COVID-19 Updates for resources sector: fee relief | To report a serious incident to DEM, as required by Section 85(2) of the Petroleum and Geothermal Energy Act 2000, licensees should contact the serious incident reporting hotline on: (08) 8463 6666. For more information please visit the Compliance and Monitoring webpage | DEM-ERD has just released the first “Basin in a Box” data-package covering the Simpson and Pedirka Basins. The dataset is available via the “Data and Publications” page. Each package is a consolidated set of seismic and well data to facilitate new ventures and exploration assessments of frontier basins in South Australia. Data releases for other frontier basins will follow. | Changes to data submission requirements during COVID-19 restrictions. For further information see here.

The Energy Resources Division of the Department of Premier and Cabinet (DPC-ERD) regulates petroleum and geothermal energy industries under the Petroleum and Geothermal Energy Act 2000 (PGE Act) and the Petroleum and Geothermal Energy Regulations 2013. The regulatory framework is objective based and protects the natural, economic and social aspects of the environment within which activities regulated under the PGE Act are carried out. Key to this objective is the requirement for licensees to adopt and demonstrably implement good practices over the life cycle of their activities and projects.

In the context of well operations well cement integrity is a critical component to achieving one of the key regulatory objectives for the protection of groundwater resources.

To this end, as part of informing the regulatory process DPC-ERD commissioned an independent literature review into the integrity of cement by the University of Adelaide to identify and report on factors that play an important role in the integrity of cement for long term isolation along the entire well life cycle – from engineering design to execution and verification. Information derived from literature together with recommendations are provided in the report.


Critical to cement integrity for the purpose of zonal isolation are:

  • Appropriate design and verification of the placement of cement; and
  • Long term performance of cements.

International studies, hyper-links included below, confirm these findings and conclude that the proper placement of cement is more critical to achieving long term zonal isolation than cement deterioration. Proper placement of cement is achieved by adopting relevant industry standards for cementing design and verification to ensure adverse leakage pathways within the cement sheath and between the cement sheath and casing and/or rock formation are avoided.
