Groundwater modelling and predictive analysis
This project will undertake independent groundwater modelling and predictive analyses to inform coal seam gas (CSG) groundwater impact assessment and regulatory monitoring and management in the Narrabri Gas Project (NGP) area.
The study will address community concerns about potential groundwater impacts to the Great Artesian Basin (GAB) aquifer – the Pilliga Sandstone and Namoi alluvial aquifers including groundwater losses induced by depressurization of coal seams in the underlying Gunnedah Basin.
Better understanding of ground flow systems and water balance of the alluvial and the GAB aquifers and their connectivity are crucial for assessing and managing impacts from coal seam gas depressurization in the Gunnedah Basin formations.
The improved modelling framework will help to estimate aquifer water balance under baseline development and future conditions including cumulative impacts and climate change effects.

Groundwater modelling and predictive analysis to inform CSG impact assessment, monitoring and management
This fact sheet describes CSIRO research project activities relating to independent groundwater modelling and predictive analyses in the Narrabri region of New South Wales. These analyses will help improve the understanding of groundwater flow in alluvial and Great Artesian Basin aquifers. Results will inform coal seam gas (CSG) groundwater impact assessment, regulatory monitoring and groundwater resource management.
