The petroleum industry progressed significantly to develop 3D/4D geomechanical models (GMs) to make efficient field development planning which reduces the uncertainty of 1D GM in the field scale. In this paper, we demonstrated how to build a high-res...

The Gonneville deposit is a significant new PGE-nickelcopper-cobalt-gold sulphide deposit discovered by Chalice Mining in 2020. Located only 70 km northeast of Perth, Western Australia, it represents the first major discovery of a PGE-rich orthomagma...

Knowledge of the present-day stress is important to understand the dynamics of earthquakes, and to manage the safe and sustainable usage of the underground during storage and exploitation. Eastern Australia hosts several sedimentary basins with large...

Geoscience Australia (GA) and its predecessors have been conducting geophysical surveys and processing geophysical data since the early 1950’s. Over time, GA’s role has changed from being a pioneer in the acquisition and processing of data to foc...

It is often assumed that velocities associated with good quality seismic images can be directly used for time-to-depth conversion, pore-pressure prediction or even as a driver for seismic amplitude interpretation. However, such applications require s...

‘Hotspot’ geophysical exploration has passed its zenith. In areas like New Brunswick, where this exploration style has been successful, deposits with a more complex signature have been left behind. Using improved computational power and geophysic...

MagnetoTelluric (MT) time series datasets are expensive to acquire, can be high volume (100s of terabytes), and the time taken to publish (measured from collection to release) often takes more than two years. Time series datasets have been notoriousl...

It is generally accepted that improvements in mineral exploration are required to meet the rising demand for minerals associated with a transition to lower carbon energy sources. There is growing consensus in mineral exploration that the distribution...

Interpretation of the nature and extent of basement rocks in many regions is hampered by lack of exposure and because potential field data tend to reflect the signatures of overlying upper crustal units, highlighting the need for tools that image dee...

The Papuan Fold and Thrust Belt (PFTB) in Papua New Guinea hosts the prolific Papuan Basin petroleum system yet remains underexplored compared with other fold and thrust belts worldwide. The underexplored nature of the PFTB results from its remotenes...

Iron oxide-copper-gold (IOCG) systems, in a broad geophysical sense, include a spectrum of mineralisationstyles ranging from reduced, pyrrhotite-dominant examples, sometimes referred to as iron sulphide coppergold (ISCG) systems, to magnetite-pyrite ...

Full waveform refraction imaging with the common intercept gather (CIG) is a simple application of the stacking procedures routinely employed with seismic reflection data processing to the standard intercept time method. Accordingly, the stacked full...

Various types of igneous rocks have been frequently encountered during hydrocarbon exploration of sedimentary basins along rifted passive margins, and their impacts on hydrocarbon maturation and migration processes are diverse. Buried volcanoes gener...

Full-waveform inversion (FWI) uses the complete seismic wavefield (transmitted, reflected and converted waves) to build the models of subsurface physical properties. We conducted a feasibility study of a 2D elastic FWI applied to the synthetic and fi...

Exploration in Australia’s Beetaloo Sub-basin focuses on the liquids, wet-gas, and dry-gas mature shales of the Kyalla and Velkerri formations. Gas storage in these reservoirs occurs as free gas and additionally through adsorption to the internal p...

Spatial modelling of analysis results such as grade, geochemical properties and density is required for resource estimation in almost all commodities. For spatial modelling of most commodity properties, geostatistical methods are the most popular bec...

This paper presents a case-study of the application of facies-based seismic inversion in the Cooper-Eromanga Basin, South Australia. The technique has been used to support the development of shallow gas fields in the Cretaceous reservoirs of the Coor...

Here we present 3D and 2D resistivity models of the lithosphere beneath an area of southeast Australia, derived from the Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) and a subsequent infill broadband MT transect collected in...
