ABSTRACT:
Various systems and methods determine a distance, magnitude, and azimuthal angle describing the location of an anomaly within a geologic formation. For example, a method involves identifying an electrical characteristic (e.g., resistivity or conductivity) at each of several sensors in a measurement-while-drilling (MWD) tool. Based on the electrical characteristic, information identifying a formation property of the anomaly is generated. The information includes at least one magnitude and at least one distance. Information information identifying an azimuthal angle is also generated based upon the electrical characteristic. The azimuthal angle relates a position of the anomalous formation to a position of a first sensor in the MWD tool.
