What we do
Mitsui E&P Australia’s operations in the northern Perth Basin are located near the town of Dongara approximately 360km north of Perth and 65km south of Geraldton in Western Australia.
We are actively exploring, appraising, developing and producing oil and gas in a number of locations in the Mid West of Western Australia. Our projects cover the full life-cycle range from exploration to production and decommissioning. Health, safety and environment protection are our highest priorities wherever we operate.
The locations of our current projects are highlighted in the following map. More details on projects are provided in the schedule of activities planned for FY 20/21.

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.
