The Late Jurassic Springbok Sandstone in the Surat Basin, Australia, is highly heterogeneous in terms of lithology and hydrogeological properties. This heterogeneity is poorly defined in well logs, due, in part, to clay phases that do not exhibit …

Newly acquired high-quality data are being used to reinterpret the Surat Basin flow systems of the Great Artesian Basin (GAB) in Australia. This paper revisits and updates previous interpretations of flow in the Hutton Sandstone with detailed …

In order to assess the impact of faulting on the production and compartmentalisation of a coal seam gas (CSG) reservoir, seismic reflection surveys and subsequent drilling were undertaken to locate and then intersect the Horrane Fault in the …

The geological basins in Australia across which the hydrogeological Great Artesian Basin (GAB) exists, hold significant coal and coal seam gas (CSG) resources. Resource development from deep sedimentary basins often involves the risk of impacting …

The Precipice Sandstone is a major Great Artesian Basin aquifer in the Surat Basin, Queensland, Australia, which is used for water supply and production of oil and gas. This report describes use of observed groundwater pressure responses to …

Coal seam gas (CSG), or coal bed methane, developments in sedimentary basins such as the Great Artesian Basin (GAB) in Australia, have the potential to impact on aquifers overlying and underlying the target coal formations. The extent to which …

Dalhousie Springs is the largest spring complex in the western Great Artesian Basin (GAB), Australia. Aridland springs like Dalhousie provide the only aquatic habitats in regions lacking surface water and are globally threatened by unsustainable …

Quantitative field methods were used to refine eco-hydrogeological conceptual models of terrestrial groundwater dependent ecosystems (GDEs) in the Great Artesian Basin (GAB), Queensland, Australia. There are few studies which report on the …

The western Great Artesian Basin (GAB) is an important water source for pastoral and town water supplies, as well as for springs containing endemic flora and fauna, within arid Australia. This study focuses on the hydrochemical variations of …

Understanding groundwater use, both current and historical, is important for understanding the hydrogeology of groundwater systems, and for water planning. The Queensland portion of Australia’s Great Artesian Basin (GAB) is managed under the Water …

Water sampling at springs that are a part of the Freeling Spring Group, South Australia, was used along with electrical resistivity imaging (ERI) data to evaluate the sources and pathways for groundwater to the springs and to find evidence of …

A defined hydrogeological basin is convenient for understanding and classifying groundwater systems. However, groundwater flow results generally from pressure and density gradients and may pass through boundaries defined by hydrostratigraphy.

The effective deep recharge to the Hutton Sandstone, a major confined aquifer of the Surat Basin, Australia, has been quantified for the first time with the aid of environmental tracers. A factor of ten discrepancy was found when deriving …

Monitoring is critical for effective groundwater management, especially in systems with competing groundwater interests, such as the Great Artesian Basin’s (GAB) Surat Basin (~180,000 km2) in Queensland, Australia. Coal seam gas (CSG) activities …

In certain areas, key aquifers of the Great Artesian Basin (GAB), Australia, are experiencing continued declining water-level trends. This has been accompanied by heated conflicts between water users and a lack of trust in governance arrangements …

The Great Artesian Basin (GAB) in Australia underlies semi-arid and arid regions across 1.7 million km2 or one-fifth of Australia. The basin’s groundwater resources were discovered around 1880 and their development allowed pastoral activities …

The relationship between fault structures and Great Artesian Basin (GAB) spring occurrence has rarely been discussed in relation to intra-plate seismicity. This is despite the occurrence of mound springs in the southwest portion of the GAB in …

Justin Francis Costelloe (Fig. 1 ) was born in 1965. He grew up in the mining city of Bendigo (Victoria, Australia) before studying Earth Sciences at the University of Melbourne. He went on to work as an exploration geologist in the mining industry …

The Great Artesian Basin (GAB) in Australia is one of the largest aquifer systems in the world and it supports a range of agriculture, industry, fragile ecosystems, and townships. Climate variability and future projections of climate change will …

Derangement of surface drainage systems across central and eastern Australia testify to subtle tectonic modification of the landscape on the million-year timescale that is relevant to groundwater residence in the Great Artesian Basin (GAB). In the …
