Processing is performed by rotating the drill guide and geological

Various embodiments and comprises processing means and a method of geosteering with respect to logging. The method and apparatus further comprises a signal acquisition due to operation of the rotary drilling tool in the borehole of the well generated, wherein the drill comprises a longitudinal axis inclined with respect to the receiver antenna of the drill, and the two transmitter antennas. It may be the rotational direction of the drill to process the acquired signal to determine characteristics of the formation associated with and / or signals for geological drilling operations geosteering.
