CSG companies and the Queensland Government collect data about the volumes of various types of groundwater use. This data helps estimate groundwater extraction volumes used in groundwater models which inform decisions regarding the management of the industry and plan water allocations. For example, the Queensland Government model is used to identify which private water bores are likely to have declining groundwater levels as a result of CSG industry activities and compensation for water loss is negotiated between the companies and...

CSG companies and regulatory agencies use geological models in decision-making processes regarding the industry. The geological models used by each organisation can vary based on data availability and interpretation and are often focus on specific locations relevant to company operations. This project aims to develop a consistent and unified Surat Basin framework model to provide an improved shared understanding of the geology of the basin. It will provide a regional scale reference model for all users. This model will be...

A technical feasibility study was completed to determine if there is sufficient groundwater quality data available to develop a Water Chemistry Atlas with the capability to address key technical questions regarding regional water quality trends and provide valuable information to government, industry and the community. Key steps included: Developing a test database structure for the Atlas and use of a subset of data from the Office of Groundwater Impact Assessment (OGIA) water quality database for trial purposes. using a range...

Pressure dependent permeability (PDP) and stress dependent permeability (SDP) behaviour have been exhibited in Surat and Bowen Basin coal measures. Anecdotal and purported evidence from some areas indicates that this is generally a function of coals drawdown rates or observed more often in coals with higher permeability anisotropy. This project will define evidenced behaviour in terms of coal properties or variables using data analytics and analytical tools with production. Models will be developed to describe or methods to optimise or...

Reliable characterisation of natural fracture networks can improve management of tight gas reservoirs typical of onshore Australia. The Goonyella Riverside coal mine in the northern Bowen Basin provides an analogue study for the development of natural fracture systems in a mildly thrusted Permian coal measure succession. A total of 3,862 m of image log data from 18 closely spaced wells was integrated with 3D seismic data and outcrop observations to characterise structural style and natural fracture development at Goonyella Riverside...

The Indo-Australian plate (IAP) is unique when compared to most other plates in that the maximum in situ horizontal stress (sHmax) orientation is not uniform and does not parallel the direction of absolute plate velocity. Consequently, the Australian continent provides an ideal setting to study the interaction between tectonic forces and the in situ stress field. The focus of this thesis is on improving current knowledge of the in situ stress field of the Australian continent, largely through the compilation...
The analysis consolidates existing knowledge about the mineralogical, hydrogeological and geochemical properties of these formations and provides new information about their distinguishing chemical features. The findings provide an enriched understanding of baseline conditions in these formations, and will be invaluable in the design and interpretation of future groundwater monitoring activities. A new database, which integrates all publicly available groundwater quality data for Queensland (as at March 2011) was constructed as part of this activity.

The objective of this project is to better understand the influence of geological structures on regional groundwater flow dynamics. The project will draw upon existing information and employ a variety of techniques aimed at identifying and assessing new geological structures as well as assessing current structural mapping and its potential influence on groundwater flow. The initial phase of the project will involve updating the mapping of geological structures and a preliminary assessment of inferred hydraulic characteristics of those structures.

The objective of this project is to develop improved methodologies for the modelling of regional groundwater impacts caused by CSG water extraction in coal seams and surrounding aquifers. Outputs from the project will guide the development of the next regional groundwater flow model which will be constructed to support the revision of the UWIR in December 2015.

Improved understanding of the risk to springs requires improved understanding of spring function. Conceptual options for the hydrogeological setting of representative springs have been developed and field data is being collected to refine understandings. Spring monitoring methodologies are being reviewed and a field trial is currently being designed.
