Who we are

Mitsui E&P Australia Pty Ltd and AWE Limited are both wholly owned subsidiaries of Mitsui & Co., Ltd. (Japan), and are now sister companies.  We are working under the single brand of Mitsui E&P Australia (MEPAU) to reflect the recently combined businesses.

We operate as regional headquarters for Mitsui’s oil and gas exploration and production business in Australia, New Zealand, Papua New Guinea and East Timor. We have approximately 60 people working at our head office in Perth and at site.

Since MEPAU was founded in 2004, the company has grown to become one of Australia’s largest oil producers. MEPAU has six producing oil and gas assets in Australia and is Operator of the four facilities in the Mid West of Western Australia. The company also has interests in 20 projects that are in various exploration and development stages.

We are committed to delivering safe, reliable and affordable energy. With our acquisition of AWE in May 2018 we are now part of the rich history of oil and gas production of the Mid West region.

Gas is produced from our wells and processed at our operated facilities in the Mid West, then added into the Parmelia Pipeline for transport to customers.

During normal operations we employ approximately 11 full time employees in the Mid West. This number increases substantially during periods of exploration, decommissioning and development activity.

We pride ourselves on our policy of employing local people and using local businesses wherever practicable. In the Mid West, our work force lives locally, we don’t have fly in/fly out (FIFO) workers.

We operate openly, transparently and in good faith. We are committed to communicating clearly with the Mid West communities in which we operate. Members of the community are welcome to attend independently facilitated round table events to ensure that their questions are answered and any concerns are heard.

The company has a strong track record in safety, environmental management, exploration, development and production. We have built a solid reputation through our successful projects.

MEPAU is currently involved in the following Australian projects:

  • Waitsia Gas Project – onshore production and development assets, northern Perth Basin, WA (Operator)
  • Vincent and Enfield oilfields and Greater Enfield Oil Development Project– offshore North West Cape, WA
  • Casino Gas Project – offshore Otway Basin, Victoria
  • BassGas project – offshore Bass Basin, Tasmania
  • Kipper Gas project– offshore Gippsland Basin, Victoria
  • Meridian coal seam gas project – onshore Bowen Basin, Queensland

We are seeking new business opportunities in Australasia, and aim to increase reserves replacement by establishing new exploration projects as well as acquiring additional oil and gas assets.
