Abstract:
1. A method of conducting logging operations in a borehole penetrating an earth formation, comprising: compensating for effects of misalignment between at least one oriented transmitter on a bottom hole assembly (BHA) and at least one oriented receiver on the BHA on signals generated by the at least one oriented receiver using an inversion on at least one measurement from the signals generated by the at least one oriented receiver in response to energy generated by the at least one oriented transmitter; and estimating at least one parameter of interest of the earth formation using the signals generated by the at least one oriented receiver after compensation for effects of misalignment, wherein the at least one oriented receiver includes one of: i) a single oriented receiver and ii) a plurality of non-collocated oriented receivers, and wherein the at least one oriented transmitter includes one of: i) a single oriented transmitter and ii) a plurality of non-collocated oriented transmitters.
