How we plan and develop our projects

Mitsui E&P Australia’s philosophy is to engage early and often. We commit ourselves to communicating extensively with local stakeholders because we want to be open and transparent about what we’re doing. We also have confidence in the safety of our operations.

Our company considers the life-cycle of a project from the initial planning phase through to development and decommissioning to ensure environmental, health and safety, community and business factors are addressed and that each of our projects is undertaken safely and responsibly.

Mitsui E&P Australia (MEPAU) understands the high value placed on the environment of the Mid West by landowners, community members and other stakeholders. We are committed to protecting these values, and undertake rigorous risk assessments as part of project planning and in preparation for seeking project approvals.

Our company prepares approvals documentation in accordance with legislated approvals processes administered by the Department of Mines, Industry Regulation and Safety, the Environmental Protection Authority and other government agencies.

Before MEPAU begins a proposal to develop a project we complete the following:

  1. A comprehensive risk assessment
  2. Engage with our stakeholders
  3. Maintain communication and transparency

Project planning

A comprehensive risk assessment is undertaken to identify all of the potential impacts a project may have on an area, then we proceed to understand how these can be effectively managed by implementing protection measures. If science tells us that a risk can’t be managed then the outcome is simple, that particular project is no longer an option.

Engaging with our stakeholders

Our stakeholders may be members of the community such as landowners, traditional owners on whose land we operate or shire residents. They also include relevant regulators and decision makers.

Maintain communication and transparency

Beyond initial discussions, we continue to maintain open communication with stakeholders about our activities as they develop.

To increase the level of engagement between MEPAU and residents of the Shire of Irwin, we have sponsored an independently facilitated Community Roundtable with in-kind support from the Shire.  Participants in the roundtable workshops have included local residents, local business owners, local landowners, regulators, shire councillors and staff as well as MEPAU personnel.

This roundtable group has operated independently of our company, although MEPAU has provided information specifically requested, and like a number of other stakeholders including regulators and subject matter experts, has participated in the group by invitation.

What we do at Mitsui E&P Australia

What we do

We are actively exploring, appraising, developing and producing oil and gas in a number of locations in the northern Perth Basin. Read more about what we do


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.


Once we’ve confirmed a well is commercially viable we get ready to put it into production. Read more about the development process.


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.

The Northern Perth Basin

The northern Perth Basin is a prolific oil and gas producing area covering a large portion of the Mid West region of Western Australia. The town of Dongara, located approximately 360km north of Perth, is the regional economic hub for a number of industries, including oil and gas.
