This preliminary report will provide a geochemical and ionic characterisation of groundwater, to determine baseline conditions and, if possible, to distinguish between different aquifers in the Laura basin. The groundwater quality data will be compared against the water quality guidelines for aquatic ecosystem protection, drinking water use, primary industries, use by industry, recreation and aesthetics, and cultural and spiritual values to assess the environmental values of groundwater and the treatment that may be required prior to reuse or discharge.

The cartographic collection of the Doc Fisher Geoscience Library consists of the maps and air photos created or acquired by agency staff since the formation of BMR in 1946. This includes maps produced by agencies which have merged with these over the years, such as AUSLIG. Maps held include: Australian geological map series (1:250,000, 1:100,000 and the 1 mile series); topographic maps produced by NATMAP and its predecessors (1:250,000, 1:100,000 and 1:50,000) - latest editions only; various Australian geochemical, geophysical and other thematic maps; geoscience map series from other countries acquired on an exchange basis, including some with accompanying explanatory notes; Non-series maps acquired by donation or exchange; atlases. The Air photos are predominantly those used for mapping Australia and, to a lesser extent, Papua New Guinea and Antarctica, by BMR/AGSO from the 1940s to the 1980s. Geographical coverage of the sets is not complete, but many individual photos are unique in that they have pin points, overlays or other markings made by teams in the field. The Papua New Guinea photographs in the collection may, in many cases, be the only existing copies. Flight diagrams are also held for many (but not all) sets of air photos. Some other related materials, such as montages of aerial photographs (orthophotos), are also represented in the collection.

This map is part of a series which comprises 50 maps which covers the whole of Australia at a scale of 1:1 000 000 (1cm on a map represents 10km on the ground). Each standard map covers an area of 6 degrees longitude by 4 degrees latitude or about 590 kilometres east to west and about 440 kilometres from north to south. These maps depict natural and constructed features including transport infrastructure (roads, railway airports), hydrography, contours, hypsometric and bathymetric layers, localities and some administrative boundaries, making this a useful general reference map.

A regional assessment of the Petrel Sub-basin has identified Mesozoic formations highly prospective for CO2 storage. The CO2 storage play comprises the Lower to Middle Jurassic Plover Formation and Lower Cretaceous Sandpiper Sandstone reservoirs, which are sealed by the Late Jurassic Frigate Formation and Cretaceous Bathurst Island Group respectively; the latter forming the regional seal.   The study comprised a sequence stratigraphic approach through the integration of biostratigraphic, well log and seismic data to produce a new stratigraphic framework. Lithological, laboratory, petrophysical and seismic data were utilised to identify facies, with a focus on reservoir quality and sealing capacity for geosequestration. It was concluded that the reservoirs were generally good quality and across the basin overall there were effective seals. A series of palaeogeographic maps summarise this geological and geophysical data, which was utilised for geological models and 3D dynamic simulation models. A fault study and geological modelling indicate that major faults do not affect the containment prospects of the total storage play; this conclusion can also be applied to salt diapirism.   This multi-disciplinary geological assessment has identified several CO2 storage prospects due to their good reservoir and sealing potential, which will be described in this presentation.
