Abstract
A geosignal is calculated based on a signal detected by a multicomponent resistivity tool () to facilitate determination of formation properties and infer location of the resistivity tool with respect to formation boundaries. The resistivity tool () detects an electromagnetic field response signal () at a series of azimuth angles () during one tool rotation. The signal measured at each azimuth angle is decoupled to obtain nonzero electromagnetic field tensor components for input into the geosignal calculation. The results of the geosignal calculation for at least a top bin (i.e., an azimuth angle of 360 degrees) and a bottom bin (i.e., an azimuth angle of 180 degrees) are evaluated to determine whether the tool () is near a formation boundary. If the tool is determined to be near a formation boundary, the resistivity of the layers of the formation on each side of the detected boundary can be inferred.
