Australian Projects
Onshore Perth Basin (Waitsia, Beharra Springs)
MEPAU's onshore Perth Basin assets, located near the town of Dongara, are approximately 360 kilometres north of Perth in Western Australia. Produced gas from the Waitsia Gas Field is processed by the Xyris Production Facility and the Waitsia Gas Plant, operated by MEPAU (50%) in joint venture with Beach Energy (50%). MEPAU also has a 50% interest in the Beharra Springs Gas Plant (operated by Beach Energy), which processes gas produced from the Beharra Springs Deep gas field.

Vincent and Greater Enfield Projects
The Vincent and Greater Enfield crude oil projects are located approximately 50 kilometres northwest of Exmouth, off the coast of Western Australia. The projects are owned by joint venturers MEPAU (40%) and Woodside (60%), with Woodside serving as the operator of all fields. The Greater Enfield Development (GED) project developed reservoirs located within the same area as the Enfield and Vincent oil fields. These fields were developed using floating production storage, and offloading (FPSO) vessels to produce, store, and offload oil.
The Enfield oil field began production in July 2006 and ceased production in November 2018. The Nganhurra FPSO used for Enfield has now been removed from the field. All wells have been plugged and abandoned, and the subsea infrastructure has been recovered and recycled onshore.
The Vincent Project started production from the Ngujima-Yin FPSO in August 2008. The joint venture partners made a final investment decision on the GED Project in June 2016, based on tying back twelve additional production and injection wells to the Ngujima-Yin FPSO
Kipper Project
The Kipper gas and liquids project, located in the Gippsland Basin around 45 kilometres off the coast of Victoria, is owned by a joint venture between MEPAU (35%), Esso Australia (a subsidiary of ExxonMobil) (32.5%), and Woodside (32.5%).
The field is operated by Woodside, with raw gas transported to the onshore Longford Gas Conditioning Plant, owned by Esso Australia and Woodside, where it is processed before gas and associated products are supplied to customers.
Greater Meridian Project
MEPAU is a joint venture partner (49%) with WestSide (51%), who is the operator of the Greater Meridian Permits.
The project is strategically positioned with direct exposure to both domestic and international gas markets, underpinned by physical connectivity to the Queensland Gas Pipeline and the Gladstone LNG (GLNG) network. A significant proportion of production is contracted under long-term gas sales agreements to the Santos-operated GLNG project, providing indirect exposure to global LNG pricing dynamics, including oil-linked (JCC) pricing mechanisms.
In addition, the ability to supply gas into the East Coast domestic market provides flexibility to optimise sales between export-linked LNG pricing and domestic gas demand. This dual market exposure positions the Greater Meridian asset as an integrated upstream gas development with diversified revenue streams across both LNG export and domestic markets.
