Beetaloo basin shale long-term competency after decommissioning
Improved understanding of how decommissioned wells in the Beetaloo basin maintain their integrity over the long-term is important for Northern Territory community groups, government regulators and industry.
This project aims to quantify the self-sealing competency of shales in the Beetaloo basin that sit between the deep target natural gas shale formations and the shallow Cambrian Limestone Aquifer.

Beetaloo Basin shale long-term competency after decommissioning
This final report describes the methods and results of a CSIRO research project designed to assess the ability of shale formations in the Beetaloo Sub-basin to self-seal or ‘creep’ over time after gas well decommissioning, creating a natural barrier to movements of hydrocarbon fluids. This phenomenon would significantly reduce the risk of contaminants entering the environment.
