The project is currently in feed stage and is expected to start commercial production in 2025. Final investment decision (FID) of the project will be approved in 2023. The development cost is expected to be $459 m. The Trefoil conventional gas development will involve the drilling of approximately six wells and includes wellhead platform.

Field participation details

The field is owned by Beach Energy and Oil and Natural Gas.

Production from Trefoil

Production from the Trefoil conventional gas development project is expected to begin in 2025 and is forecast to peak in 2026, to approximately 1,707 bpd of crude oil and condensate and 57 Mmcfd of natural gas. Based on economic assumptions, the production will continue until the field reaches its economic limit in 2051.

Remaining recoverable reserves

The field is expected to recover 27.61 Mmboe, comprised of 3.87 Mmbbl of crude oil & condensate and 142.45 bcf of natural gas reserves.
