Applications of Micro-Indentation Technology to Estimate Fracture Toughness of Shale

Applications of Micro-Indentation Technology to Estimate Fracture Toughness of Shale

The fracture toughness of shale is a basic parameter that can provide effective theoretical support for wellbore stability and hydraulic fracturing of a shale reservoir. Due to the composition and microstructure, there are many problems in evaluating the mechanical properties of shale in a macroscop...
