Seismic response of partially saturated petroleum reservoir zones: towards quantitative recovery monitoring. In most Australian reservoirs less than 50% of the original oil in place is recovered. A major factor that contributes to low recovery rates is bypassed oil/gas. Even a small, 1% improvement in recovery is of substantial economic significance. The proposed project aims to develop quantitative models for reservoir monitoring of zones with bypassed hydrocarbons using time-lapse (4D) seismic ....Seismic response of partially saturated petroleum reservoir zones: towards quantitative recovery monitoring. In most Australian reservoirs less than 50% of the original oil in place is recovered. A major factor that contributes to low recovery rates is bypassed oil/gas. Even a small, 1% improvement in recovery is of substantial economic significance. The proposed project aims to develop quantitative models for reservoir monitoring of zones with bypassed hydrocarbons using time-lapse (4D) seismic measurements, and thus to improve the hydrocarbon recovery factors. Developing these models will be a cutting edge research achievement, which will make a significant contribution to the knowledge base of the discipline and advance the international reputation of Australian science.Read moreRead less
Seismic attenuation and dispersion in reservoir rocks: broad-band experiments versus theoretical modelling. We propose to develop theoretical models of seismic attenuation and dispersion in hydrocarbon reservoirs, and a new method for experimental testing of these models. These models will provide new information to substantially improve characterisation of hydrocarbon reservoirs from geophysical data. The results will help optimise exploration and improve oil and gas recovery through developmen ....Seismic attenuation and dispersion in reservoir rocks: broad-band experiments versus theoretical modelling. We propose to develop theoretical models of seismic attenuation and dispersion in hydrocarbon reservoirs, and a new method for experimental testing of these models. These models will provide new information to substantially improve characterisation of hydrocarbon reservoirs from geophysical data. The results will help optimise exploration and improve oil and gas recovery through development of new technologies for quantitative reservoir characterisation in Australian basins. This research will enhance Australian competitiveness in basic and applied geophysical research, and will benefit the Australian geophysical industry as a provider of advanced geophysical technologies for oil exploration and production.Read moreRead less
Theoretical and experimental study of elastic properties of porous media permeated by aligned fractures. The aim of the project is to develop a theoretical model for the elastic properties of fractured porous reservoir rocks, taking into account the wave-induced fluid flow between pores and fractures. This will be done by theoretical analysis based on the model of fractures as planes of discontinuity in porous rock, and on the theory of wave propagation in anisotropic porous media. The theoretic ....Theoretical and experimental study of elastic properties of porous media permeated by aligned fractures. The aim of the project is to develop a theoretical model for the elastic properties of fractured porous reservoir rocks, taking into account the wave-induced fluid flow between pores and fractures. This will be done by theoretical analysis based on the model of fractures as planes of discontinuity in porous rock, and on the theory of wave propagation in anisotropic porous media. The theoretical model will be verified using numerical simulations and ultrasonic measurements made on synthetic porous and fractured samples. The results are expected to benefit seismic exploration and the production of oil and gas in fractured reservoirs.Read moreRead less
