Adhesive forces between two cleaved calcite surfaces in NaCl solutions: The importance of ionic strength and normal loading
(Journal article; Peer reviewed, 2018-12-15)The mechanical strength of calcite bearing rocks is influenced by pore fluid chemistry due to the variation in nano-scale surface forces acting at the grain contacts or close to the fracture tips. The adhesion of two ... -
Bulk moduli and seismic attenuation in partially saturated rocks: hysteresis of liquid bridges effect
(Journal article; Peer reviewed, 2019-03-20)A key task of exploration geophysics is to find relationships between seismic attributes (velocities and attenuation) and fluid properties (saturation and pore pressure). Experimental data suggests that at least three ... -
Estimation of Adsorption Capacity of CO2, CH4, and their Binary Mixtures in Quidam Shale using LSSVM: Application in CO2 Enhanced Shale Gas Recovery and CO2 Storage
(Journal article; Peer reviewed, 2020-02)Carbon dioxide enhanced shale gas recovery depends strongly on adsorption properties of carbon dioxide and methane. In this work, Least Squares Support Vector Machine (LSSVM) optimized by Particle Swarm Optimization, has ... -
Investigation of a new application for cellulose nanocrystals: a study of the enhanced oil recovery potential by use of a green additive
(Journal article; Peer reviewed, 2018-02)Cellulose nanocrystals (CNC) were investigated for use in a potential new application, enhanced oil recovery. Core flooding experiments were performed on outcrop sandstone cores using CNC particles dispersed in low salinity ... -
Steady State Relative Permeability Experiments with Capillary End Effects: Analytical Solutions including Derivation of the Intercept Method
(Journal article; Peer reviewed, 2020-09)Steady state relative permeability experiments are performed by coinjection of two (or more) immiscible fluids. The relative permeabilities can be calculated directly from the stabilized pressure drop and saturation of the ...
