摘要

method for determining one or more parameters of a well bore formation, method for determining an electromagnetic coupling tensor of a well bore formation, and tool arranged in a well bore penetrating a formation a method for determining one or more parameters of a formation through a wellbore, at least a portion of the formation having substantially parallel contours, the method comprising arranging a tool in the wellbore, where the tool includes a transmitter having a bipolar moment in a angle theta t with respect to a longitudinal axis of the tool, and a receiver having a bipolar moment at a angle theta r with respect to the longitudinal axis of the tool, the transmitter and receiver comprising a transmitter / receiver pair; transmission of an electromagnetic signal during tool rotation; receiving the electromagnetic signal to produce a signal measured by the transmitter / receiver pair; and determining one or more formation parameters for the formation portion having substantially parallel contours based on the signal measured by the transmitter / receiver pair. a tool disposed in a well bore penetrating a formation, at least a portion of the formation having substantially parallel contours, the tool comprising a single transmitter having a bipolar transmitter moment at an angle theta t with respect to the longitudinal axis of the tool; a single receiver having a bipolar moment of receiver at an angle theta r to the longitudinal axis of the tool, and a rotary position indicator.
