On this page you will find current information on production, seismic and drilling statistics for Western Australian onshore and State Waters. With the commencement of the National Offshore Petroleum Titles Administrator (NOPTA) and the National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA) in 2012, the Department of Mines, Industry Regulation and Safety’s responsibility is now limited to Western Australia’s onshore and State Waters.

Reserves and contingent resources
Petroleum reserves in Western Australia have been compiled according to the Society of Petroleum Engineer Petroleum Resources Management System (SPE PRMS). Although we collect all available resources data, we only publish two categories of resources on a basin basis using arithmetic addition:
- Reserves – 1P (Proved) and 2P (Proved plus Probable). Reserves must be discovered, recoverable, commercial, and remaining (at a given date) based on the development projects applied.
- Contingent Resources – 1C and 2C. Contingent resources are estimated at a given date to be potentially recoverable from known accumulations by application of development projects but are not currently commercially recoverable due to one of more of contingencies.
The reserves or contingent resources estimates do not differentiate conventional and unconventional reserves/contingent resources.
