... (TSO) fracture geometry. Two-dimensional analysis or even more sophisticated computer simulations typically only model the fracture process up to the onset of TSO, and do not calculate the fracture geometry beyond the onset of TSO. This paper presents results of three-dimensional hydraulic fracturing...

The polyaxial test parameters were determined through pre-test numerical modeling where the intention was to design stress paths that simulated near-wellbore stress conditions. Subsequently the results...
