An Evaluation Method of Brittleness Characteristics of Shale Based on the Unloading Experiment
Shale reservoir has an initial unloading effect during the natural uplift and erosion process, which causes the shale brittleness to change, affecting the design of the fracturing scheme. To consider this, the axial compression loading and confining pressure unloading experiment of shale is carried...
