methods for characterization of rock properties and for hydraulic fracturing.

摘要

The present description relates to a new way of using drilling vibrations generated by the deformation of a rock formation in response to forces acting on the rock formation, where the forces are related to a drill bit and / or fluid system. drilling, to identify the nature and occurrence of fractures, fracture paths and other mechanical discontinuities (boundaries) such as foundation planes and / or faults that deviate or otherwise separate rock formations with different mechanical rock properties.
