Irwin-1 exploration well

The Irwin-1 exploration well is located on agricultural land 23km east of Dongara. The well straddles the EP320 exploration permit and L1 permit. The Irwin-1 well was completed in May 2015 and reached a target depth of 4,049 metres in four weeks.

The well is designed to target the same potential reservoirs intersected by the Senecio-3 well. The primary targets were the Dongara/Wagina sandstones, which were intersected during drilling operations. During drilling operations, AWE announced elevated gas shows were observed.

The drilling rig used for Irwin-1 was demobilised from site and used to drill the Waitsia-1 appraisal well.

Future plans

  • No flow testing is planned for the Irwin-1 well.
  • The approved work program for the well does not include hydraulic fracture stimulation.
