The model domain covers an area of 215 km × 285 km (Fig. 1) in the central part of the Galilee Basin. The selection of the boundaries of the model domain is guided by data availability, i.e. areas where seismic surfaces are available (they do not extend beyond the northern limit of the chosen model domain).
In addition, the model domain MAPK inhibitor is restricted to the central-northern part of the Galilee Basin as the southern part of the basin is not expected to hold exploitable or economic amounts of CSG due to the indicated absence of coal seams in the Aramac Coal Measures and Betts Creek Beds correlatives. Following are details of the parameters incorporated into the model. All the data sources used during the model development are listed in Table 1. This process is a key step in any geological model because the confidence of the final model relies on it. Well log data were verified DAPT price in order to standardise stratigraphic unit names. This process involved the revision of the wire-line data and lithology of every well in order to identify appropriate stratigraphic units. The stratigraphy and wire-line log characteristics of the Palaeozoic formations within the Galilee Basin used during the revisions were defined by Gray and Swarbrick (1975), and for the Triassic formations by Green et al. (1997). In the Eromanga Basin, wire-line log characteristics
were defined by Gray et al. (2002). The stratigraphic unit names used here correspond with those currently formally recognised by Geoscience Australia (Geoscience Australia and Australian Stratigraphy Commission, 2014). Many old groundwater bores were logged before the current stratigraphic classification of units for both basins existed. An extensive data quality check was carried out on lithological and stratigraphic
logs for these drillholes prior to the commencement of the modelling process. An example of this is the exploration well Saltern Creek 1 (Fig. 2), where 14 of 16 logged units were modified during the present study (Fig. 3). Logs in this well had been defined by Mott and Associates Pembrolizumab (1964), according to old stratigraphic names or names belonging to neighbour basins (Cooper, Bowen and Surat basins). Groundwater bores from the DNRM database were not incorporated in this study because of the lack of reliable stratigraphic information. For example, although more than 1600 bores are registered in the DNRM groundwater database (DNRM, 2012) within the 3D geological model domain, less than the 10% of these have available stratigraphic information. In addition, the data quality of these remaining 10% is often poor, or the stratigraphic data of these bores are already contained in the QDEX database, as many of the groundwater bores are old exploration wells registered in QDEX that were later converted to groundwater bores.
