Autor: Hemant Sharma, Wadi H. Imseeh, Khalid A. Alshibli, Amirsalar Moslehy, Timothy J. Truster, Zaher A. Jarrar, Peter Kenesei

Publikováno v: Journal of Applied Crystallography. 54:1379-1393

Rock salt caverns have been extensively used as reliable repositories for hazardous waste such as nuclear waste, oil or compressed gases. Undisturbed rock salt deposits in nature are usually impermeable and have very low porosity. However, rock salt

Fines effect on gas flow in sandy sediments using μCT and pore networks

Autor: Jamal A. Hannun, Riyadh I. Al-Raoush, Zaher A. Jarrar, Khalid A. Alshibli, Jongwon Jung

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 subsequent pore clogging, red

Influence of Sand Morphology on Interparticle Force and Stress Transmission Using Three-Dimensional Discrete- and Finite-Element Methods

Autor: Khalid A. Alshibli, Wadi H. Imseeh, Zaher A. Jarrar

Publikováno v: Journal of Engineering Mechanics. 147

In the last two decades, particle morphology has emerged as an essential and critical property for proper evaluation of the constitutive behavior of granular materials. When a mass of sand ...

Three-Dimensional Evaluation of Sand Particle Fracture Using Discrete-Element Method and Synchrotron Microcomputed Tomography Images

Autor: Khalid A. Alshibli, Zaher A. Jarrar, Riyadh I. Al-Raoush

Publikováno v: Journal of Geotechnical and Geoenvironmental Engineering. 146

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 better understand the influenc

3D synchrotron computed tomography study on the influence of fines on gas driven fractures in Sandy Sediments

Autor: Jongwon Jung, Riyadh I. Al-Raoush, Khalid A. Alshibli, Zaher A. Jarrar, Jamal Hannun

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 sandy sediments depending on the

Publikováno v: Scopus-Elsevier

Methane hydrates are promising unconventional energy source with natural reserves above 1,000 Trillion m3. Hydrates are found in saturated sandy sediments, where multi-phase flow of gas takes place through sediment's pores, physical phenomenon at por

Hydrate surface area measurements during dissociation using dynamic 3d synchrotron computed tomography

Autor: Jamal Hannun, Zaher A. Jarrar, Khalid A. Alshibli, J. Jung, Riyadh I. Al-Raoush

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 dissociation is required to re

Pore networks to characterize formation damage due to fines at varied confinement and sand shape

Autor: Jamal Hannun, J. Jung, Khalid A. Alshibli, Riyadh I. Al-Raoush, Zaher A. Jarrar

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 takes place. Nine fully satura
