A new geomechnical tool for the evaluation of hydrocarbon trap integrity. Hydrocarbon exploration drilling is an intrinsically high risk, high cost activity. Even once a potential reservoir is located there remains the possibility that under recent geological activity the trap has become breached and leaked due to failure of overlying or adjacent rock. This Project will develop a technique that builds on current predictive techniques, and numerical modelling methods, to produce a series of sub-s ....A new geomechnical tool for the evaluation of hydrocarbon trap integrity. Hydrocarbon exploration drilling is an intrinsically high risk, high cost activity. Even once a potential reservoir is located there remains the possibility that under recent geological activity the trap has become breached and leaked due to failure of overlying or adjacent rock. This Project will develop a technique that builds on current predictive techniques, and numerical modelling methods, to produce a series of sub-surface geomechanical models for four important petroleum basins. This new and integrated geomechanical approach will improve current predictive capabilities for detecting breached traps, thus enhancing prospectivity in the major petroleum provinces of Australia.Read moreRead less
Flue Gas and CO2 Geosequestration in Surat and Bowen Basin Coals. Climate change considerations require that CO2 emissions to atmosphere be severely reduced. This is best done in the short term by permanently storing the CO2 underground. Amongst the cheapest and safest options are to use coal seams, which then release valuable methane. The market value of this extra methane is ~$9billion and this reduces the cost of sequestration from ~$56 to $25/t CO2. Coal has a very strong affinity for CO2, ....Flue Gas and CO2 Geosequestration in Surat and Bowen Basin Coals. Climate change considerations require that CO2 emissions to atmosphere be severely reduced. This is best done in the short term by permanently storing the CO2 underground. Amongst the cheapest and safest options are to use coal seams, which then release valuable methane. The market value of this extra methane is ~$9billion and this reduces the cost of sequestration from ~$56 to $25/t CO2. Coal has a very strong affinity for CO2, so flue gas stream from power stations can be injected directly, eliminating the need for equipment to capture the CO2, providing savings of ~$500million for each large power station.Read moreRead less
Computational Rock Physics. Knowledge of the quantitative relationships between rock and fluid properties, and seismic characteristic is necessary to improve the determination of fluid saturation and accurately monitor recovery of oil and gas. The proposed project aims to develop these relationships by teaming up two Australian-based experts in 3D seismic image analysis and theoretical rock physics, with a global company at the forefront of the industry. Developing these relationships will be a ....Computational Rock Physics. Knowledge of the quantitative relationships between rock and fluid properties, and seismic characteristic is necessary to improve the determination of fluid saturation and accurately monitor recovery of oil and gas. The proposed project aims to develop these relationships by teaming up two Australian-based experts in 3D seismic image analysis and theoretical rock physics, with a global company at the forefront of the industry. Developing these relationships will be a cutting edge research achievement, will directly impact on exploration, interpretation and production decisions within the oil and gas industry in Australia and globally, and greatly advance Australia's reputation as a leader in petroleum research services and training.Read moreRead less

Key contributions will be made to the science that underpins petroleum recovery. The combination of diverse expertise in interfacial physics and chemistry, petroleum geology and petrophysics provides a large innovative potential for the industry. Two graduate students will be educated in a rich multi-disciplinary research environment with a strong emphasis on both academic and industrial aspects of the problems. The research conducted will enable the industrial partners to improve existing technologies for predicting where oil and gas is trapped and for petroleum recovery.

The Effect of Fines Particles on Production and Permeability of cbm Reservoirs. Coalbed methane (cbm) energy resources in Australia exceed $20b in value. One of the production issues with recovering cbm is fines that are created or exist in the coal, which block gas flow to the recovery wells and damage downstream equipment. Understanding how fines are created and migrate within gas wells and then overcoming this problem, the purpose of this research, could deliver additional gas production wort ....The Effect of Fines Particles on Production and Permeability of cbm Reservoirs. Coalbed methane (cbm) energy resources in Australia exceed $20b in value. One of the production issues with recovering cbm is fines that are created or exist in the coal, which block gas flow to the recovery wells and damage downstream equipment. Understanding how fines are created and migrate within gas wells and then overcoming this problem, the purpose of this research, could deliver additional gas production worth over $1.8billion and reduce maintenance costs related to cbm extraction by $25m per year.Read moreRead less
Dynamic Gas Permeability Investigations of Highly Stressed Coals. Coal Bed Methane (CBM) is an emerging energy resource in Australia, which has multi-billion dollar CBM reserves. Gas is clean burning, produces little greenhouse gas and almost no disruption to surface activities (like farming) during extraction. These environmental benefits, with low cost, make gas the fuel of choice for power and heat worldwide. This project seeks to assist development of CBM engineering from deep coal seams.

Gas is clean burning, produces little greenhouse gas and almost no disruption to surface activities (like farming) during extraction. These environmental benefits, with low cost, make gas the fuel of choice for power and heat worldwide. This project seeks to assist development of CBM engineering from deep coal seams. These contain the most gas, but are technically more difficult to develop than shallower reservoirs. In particular, it examines how natural and induced stress fields can be used to improve productivity, by understanding the relationships between different coal types, their environment and gas production rate.Read moreRead less
