Drover-01 exploration well
- The Drover-01 exploration well site is located on agricultural land in the Shire of Coorow, adjacent to the Lesueur National Park and near the Mount Peron Water Reserve.
- The well was successfully drilled in mid-2014 without any significant health, safety or environmental incidents.
- Gas readings were observed while drilling and core samples and logs were taken over the target zones to evaluate their shale and tight gas potential.
- Initial results indicated that the Kockatea Shale at this location has good source potential for gas liquids and three intervals have been identified that could constitute targets for future operations or appraisal.
- A diagnostic test, Diagnostic Fracture Injection Test (DFIT), over one of the target zones was conducted in April 2015. This test, which used a mix of water and saline water, assessed reservoir pressure, permeability, natural fracturing and potential for hydraulic fracture stimulation.
- The results of the DFIT showed that the majority of the target formation at Drover-01 was unlikely to have sufficient natural fracturing or propensity for hydraulic fracturing to achieve a commercial flow rate of gas and the well has been decommissioned and rehabilitated.
Based on the exploration results at Drover-01, Mitsui E&P Australia’s predecessor AWE concluded that sufficient technical information has been gathered to complete assessment of the shale gas potential at this location and that no further work was required at this location. Rehabilitation at Drover-01 has been completed and the site returned to the landowner.
Mitsui E&P Australia (MEPAU) is planning further exploration work in the permit area.
The technical information gathered at Drover-01 is helping prepare a new forward work program for the renewed permit area being sought.
The Denison 3D Seismic Survey was the most complicated survey ever done in Australia at the time. Find out more about what was involved in the Denison 3D Seismic Survey.
The Irwin-01 exploration well was completed in May 2015. Find out more about the current status of Irwin-01.
Woodada Deep-01 was drilled in April 2012. It was a deepening of the Woodada-04 well. Find out more about the current status of Woodada Deep-01.
