However, in many instances (e.g., geothermal reservoirs and fault motion monitoring) the deformation mode is shear on natural fractures, but the resulting fiber signature has not been studied. In this work we use a 3D poroelastic hydraulic fracture model to obtain strain signatures...

... Abstract Distributed fiber optic strain measurements have become a widely used method for monitoring and diagnosing far-field strain induced during hydraulic fracturing. However, field observations have revealed that the mechanical decoupling between the fiber and the rock often happens...
