APPARATUS AND METHOD USING MEASUREMENTS TAKEN WHILE DRILLING TO GENERATE AND MAP MECHANICAL BOUNDARIES AND MECHANICAL ROCK PROPERTIES ALONG A BOREHOLE

摘要

The present disclosure involves a novel 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 drilling fluid system, to identify the nature and occurrence of fractures, fracture swarms and other mechanical discontinuities (boundaries) such as bedding planes and/or faults that offset or otherwise separate rock formations with different mechanical rock properties.
