Densities for Ternary System of CaCl2–H2O–CO2 at Elevated P-T: An Experimental and Modeling Approach

Bastami, Alireza; Pourafshary, Peyman; Shafiei, Ali (Energies, 2018-10-20)

Very few thermodynamic models exist for estimation of density alteration due to solution of CO2 in a pure H2O and CaCl2–H2O system. All of these models require density of CaCl2 solution to estimate density of CaCl2–H2O–CO2 ...

PROPAGATION OF CRYOGENIC THERMAL FRACTURES FROM UNCONFINED PMMA BOREHOLES

Cha, Minsu; Alqahtani, Naif B.; Yin, Xiaolong; Wang, Lei; Yao, Bowen; Kneafsey, Timothy J.; Miskimins, Jennifer L.; Wu, Yu-Shu (MDPI, 2021-09-01)

In cryogenic fracturing, a rock surface exposed to cryogenic fluids undergoes a large thermal gradient, and the resultant local tensile stress overcomes rock strength and initiates fractures. This study investigates the ...
