UWIR report cover

Current Surat UWIR

The Underground Water Impact Report 2021 for the Surat Cumulative Management Area came into effect on 1 May 2022. It reports on the assessment and management of cumulative impacts from coal seam gas, coal mining and conventional oil and gas development in the Surat and southern Bowen basins.

Research update papers and technical notes

OGIA’s research program is guided by the need to improve the assessment for each successive UWIR and to address emerging issues from stakeholders. OGIA’s current research focus areas are:

  • Groundwater flow modelling – ongoing improvements by testing and developing new and innovative approaches and methods that are specifically suited to impact assessment.
  • Subsidence – improved understanding of subsidence from the monitoring data across the Surat Basin and refinement of modelling techniques.
  • Monitoring and trend analysis – development and testing of new monitoring techniques and ongoing analysis of additional groundwater monitoring data to identify impacts associated with CSG development.
  • Hydrogeological conceptualisation – targeted assessment for improving understanding of groundwater connectivity.
  • Groundwater-dependent ecosystems – integration of groundwater assessment with processes that affect groundwater conditions around the connected ecosystems.

OGIA has started publishing research update papers and technical notes, instead of technical reports, to present findings and progress on specific pieces of research work. These reflect the best data and information available at the time.
