    Abstract
    Cryogenic fracturing is a new fracturing concept that uses cryogenic fluids as fracturing fluids. Its mechanism rests on the effect of a thermal shock introduced by cryogen on the hot surface of reservoir rock. The thermo-mechanical properties of rock and failure criteria play very important roles during the cryogenic fracturing process. The objective of this research is to conduct cryogenic fracturing experiments on concrete and rock samples and build a simulation tool. For the experimental aspect, a tri-axial stress confining system with capability of injecting liquid nitrogen or other cryogenic ...
