Quantifying morphology of sands using 3D imaging
(
American Society of Civil Engineers (ASCE)
, 2015 , Article)
Particle morphology plays a significant role in influencing engineering behavior of granular materials. Surface texture, roundness, and sphericity represent distinct multiscale measures needed to fully describe particle ...
3D synchrotron computed tomography study on the influence of fines on gas driven fractures in Sandy Sediments
(
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 ...
Discrepancy in the Critical State Void Ratio of Poorly Graded Sand due to Shear Strain Localization
(
American Society of Civil Engineers (ASCE)
, 2020 , Article)
The critical state (CS) concept is a theoretical framework that models the constitutive behavior of soils, including sand and other granular materials. It supports the notion of a unique postfailure state, where the soil ...
Fines effect on gas flow in sandy sediments using μCT and pore networks
(
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 ...
New model for estimating geometric tortuosity of variably saturated porous media using 3D synchrotron microcomputed tomography imaging
(
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 ...
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 ...
Three-Dimensional Evaluation of Sand Particle Fracture Using Discrete-Element Method and Synchrotron Microcomputed Tomography Images
(
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 ...
