Onshore Royalties

All petroleum and other regulated resources (contained onshore) in South Australia are subject to the provisions as specified in the Petroleum and Geothermal Energy Act 2000 (the Act) and the Petroleum and Geothermal Energy Regulations 2013 (the Regulations). Ownership of all regulated substances remain vested in the Crown until such time as royalty as specified in the Act have been paid to the Crown.

Royalties are calculated as a proportion of the net sales value (excluding GST) at the point of sale to an arms-length purchaser. The value is to exclude allowable expenses in the determination of the wellhead value.

Allowable expenses related to treatment, processing or refining post wellhead, and also include costs associated with conveying the regulated substance to the purchaser. Pre-wellhead costs such as those incurred in exploration, drilling or recovery activities cannot be claimed for the purposes of determining royalty.

Summary of Royalty Provisions

Regulated Substance

Royalty is payable at the rate of 10% of the net post-wellhead sales value (wellhead value) of petroleum recovered at the wellhead.

Wellhead means the casing heads and includes and casing hanger or spool, or tubing hanger, and any flow control equipment up to and including the wing valves.

The wellhead value of petroleum recovered is calculated by deducting from the arms-length gross sales value of petroleum, certain post-wellhead costs.

Post-wellhead costs including operating and depreciation expenses directly relating to treatment, processing and refining post-wellhead, and conveying the petroleum to the point of delivery to the purchaser and may include:

  • an allowance for depreciation of post-wellhead capital assets situated within a production unit on a straight line basis over the life of the field or up to a maximum of 10 years, whichever is the lesser.
  • an allowance for interest on approved post-wellhead capital assets.
  • the net cost of rehabilitation and abandonment of well sites.

Royalty on Geothermal Energy is 2.5% of the wellhead value of the geothermal energy. The value at the wellhead is calculated by subtracting from the sales value, costs reasonably incurred by the producer in getting the energy to the point of delivery to the purchaser (exclusive of GST).

The value at the wellhead of a regulated substance or geothermal energy is to be assessed by the Minister. The Minister may, on application by the producer, or on the Minister's own initiative, review and revise an earlier assessment of the value at the wellhead of a regulated substance or geothermal energy.

Audits are selected in a variety of ways:

* Projects designed to target specific problems or issues in legislation
* Industry trend analysis
* Tip offs

* Follow-up of information received from a variety of sources
* Random selection for the routine verification and coverage of the royalty revenue base

The Resource Royalties Team anticipates that all licensees will be audited at least once every 2 years.

In most cases an auditor will:

* Write, telephone or visit you to let you know that an audit will be conducted
* Explain the process and the scope of the audit
* Specify the records to be produced
* Give you a reasonable period to assemble those records for either submission for desk audit or arranging a time and place to interview you or a representative

* Confirm arrangements in writing

The field audits will be conducted by Authorised Officers appointed pursuant to the Petroleum and Geothermal Energy Act 2000

During an audit, the auditor will conduct interviews and make enquiries to establish compliance with the particular legislation and examine and test some of your internal financial records.

You will receive written advice of the outcome of the audit and any proposed action.

You should ensure that the records the investigator has requested are ready for examination. If you require further time to collate the records, please inform the investigator prior to the commencement of the audit.
