3D measurements of hydrate surface area during hydrate dissociation in porous media using dynamic 3D imaging
( Elsevier , 2020 , Article)A better understanding of the kinetics of hydrate dissociation is essential to reliably predict gas production potential from natural hydrate reservoirs. Most hydrate dissociation models assume hydrates to be a constant ... -
Dynamic 3D imaging of gas hydrate kinetics using synchrotron computed tomography
( EDP Sciences , 2020 , Conference Paper)The availability of natural gas hydrates and the continuing increase in energy demand, motivated researchers to consider gas hydrates as a future source of energy. Fundamental understanding of hydrate dissociation kinetics ... -
Dynamic Imaging of Hydrate Specific Area Evolution during Xenon Hydrate Formation
( Qatar Univesrity Press , 2020 , Conference Paper)Gas hydrates are ice-like structures formed under high pressure and low temperature conditions. They are considered as a potential energy source due to their abundance and the increase in energy demand worldwide. A fundamental ... -
Effects of CH4-CO2 replacement in hydrate-bearing sediments on S-wave velocity and electrical resistivity
( Elsevier , 2020 , Article)CH4-CO2 replacement has been considered as a method for methane production from hydrate-bearing sediments to maintain sediment stability. Sediment stability has been studied at both the particle scale and mesoscale. However, ... -

( Elsevier , 2021 , Article)CH4-CO2 replacement method has the advantages of sequestering carbon dioxide and sediment stability compared to other methods such as depressurization and thermal stimulation. However, the production efficiency using CH4-CO2 ... -
Hydrate surface area measurements during dissociation using dynamic 3d synchrotron computed tomography
( European Association of Geoscientists and Engineers, EAGE , 2019 , Conference Paper)Availability of natural hydrates and ongoing rise in demand for energy, motivated researchers to consider hydrates as a potential energy source. Prior to gas production operations from hydrate-bearing sediments, hydrate ... -
Pore networks to characterize formation damage due to fines at varied confinement and sand shape
( European Association of Geoscientists and Engineers, EAGE , 2019 , Conference Paper)Carbon sequestration in geological formations is in demand for many applications, especially energy production from hydrates. During gas production in a sandy hydrate reservoir, two phase flow and changes in confinement ... -
Pore-scale mechanisms associated with permeability impairment in porous media: A micromodel study
( European Association of Geoscientists and Engineers, EAGE , 2019 , Conference Paper)Recently, researchers are attracted towards the gas production from hydrate bearing sediments considering its abundance in marine continental margins and persisting demand for alternate energy. Dissociation of hydrate into ...
