Title: Cumulative impact assessment and management in the Surat Basin: where we are and what we have learned?

Speaker: Sanjeev Pandey - Executive Director, Queensland Office of Groundwater Impact Assessment

Biography:

Mr Pandey is a hydrogeologist with 25 years of public and private sector experience in regional-scale groundwater resource assessment and management. He currently leads the Queensland Office of Groundwater Impact Assessment (OGIA). OGIA is an independent entity for the assessment and management of cumulative groundwater impacts from resource development. Previously as Director of projects in OGIA, he led and completed the development of first cumulative groundwater impact assessment in the Surat and Southern Bowen basins. In his various public and private sector roles, he has been intimately involved in leading technical assessments of the Great Artesian Basin (GAB) and development of strategic policy and legislation for groundwater management in Queensland.

Abstract:

The coal seam gas (CSG) industry has expanded rapidly involving multiple operators in close proximity in the Queensland Surat Basin which is also a sub-basin of the Great Artesian Basin (GAB). CSG production requires reduction in water pressure in the coal seams formation that is sandwiched between the aquifers of the GAB that are of high economic, environmental and cultural value. Reduction in pressure in coal seams has the potential to cause some reductions in water pressure in overlying and underlying aquifers.

Queensland responded to this challenge early by introducing an innovative legislative framework in 2010 for the assessment and management of cumulative groundwater impacts from CSG development. This required an area of intensive CSG development to be declared as a cumulative management area where independent Office of Groundwater Impact Assessment (OGIA) takes the responsibility for undertaking cumulative impact assessment and setting management arrangements which are reported through the underground water impact report. This is done every three years based on an ongoing and adaptive cycle of modelling-reporting-monitoring.

So far OGIA has completed two UIWRs that are underpin by numerous studies on aquifer interconnectivity, groundwater flow dynamics, springs and groundwater flow modelling that, in addition to impact assessment, have made significant contribution in advancing the knowledge of the groundwater flow systems in the Surat sub-basin. The talk will provide an overview of the regulatory framework and some key learnings from this iterative assessment.

The Petroleum and Gas Inspectorate (PGI) is responsible for administering Queensland’s safety and health regulatory framework for activities ranging from petroleum extraction through to household and commercial use.  The PGI conducts an annual program of work as part of its risk-based compliance program.  This is achieved through three proactive activities (engagement, inspections, audits) and three reactive activities (response to enquiries, complaints, incidents). This presentation will cover the regulation of petroleum wells in Queensland predominately focussing on the proactive activities conducted during the 2019/20 financial year.  While this program covered a broad range of topics there was an emphasis on well integrity management and well abandonment.  The results from this work will be discussed along with an outline of future planned work.
