Abstract
Systems and methods for active ranging-while-drilling (ARWD) for collision avoidance and/or well interception. A method for electromagnetic ranging of a target wellbore may comprise disposing a downhole measurement tool into a wellbore, wherein the downhole measurement tool may comprise receivers comprising at least one radially spaced pair of the receivers and at least one axially spaced pair of the receivers; performing field measurements with the receivers, where a first set of field measurements are from at least one radially spaced pair of the receivers, and a second set of field measurements are from at least one axially spaced pair of the receivers; and calculating at least one target well parameter of a target well from at least one of the first set of field measurements and the second set of field measurements.
