The project seeks to improve our understanding of the mechanics and physics of hydraulic fracturing in unconventional shale/tight gas reservoirs. By determining key aspects of the mechanics and physics of hydraulic fractures in naturally fractured unconventional reservoirs the project aims to build an accurate continuum hydro-mechanical model for hydraulic fracturing stimulation. The new computational approach and software is expected to improve our fundamental understanding of the underlying physics of initiation and propagation of hydraulic fractures and their interactions with pre-existing natural faults. This has the potential to benefit the natural gas industry by providing information for better hydraulic fracture treatments and mitigation of the inherent risks of hydraulic fracturing and other processes.Read moreRead less
High-resolution optical studies of solids nucleation in cryogenic processes. During liquefied natural gas (LNG) production, low concentration impurities can freeze and block the cryogenic heat exchangers at the heart of the liquefaction process. Substantial knowledge gaps exist regarding the kinetics of these solids (i.e. the rate at which they form), especially at the part per million concentrations relevant to LNG. This project, in partnership with ExxonMobil Upstream Research Company, will us ....High-resolution optical studies of solids nucleation in cryogenic processes. During liquefied natural gas (LNG) production, low concentration impurities can freeze and block the cryogenic heat exchangers at the heart of the liquefaction process. Substantial knowledge gaps exist regarding the kinetics of these solids (i.e. the rate at which they form), especially at the part per million concentrations relevant to LNG. This project, in partnership with ExxonMobil Upstream Research Company, will use a proven high resolution optical technique to deliver new insight into solid nucleation and growth kinetics in the high-pressure cryogenic fluids that govern industrial blockage risk. The results will enable energy optimisation to increase liquefaction efficiency as well as tests of innovative blockage-remediation methods.Read moreRead less

This project aims to develop an efficient multi-scale modelling capability to quantify the effect of two-phase fluid flow within porous material by modelling rock wettability heterogeneity and alteration on two-phase flow performance for heterogeneous rock. Super-resolution methods combined with a deep learning approach will be used to determine a digital representation of reservoir rock, achieving an unprecedented combination of resolution necessary to resolve small-scale fluid connectivity and field of view required to capture heterogeneity. The project expects to develop a workflow to populate a high-resolution model with wettability parameters by combining micro-CT imaging with nuclear magnetic resonance measurements. This improved understanding should provide significant benefits by enhancing our capability to optimise enhanced oil and gas recovery programs.Read moreRead less
