During numerical simulation, good convergence of numerical simulation results with experimental data was obtained, namely the temperature profile, cumulative gas production, and molar concentrations of gas components such as H 2 , CH4, CO and CO 2...

... Abstract Carbon Capture, Utilization and Storage (CCUS) processes are increasingly being utilized as a viable solution for carbon removal and meet the goal of net-zero carbon emissions by 2050. Captured carbon dioxide (CO 2 ) is stored deep underground – typically in depleted oil or gas (O...

... steam methane reforming (SMR), resulting in up to 10 kg of CO 2 emissions per 1 kg of H 2 . One potential approach for producing low-carbon hydrogen directly in hydrocarbon-rich reservoirs, leaving all greenhouse gases stored in the reservoir, is a novel hybrid catalytic-thermal process. In the current...

... emulsions. Our "heat+CO 2 " findings show that at 0.3 MPa, gaseous CO 2 tends to form bubbles, subsequently leaving an oil film after gas flooding. Contrastingly, after supercritical CO 2 flooding at 10 MPa, almost no oil film residues are found on the wall. At 20 MPa, CO 2 dissolution and extraction...

... Abstract Carbon dioxide (CO 2 ) injection for enhanced oil recovery (EOR), also known as CO 2 -EOR, has become increasingly important due to the growing need for CO 2 utilization and sequestration. CO 2 monitoring is an integral part of the CO 2- EOR process. Pulsed neutron (PN) well logging...

... Abstract The interfacial tension (IFT) of aqueous CO 2 systems plays a critical role in determining CO 2 capillary entry pressure, maximum CO 2 storage height, and subsurface storage capacity. Conventional methods for measuring IFT are time-consuming and resource-intensive. This study...

... Abstract Brine-gas interfacial tension ( γ ) is an important parameter to determine fluid dynamics, trapping and distributions at pore-scale, thus influencing gas (H 2 , CH 4 and CO 2 ) geo-storage (GGS) capacity and security at reservoir-scale. However, γ is a complex function of pressure...

... Abstract Foam flooding has been used to control gas mobility during oil displacement and CO 2 sequestration processes in subsurface porous media, mitigating the negative impacts of low gas viscosity, reservoir heterogeneity, and gravity override. In this research, we study the application...

... Abstract Carbon dioxide (CO 2 ) could be potentially stored in deep saline carbonate aquifers, taking advantage of its solubility in brine. Nevertheless, wormholes will be created due to the reactivity of carbonic acid with limestone. This research targets revealing the impact of live brine...
