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 ... -
Dynamic 3D imaging of gas hydrate kinetics using synchrotron computed tomography
Jarrar, Zaher; Al-Raoush, Riyadh; Alshibli, Khalid; Jung, Jongwon ( 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 ... -
Effects of CH4-CO2 replacement in hydrate-bearing sediments on S-wave velocity and electrical resistivity
Jung, Jongwon; Ryou, Jae Eun; Al-Raoush, Riyadh I.; Alshibli, Khalid; Lee, Joo Yong ( 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, ... -
Effects of Fine-Grained Particles' Migration and Clogging in Porous Media on Gas Production from Hydrate-Bearing Sediments
Jung, Jongwon; Kang, Hongsig; Cao, Shuang Cindy; Al-Raoush, Riyadh I.; Alshibli, Khalid; Lee, Joo Yong... more authors ... less authors ( Hindawi Limited , 2019 , Article)The migration of fine particles in porous media has been studied for different applications, including gas production from hydrate-bearing sediments. The clogging behavior of fine particles is affected by fine particle-pore ... -
Effects of soaking process on CH4-CO2 replacement efficiency for hydrate-bearing sediments
Ryou, Jae Eun; Al-Raoush, Riyadh I.; Alshibli, Khalid; Lee, Joo Yong; Jung, Jongwon ( 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 ... -
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 ... -
Gas Driven Fracture during Gas Production using HeleShaw Cell
Al-Raoush, Riyadh; Jarrar, Zaher; Alshibli, Khalid; Jung, Jongwon ( Hamad bin Khalifa University Press (HBKU Press) , 2018 , Conference Paper)Methane hydrate is considered a potential energy source, with worldwide reserves on the order of 500-10,000 Gt of carbon. The production of Methane from hydratebearing sediments requires hydrate dissociation for releasing ... -
Impact of fines type on gas flow using 3D micro-computed tomography
