ABSTRACT:
A method is disclosed for determining a direction of a target formation with respect to an instrument in a wellbore. The target has an electrical conductivity different than earth formations surrounding the wellbore. The method includes inducing time varying electromagnetic fields in the formations surrounding the wellbore. The electromagnetic fields have at least some components along mutually orthogonal directions. Voltages induced by the time varying electromagnetic fields are detected. The detecting is performed to have at least some component along mutually orthogonal directions. The direction of the target is calculated from the detected voltages.
