The first well of a three well drilling program planned for the Perth Basin in 2015, the Irwin-1 exploration well is located approximately 22.7km east of Dongara, Western Australia.

Upon completion of Irwin-1 well, AWE will drill the Waitsia-1 and Waitsia-2 appraisal wells on the newly discovered Waitsia gas field.
