Abstract

See full text

Tools, systems and methods for fast formation dip angle estimation, at least some of which include a logging tool that includes at least one transmit antenna, at least one receive antenna and a controller. The controller measures coupling parameters between the transmit and receive antennas, with at least one of the coupling parameters being measured as a function of depth and azimuthal angle. The controller further determines if a surrounding formation is anisotropic and heterogeneous based at least in part on at least one of the coupling parameters, and if so, derives a dip angle from a partial derivative with respect to depth and artificial dip angle of the coupling parameter(s).
