APPARATUS AND METHODS FOR GEOSTEERING

摘要

Various embodiments include apparatus and methods to generate geosignal responses. Geosignal responses may be generated that include a representation of a determination of variation between a XX coupling component and a YY coupling component from acquired signals. Such geosignals may be used to 5 address a blindspot problem suffered in conventional geosteering in a drilling condition where the logging tool is located at layered formations with symmetric resistivity profiles. Additional apparatus, systems, and methods are disclosed.
