Unconventional and conventional reservoirs provide opportunities for beneficial use such as enhanced recovery, supercritical CO2 fracturing, and storage of gases such as CO2 and ancillary gases, or potentially hydrogen. The purpose of this study is to use Australian examples of unconventional rock packages to understand the controls on CO2 reactivity and mineral trapping (the most secure form of storage) and to demonstrate if there is potential for storage in unconventional reservoirs. Characterization of core from the Surat, Eromanga, and Cooper basins, is used to populate geochemical models and compare the potential for mineral trapping of CO2. Interburden from a coal seam gas reservoir ranged from clay rich mudstones to interlaminated and calcite cemented sandstones. The interburden samples contained high plagioclase and chlorite mineral content and these were predicted in geochemical dissolved CO2-production water-rock reactivity models to alter to calcite, ankerite, siderite and dawsonite mineral trapping 4 - 12 kg CO2 per m3. CO2 mineral trapping as siderite and ankerite in quartz rich oil sandstone was predicted to be lower than in interburden. Gas shale samples and black oil shales also contained a high mica, chlorite and feldspar content that can be converted to carbonate minerals, mineral trapping CO2. Unconventional rock packages have strong potential for mineral trapping during CO2 storage. In future a combination of characterization, CO2 experiments and models should be performed for reservoirs and seals from sites of interest to understand initial changes to poro-perm. Several sandstones characterized here showed indicators of natural CO2 or acidic fluid alteration with carbonates and clays filling natural fractures. Characterizing regions, where gases have been stored naturally and carbonates precipitated are valuable to validate long term predictions. Understanding the CO2 storage potential of different reservoirs will also have applicability to future hydrogen storage.]]> Tue 14 Nov 2023 14:51:44 AEDT ]]> Salt effects on the dilational viscoelasticity of surfactant adsorption layers https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:46745 Tue 09 Jan 2024 13:35:13 AEDT ]]> Effect of mono- and di-valent cations on PFAS removal from water using foam fractionation – A modelling and experimental study https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47979 Na+ > K+. It was also observed that at salt concentrations above 100 mM for Na+, above 10 mM for K+ and Mg2+ but between 0.1 and 10 mM for Ca2+ in the presence of greater than 4 ppm of SDS, the cations can complex with the SDS in the system and suppress foam formation due to the surfactant precipitation. Foam fractionation was able to remove perfluorohexane sulphonic acid (PFHxS), perfluorooctanoic acid (PFOA) and perfluorooctane sulphonic acid (PFOS) from a sample of Australian groundwater to below the analytical detection limit of 0.1 ppb within 60 min with SDS being used as the co-foaming agent, but was unable to remove the short chain perfluorobutanoic acid (PFBA).]]> Tue 02 Jul 2024 14:29:32 AEST ]]> Effect of selected monovalent salts on surfactant stabilized foams https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:48681 Thu 17 Aug 2023 12:52:29 AEST ]]> A machine learning-based predictive model for real-time monitoring of flowing bottom-hole pressure of gas wells https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:48247 Sat 11 Mar 2023 12:50:53 AEDT ]]> Sustainable dewatering of unconventional gas wells using engineered multiphase flow dynamics https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:41882 Mon 19 Jun 2023 14:37:34 AEST ]]> Effect of divalent and monovalent salts on interfacial dilational rheology of Sodium dodecylbenzene sulfonate solutions https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:41875 MgCl2 > KCl > NaCl > LiCl.
