  • The Great Artesian Basin Water Resource Assessment (the Assessment) provides an analytical framework to assist water managers in the Great Artesian Basin (GAB) to meet National Water Initiative commitments. This report presents the findings of the Assessment for the Surat region - one of four reporting regions in the Assessment, including the Surat, Central Eromanga, Western Eromanga and Carpentaria regions.

  • Applications dated 18 August 2010 for verification of a reference standard of measurement under Regulation 12 of the National Measurement Regulations 1999 was received from the Land and Property Management Authority, NSW for verification of GDA94 position on their CORSnet monuments. This report documents the processing and analysis of GPS data observed by the CORSnet-NSW GPS stations during a 7-day period from 08 August to 14 August 2010 (day of year 220 to 226) for 4 stations (CSNO, IHOE, PBOT, and TBOB) to satisfy the position verification requirements.

  • This record presents a compilation of new zircon U-Pb SHRIMP geochronological results (total of 17 samples) from the east Arunta region, the Litchfield Province and the Nimbawah Domain of the Pine Creek Orogen, and the Murphy Inlier, Northern Territory/Queensland. These data was collected through the ongoing collaborative NTGS-GA geochronology project during the period July 2007-June 2009 under the National Geoscience Agreement (NGA). Six samples were analysed from the east Arunta region (HALE RIVER, ILLOGWA). Five of these samples were from Palaeoproterozoic metasediments and intrusives, one sample (1945963) was from the overlying Neoproterozoic Amadeus Basin (Table 1). Ten samples in total were collected from the Pine Creek Orogen; one from the Litchfield Province (CAPE SCOTT), the remainder from the Nimbuwah Domain (COBOURG PENINSULA, ALLIGATOR RIVER). One sample (from the base of the Westmoreland Conglomerate) was analysed from the Murphy Inlier region (WESTMORELAND; Qld). Three additional samples were submitted for SHRIMP analysis but which did not yield zircons or the zircons extracted were unsuitable for analysis.

  • This report provides background information about the Ginninderra controlled release Experiment 1 including a description of the environment and weather during the experiment, the groundwater conditions and a brief description of all the monitoring techniques that were trialled during the experiment. Release of CO2 began 28 March 2012 at 10:30 AM and stopped 30 May 2012 4:15 PM. The total CO2 release rate during Experiment 1 was 144 kg/d CO2. Krypton gas was also released as a tracer gas at a rate of 10 mL/min Kr in one section of the release well only. The aim of the Ginninderra Experiment 1 controlled release was to artificially simulate the leakage of CO2 along a line source, to represent leakage along a fault. Multiple methods and techniques were then trialled in order to assess their abilities to: - detect that a leak was present - pinpoint the location of the leak - identify the strength of the leak - monitor how the CO2 behaves in the sub-surface - assess the effects it may have on soil ecology Several monitoring and assessment techniques were trialled for their effectiveness to quantify and qualify the CO2 that was release. The methods are described in this report and include: - soil gas - CO2 carbo-cap (GMP343) - eddy covariance - groundwater levels and chemistry - soil microbial samples - soil flux - krypton in air - electromagnetic (EM-31) - meteorology - CO2 isotopes in tank This report is a reference guide to describe the Ginninderra Experiment 1 details. Only methods are described in this report with the results of the study published in conference papers and future journal articles.

  • Basin evolution of the Vlaming Sub-basin and the deep-water Mentelle Basin, both located offshore on the southwest Australian continental margin, were investigated using 2D and 3D petroleum system modelling. Compositional kinetics, determined on the main source sequences, were used to predict timing of hydrocarbon generation and migration as well as GOR evolution and phase behaviour in our 2D and 3D basin models. The main phase of petroleum generation in the Vlaming Sub-basin occurred at 150 Ma and ceased during following inversion and erosion episodes. Only areas which observed later burial have generated additional hydrocarbons during the Tertiary and up to present day. The modelling results indicate the likely generation and trapping of light oils for the Jurassic intervals for a variety of structural traps. It is these areas which are of greatest interest from an exploration point of view. The 2D numerical simulations in the Mentelle Basin indicate the presence of active hydrocarbon generating kitchen areas. Burial histories and generalized petroleum evolutionary histories are investigated.
