【 摘 要 】

The cryogenic thermal technique is used in this experimental study to provide a fundamental insight on the application of waterless fracturing techniques instead of water-based fracturing methods. The fracturing techniques in this study are captured applying axial and lateral strain gauges accompanied with Lab View software to record the crack initiation and propagation through conventional and unconventional synthetic rock samples. The experiments have been run under unconfined and confined pressure conditions. The investigations throughout of this laboratory study reveal the weakening of rock samples after being exposed to the cryogenic temperature. The experiments indicate a considerable reduction in the Young's Modulus and an increase in the Poisson's Ratio for rock samples exposed to the freezing temperature.
