Although hydraulic fracturing has been widely used for decades, and the technology to implement and interpret the induced fractures has been continuously evolving, many aspects are still not understood. Specifically, this includes hydraulic fracture initiation and propagation mechanisms and the effect of stress state and rock fabric. The objective of this study was to determine the differences between hydraulic fracturing under isotropic and anisotropic stress conditions.
