Improved hydrogen geological storage via zeta potential measurements. Hydrogen is a clean fuel which has the potential to revolutionize the energy supply chain by complete decarbonisation. An estimated 50-fold increase in the global hydrogen market is expected by 2050, totalling AUD$16.3 trillion. However, the key barrier to a hydrogen economy is hydrogen storage, as hydrogen is highly volatile, compressible and flammable. Underground hydrogen storage, i.e. storage of hydrogen in sedimentary geo ....Improved hydrogen geological storage via zeta potential measurements. Hydrogen is a clean fuel which has the potential to revolutionize the energy supply chain by complete decarbonisation. An estimated 50-fold increase in the global hydrogen market is expected by 2050, totalling AUD$16.3 trillion. However, the key barrier to a hydrogen economy is hydrogen storage, as hydrogen is highly volatile, compressible and flammable. Underground hydrogen storage, i.e. storage of hydrogen in sedimentary geologic formations, is a potential option to solve this problem. In this project we will provide fundamental data required to establish hydrogen underground monitoring techniques, and to develop associated large-scale models with which underground hydrogen storage efficiency and security can be predicted.Read moreRead less
Pore scale characterisation of the wettability of petroleum reservoir core material: Towards optimised recovery of hydrocarbon reserves. In most oil reservoirs more than 50% of original oil in place remains unrecovered. A major factor contributing to suboptimal recovery is insufficient knowledge of the rock wettability. Even a small improvement in recovery will have substantial economic benefit. The proposed project aims to characterise wettability in hydrocarbon bearing rocks using advanced 3D ....Pore scale characterisation of the wettability of petroleum reservoir core material: Towards optimised recovery of hydrocarbon reserves. In most oil reservoirs more than 50% of original oil in place remains unrecovered. A major factor contributing to suboptimal recovery is insufficient knowledge of the rock wettability. Even a small improvement in recovery will have substantial economic benefit. The proposed project aims to characterise wettability in hydrocarbon bearing rocks using advanced 3D imaging hardware and understand implications to oil displacement and recovery via state-of-the-art computational tools. Scientifically, this will be a leading edge research achievement enhancing Australian competitiveness in petroleum engineering research and will help Australia become a world leader in the export-oriented petroleum research services industry.Read moreRead less

Australia's oil and gas reserves are primarily dependent on exploration and development in remote offshore deep waters where the operational costs are highest. This is precisely the area where the emerging microtomography-based network model technology will have the most economic impact. The outcome will be of immense scientific interest to the national/international community which has long been studying network models to understand multiphase flow in petroleum reservoirs. This will place Australia in the forefront of this technology. Furthermore, modelling studies of groundwater remediation and geosequestration of greenhouse gases which require a multiphase model will benefit from the project.Read moreRead less

It has the strength to place Australia in the forefront of these technologies. Read moreRead less
Mudstones as methane sources: gas production from coal seam interburden. Carbonaceous mudstones associated with coal measures already exploited for gas present an attractive reservoir of methane. This project seeks to provide methods for accessing this gas. Mudstone associated with coal seam gas developments are very extensive and gas quantities may exceed even that in the coal itself. Further infrastructure and access permits are already in place for coal seam gas recovery. Unlike shale, which ....Mudstones as methane sources: gas production from coal seam interburden. Carbonaceous mudstones associated with coal measures already exploited for gas present an attractive reservoir of methane. This project seeks to provide methods for accessing this gas. Mudstone associated with coal seam gas developments are very extensive and gas quantities may exceed even that in the coal itself. Further infrastructure and access permits are already in place for coal seam gas recovery. Unlike shale, which is fissile, mudstone is much softer, more malleable and plastic, and consequently will respond abnormally to hydraulic fracturing and propping, so new methods proposed to be developed in this project are needed for stimulation.Read moreRead less
Managing Fresh-Water Resources in Saline Environments. Australian industry and urban developments often rely on a secure supply of fresh water. In many situations, the fresh water occurs adjacent to large expanses of saline water. This poses special constraints on how the fresh water can be recovered. This project undertakes careful mathematical modelling of fresh water recovery from reservoirs and from within islands (where it may be the only practical source of drinking water). The injecti ....Managing Fresh-Water Resources in Saline Environments. Australian industry and urban developments often rely on a secure supply of fresh water. In many situations, the fresh water occurs adjacent to large expanses of saline water. This poses special constraints on how the fresh water can be recovered. This project undertakes careful mathematical modelling of fresh water recovery from reservoirs and from within islands (where it may be the only practical source of drinking water). The injection and extraction of ground water in novel "mineral leaching" mining technology will also be investigated.Read moreRead less
Mobile and rapid nuclear magnetic resonance characterisation of oilfield emulsions. Oilfield emulsions, which can severely disrupt crude oil production, require droplet sizing in order to enable separation of the emulsified water. This project will provide this measurement capability based on Nuclear Magnetic Resonance techniques, as are frequently used for chemical identification and medical diagnostics.

This project aims to develop a robust classification method for reservoir rock incorporating static, dynamic and mechanical attributes via multiscale digital core analysis using the concept of regional measures. Rock-types are used to populate reservoir models in a sophisticated routine of geological classification, spatial modelling and uncertainty analysis. Introducing high-resolution rock-types incorporating hydraulic properties and compaction allows the development of a new generation of reservoir simulators. The project aims to derive a consistent high-resolution definition of rock-types incorporating compaction for petrophysical, geological and reservoir engineering purposes. This would greatly enhance our capacity to develop thinly layered reservoirs with direct applications in 4-D seismic reservoir characterisation and the development of unconventional reservoirs.Read moreRead less
