Between 3 May 2012 to 24 June 2012 Geoscience Australia undertook two major surveys off the coast of the Northern Territory in the Petrel Sub-Basin. The data acquisition was funded through the National Low Emissions Coal Initiative (NLECI) and the Petrel Sub-basin was selected in particular as it has been identified as a prospective area for CO2 storage. One of these surveys, GA336 acquired 4091 kilometres of 2D seismic reflection data. Following on from the completion of the seismic processing of this data was further investigative work investigative work such as this analysis. Four prime lines, GA336-107, 110, 205 and 207 along with the well logs, Flat-Top1, Petrel 1A and Petrel 4 were selected for further 2D Simultaneous Inversion and Rock Physics Modelling. Previous Pre Stack Depth Migration had been undertaken on these lines and the PSDM Angle Stacks were imported along with the relevant horizon interpretation into the Jason integration algorithms.

Currently there is no uniform methodology to estimate geological CO2 storage capacity. Each country or organization uses its own evaluation and estimation method. During 2011-2012, the International Energy Agency has convened a process among national geological survey organizations to recommend a common estimation method for countries to use. Such a method should describe a typical process for developing assessments of CO2 storage resources; recommend a sound methodology for arriving at a jurisdictional or national-scale CO2 storage resource assessment that could be applied globally; and recommend a way forward to bridge the gap between such a resource and a policy-makers aspiration to understand what proportion of the resource can be relied on and is likely to be technically accessible at any particular cost. This report will outline a 'roadmap' to address these recommendations in a way that jurisdictions can use extant methodologies or craft their own to assess their CO2 storage endowment in a manner consistent with other jurisdictions. In this way they may be able to fully utilize their endowment as well as make a contribution to the potential realization of a worldwide estimate of storage resource.

Residual CO2 saturation (Sgr-CO2) is considered one of the most important trapping mechanisms for geological CO2 storage. Yet, standard procedures for the determination of Sgr-CO2 are missing and Sgr-CO2 has not been determined quantitatively at reservoir until recently. This circumstance introduces uncertainty in the prediction of the nature and capacity of CO2 storage and requires the development of well test procedures. The CO2CRC drilled a dedicated well with perforations in a low salinity aquifer of the Paaratte Formation between 1440 - 1447 m below the surface of the Otway Basin, Australia, with the aim to develop and compare five methods to determine Sgr-CO2 (see also Paterson et al, this volume).

The CIAP project Best Available Information System (BAIS) uses a nested grid based on the ICSM map index series from 1:25:000 scale through to 1:1000000 scale tile indices by which statistics for consumed data services are generated and stored. This GIS data set is a key functional component of the BAIS.

The Petrel Sub-basin Marine Environmental Survey GA-0335, (SOL5463) was undertaken using the RV Solander during May 2012, as part of the Commonwealth Government's National Low Emission Coal Initiative (NLECI). The survey was undertaken as a collaboration between the Australian Institute of Marine Science (AIMS) and GA. The purpose was to acquire geophysical and biophysical data on shallow (less then 100m water depth) seabed environments within two targeted areas in the Petrel Sub-basin to support investigation for CO2 storage potential in these areas. This data-set comprises inorganic element data from surface seabed sediments (~0-2 cm) in the Timor Sea.

This is a 3 minute movie (with production music), to be played in the background during the October 28th 2010 Geoscience Australia Parlimentary Breakfast. The video shows a wide range of the types of activities that GA is involved in. These images include GA people doing GA activities as well as some of the results of offshore surveys; continental mapping; eath monitoring etc. The movie will be played as a background before and after GA's CEO (Chris Pigram) presentation.
