Abstract

A method of determining the orientation of an electric and magnetic receiver deployed remotely which comprises: measuring electric and magnetic data in response to an applied active source; resolving the data into components in-line (x-component) to the electric dipole of the receiver and orthogonal to this (y- component); the data is transformed from the time domain to the frequency domain and normalised; and the rotation angle ϑ between the direction of the source dipole and the receiver dipole is calculated.
