Abstract
Systems and methods for well-drilling operations involving magnetic ranging with a rotating magnetic dipole are provided. In one embodiment, a system for determining a relative location of a magnetic dipole includes a three-axis magnetometer configured to obtain measurements of a time-dependent magnetic field caused by the magnetic source rotating about an axis and data processing circuitry configured to determine a transverse angle of rotation of the measurements such that one of two transverse components is in phase with one axial component when the transverse angle of rotation is used to transform the measurements. The data processing circuitry may determine a spatial relationship between the magnetic source and the three-axis magnetometer based at least in part on the transverse angle of rotation.
