Generally, exploration is carried out under an Exploration Permit but it can also be undertaken under a Drilling Reservation.
A Drilling Reservation is a prospect-size title granted under the Petroleum, Geothermal Energy and Greenhouse Gas Storage Act 1967 (PGEGGSA) that allows drilling and other exploratory operations, such as seismic surveying.
Drilling Reservations are granted for a period up to three years, at the discretion of the Minister for Mines and Petroleum and only where a drillable target has already been identified. Drilling Reservations are not available under the Petroleum and Greenhouse Gas Storage (Submerged Lands) Act 1982.
