PERTH BASIN OPERATIONS
Beach’s Perth Basin operations consist of the Waitsia project (non-operated) and Beharra Springs (operated) projects.
The Beharra Springs Gas Processing Facility is a 25 TJ per day plant, processing gas from nearby wells and transporting it through the Parmelia pipeline to domestic customers in Western Australia.
Beach is working with its joint venture partner Mitsui E&P Australia (operator) to progress the Waitsia Stage Two Gas Project, with first gas expected in 2023.
WAITSIA GAS PROJECT STAGE TWO
Beach Energy and its joint venture partner, Mitsui E&P Australia (operator) are excited to progress the Waitsia Stage Two project in the Perth Basin.
The Waitsia gas field is ranked one of the largest gas fields ever discovered onshore in Australia.
Waitsia Stage 2 will involve further development of the gas field, with more wells and a new production facility capable of producing 250 TJ/day.
Significant economic benefits flow to the Mid West region from the financial investments that are being made during both construction and operating phases.
Waitsia Stage 2 is in execution stage and a joint venture unconditional Financial Investment Decision (FID) was reached February 2021.

AUSTRALIA’S NEWEST LNG PLAYER
In addition to domestic supply, Beach will export its share of gas from the Waitsia Stage Two project via the North West Shelf, making Beach Australia’s newest LNG player.
First equity LNG sales from Waitsia Stage 2 are expected to commence in 2023.
In alignment with the Government of Western Australia policy, approximately 60% of the project’s greenhouse gas (GHG) emissions are planned to be reduced or offset during the project’s life.
SEISMIC SURVEYS IN MID-WEST WA
Beach Energy is planning to undertake seismic surveys in the north Perth Basin, around 40 kilometres south east of Dongara, over the next few years.
The aim of these surveys is to identify natural gas reserves within our existing exploration permits and production licenses. The data collected will be used to inform future exploration activities in the area which may lead to natural gas production activities over the next 20 years.

- Safety and environmental sustainability are priorities for Beach, and only proven technologies are used in our operations
- Beach does not undertake any fracture stimulation (fracking) activities in the Perth Basin
- Exploration in the Perth Basin commenced in the late 1940s
- More than 200 wells have been drilled onshore in the Perth Basin since that time
Geology OF THE PERTH BASIN
The Perth basin is a Silurian to Recent basin with a complex structural history and at least seven major basin phases. The basin features several deep depocentres with a maximum sediment thickness of 15000m. Perth Basin strata feature a wide range of depositional environments including alluvial, fluvial, glacially-influenced, lacustrine, deltaic and marine.
To the east the basin is bounded by the Darling Fault which is a major crustal-scale feature separating Archean-Proterozoic basement of the Yilgarn Craton from the Perth Basin sedimentary sequences. In the onshore regions most commercial fields produce from Permian-aged sandstone reservoirs although time-equivalent carbonate facies also form reservoirs in places.
Oil is generally thought to be sourced by marine shales of the Early Triassic Kockatea Formation whilst gas is sourced from multiple carbonaceous shales and coaly sequences of Permian, Triassic and Jurassic age. Two of the major reservoir units are the Dongara Sandstone (oil and gas) and the Kingia Sandstone (gas).
