摘要

method of guiding well drilling operation using acoustic measurements, system for guiding well drilling operation using rock stress measurements, and computer readable storing instructions for guiding a well drilling operation using acoustic measurements. a method of guiding a well drilling operation using acoustic measurements. the method includes obtaining, using a central processing unit (cpu), a clean wet matrix line for the well, where the clean wet matrix line includes numerous normal compression values, obtaining, using the cpu, acoustic measurements of at least one profiling tool during drilling at a current depth of the drilling operation, where the acoustic measurements include a compression to shear rate ratio and a delta-t compression measurement, and determine, using cpu, a current phase drilling operation by comparing acoustic measurements to the clean wet matrix line. The method further includes, in response to the determination that the current phase is not a target phase, generate an updated well path to guide the drilling operation toward the target phase and adjust the drilling operation using the well path. updated.
