Title: OPTIMIZATION OF RANGING MEASUREMENTS
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 include disposing an electromagnetic ranging tool in a wellbore, wherein the electromagnetic ranging tool comprises an electromagnetic transmitter and an electromagnetic receiver; exciting a subterranean formation with the electromagnetic transmitter; adjusting at least one orientation of the electromagnetic transmitter, the electromagnetic receiver, or both the electromagnetic transmitter and the electromagnetic receiver; exciting the target wellbore with the electromagnetic transmitter; measuring at least one component of an electromagnetic signal from the target wellbore with the electromagnetic receiver; and determining at least one ranging parameter of the target wellbore based, at least in part, on the at least one component of the electromagnetic field measured by the electromagnetic receiver.
