APPARATUS AND METHOD OF USING MEASUREMENT WHILE DRILLING DATA TO GENERATE MECHANICAL ROCK-STRENGTH PROPERTIES AND MAP MECHANICAL ROCK-STRENGTH PROPERTIES ALONG A BOREHOLE

摘要

The present disclosure involves a obtaining force and motion data from a measurement while drilling apparatus or the like having sensors measuring forces and motions of the drill bit while drilling a well. The force and motion data is transformed into spectral pairings from which distributions, such as force displacement and power law relationship, are generated. From the distributions various rock strength properties along the well bore may be derived and used in various possible completion processes such as perforation placements and packer placements.
