Journal ArticleDOI
Physical and structural changes in shale associated with supercritical CO2 exposure
TL;DR: In this article, the physical and structural changes in shale after 30 days of ScCO 2 exposure (T ǫ = 40°C, Pǫ= 16 MPa) were studied.
Journal ArticleDOI
Adsorption Equilibrium of CO2 and CH4 and Their Mixture on Sichuan Basin Shale
TL;DR: In this article, the adsorption selectivity factors for CO2 over CH4 (αCO2/CH4) and thermodynamic parameters were estimated using the virial model and the Brunauer-Emmett-Teller model.
Journal ArticleDOI
Experimental study of the effects of sub- and super-critical CO2 saturation on the mechanical characteristics of organic-rich shales
TL;DR: In this article, the effects of sub-critical CO2 (SubCO2) and super critical CO2 saturation on shale mechanics were investigated at 38°C on shale samples from the Sichuan Basin.
Journal ArticleDOI
Supercritical carbon dioxide fracturing in shale and the coupled effects on the permeability of fractured shale: An experimental study
TL;DR: In this article, the effectiveness of supercritical carbon dioxide (ScCO2)-based reservoir fracturing associated with CO2enhanced shale gas recovery is explored to reduce water utilization in shale gas production and has the potential for CO2 sequestration.
Journal ArticleDOI
Measurements and modelling of CH4 and CO2 adsorption behaviors on shales: Implication for CO2 enhanced shale gas recovery
TL;DR: In this paper, the results of an adsorption study of CH4 and CO2, in single gas environment, on a set of shale samples taken from the Sichuan and Ordos Basins.
