3D measurements of hydrate surface area during hydrate dissociation in porous media using dynamic 3D imaging
Jarrar, Zaher A.; Alshibli, Khalid A.; Al-Raoush, Riyadh I.; Jung, Jongwon ( 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 ... -
3D synchrotron computed tomography study on the influence of fines on gas driven fractures in Sandy Sediments
Jarrar, Zaher A.; Al-Raoush, Riyadh I.; Hannun, Jamal A.; Alshibli, Khalid A.; Jung, Jongwon ( Elsevier , 2020 , Article)Production of methane from hydrate-bearing sediments requires hydrate dissociation for releasing mobile methane gas in sediments prior to gas production operations. Fines may migrate through or clog the pore space of ... -
Fines effect on gas flow in sandy sediments using μCT and pore networks
Hannun, Jamal A.; Al-Raoush, Riyadh I.; Jarrar, Zaher A.; Alshibli, Khalid A.; Jung, Jongwon ( Elsevier , 2022 , Article)Gas production from hydrate-bearing sediments requires methane dissociation, which induces two-phase gas flow, mobilizing fine clay particles from within saturated pores. Fines migration within sandy sediments results in ... -
Gas driven fracture during gas production using 3D synchrotron computed tomography
Jarrar, Zaher A.; Alshibli, Khalid A.; Al-Raoush, Riyadh I.; Jung, Jongwon ( Springer Verlag , 2019 , Conference Paper)During methane gas production from hydrate bearing sandy sediments, fine particles can migrate or clog the pores of sediments. Fines clogging induces a change in pressure gradient which affects the gas flow pattern and ... -
New model for estimating geometric tortuosity of variably saturated porous media using 3D synchrotron microcomputed tomography imaging
Jarrar, Zaher A.; Al-Raoush, Riyadh I.; Hannun, Jamal A.; Alshibli, Khalid A. ( John Wiley and Sons Inc , 2021 , Article)Tortuosity has a significantimpact on flow and transport characteristics of porous media and plays a major role in many applications such as enhanced oil recovery, contaminant transport in aquifers, and fuel cells. Most ... -
Three-Dimensional Evaluation of Sand Particle Fracture Using Discrete-Element Method and Synchrotron Microcomputed Tomography Images
Jarrar Zaher A.; Alshibli Khalid A.; Al-Raoush Riyadh I. ( American Society of Civil Engineers (ASCE) , 2020 , Article)Recent research showed that fracture of sand particles plays a significant role in determining the plastic bulk volumetric changes of granular materials under different loading conditions. One of the major tools used to ...
