Schedule of Activities
Our projects in the Perth Basin cover the various stages of project life-cycle. Following are key activities planned for FY 2019/20:
L1/L2 Permit Areas (Shire of Irwin Region)
| Activity | Description | Indicative Timing |
| Exploration/Appraisal | Most recent appraisal activities focused on the Waitsia gas field. Flow tests conducted in 2017 of Waitsia-02, Waitsia-03 and Waitsia-04 appraisal wells showed outstanding flow test results. This appraisal information has been used to supplement data gained from the Waitsia Stage 1 extended production test. | No exploration or appraisal drilling is planned for FY 19/20 |
| Production – Waitsia Stage 1 | The Stage 1 Expansion is being commissioned prior to resuming production. This involved connecting a third well and increasing production from 10 TJ/day to 20 TJ/day and also constructing a gas export pipeline to the nearby Dampier to Bunbury Natural Gas Pipeline. | Production Q3 2020 |
| Full Field Development – Stage 2 (proposed) |
Stage 2 will involve connecting up to six wells to a newly constructed 250 TJ/day gas production facility planned to be located near the existing Xyris Production Facility. Waitsia Stage 2 is in the planning and design phase. Regulatory approvals are underway. |
To be confirmed |
| Care and Maintenance |
The Hovea Production Facility is not producing and has been in Care and Maintenance since 2010. The Dongara Production Facility is being prepared for partial Care and Maintenance as the Dongara gas field ceased production in 2017. |
Ongoing |
| Perth Basin Decommissioning and Rehabilitation Project | Well site decommissioning activities are being undertaken as part of a Mid West permit areas campaign to decommission then rehabilitate sites which are no longer in use. | Two wells during FY 2019/20 |
L4/L5 Permit Areas (Shire of Carnamah Region)
| Activity | Description | Indicative Timing |
| Exploration/Appraisal |
Two airborne exploration surveys are proposed to be undertaken over three southern Perth Basin permits – L4/L5 and EP455. Further assessment of the Woodada gas field, that ceased producing in 2010, is also occurring through desktop studies. This review was prompted by the Waitsia gas field discovery in 2014. Many other companies are also reassessing data for their permits in the northern Perth Basin since this exciting discovery was made. |
Airborne exploration surveys planned mid-September to mid-October 2020 No exploration or appraisal drilling is planned for FY 19/20 |
| Care and Maintenance | The Woodada Production Facility is not producing and has been in Care and Maintenance since 2010. | Ongoing |
| Perth Basin Decommissioning and Rehabilitation Project | Well site decommissioning activities are being undertaken as part of a Mid West permit areas campaign to decommission then rehabilitate sites which are no longer in use. | Two wells during FY 2019/20 |
Note: All our activities involve conventional gas fields and all ‘Indicative Timing’ is subject to corporate, JV and regulatory approvals.
L1/L2 Permit Areas (Shire of Irwin Region)

Planning
Before anything can happen we need to plan carefully. Read more about the planning process.
Exploration/Appraisal
We look for gas, and when we find it we figure out if it’s worth pursuing further. Find out more about our exploration and appraisal process.
Development
Once we’ve confirmed a well is commercially viable we get ready to put it into production. Read more about the development process.
Production
During the production phase we produce gas from the well and sell it. Find out more about the production process.
Decommissioning and Rehabilitation
When the exploration or production activity has finished it’s time to clean up. Read more about how we decommission and rehabilitate a well and its surrounding area.
