The moratorium, previously scheduled to end on December 31, will allow for the review and strengthening of existing standards for fraccing in NSW, as well as the development of technical guidelines.

Industry experts and NSW Chief Scientist and Engineer, Professor Mary O'Kane, will review the fraccing standards prior to implementation.

Resources and Energy Minister Chris Hartcher said the government recognised the community's concern over the potential for polluting aquifers by the coal seam gas industry as part of the fraccing process.

"That's why we're proceeding with caution and making sure the proper frameworks are in place for the protection of our aquifers, our environment and our prime agricultural land," he said.

The review is considering local material with a particular focus on Queensland, as well as overseas standards in the US and Canada.

The government is also currently reviewing the standards for coal seam gas well integrity to ensure all activity is contained within the well and to prevent the potential escape of any gases or liquids.

"This review is addressing the health, safety and environmental risks associated with the loss of well integrity and covers conventional onshore petroleum activities as well as onshore coal seam gas activities in NSW," Mr Hartcher said.

"The NSW Government is working to ensure we have world's best practice in well integrity, design and fraccing standards.

"We are working very carefully to strike the right balance between resource development, continued agricultural production and environmental protection while meeting the State's future energy needs."
