to take around seven weeks to complete.
AWE Limited said if the results are positive, it may undertake a flow test of the Irwin-1 well to better establish the commercial potential of the reservoir.
The approved work programme for the exploration well does not include hydraulic fracture stimulation.
The well is the first of a three well drilling program planned for the Perth Basin in 2015.
It will be followed up by the Waitsia-1 and Waitsia-2 appraisal wells on the newly discovered Waitsia Gas field.
