Abstract:
A steering tool is movable by a drill string to form an underground bore along an intended path. A sensing arrangement of the steering tool detects its pitch and yaw orientations at a series of spaced apart positions along the bore, each position is characterized by a measured extension of the drill string. The steering tool further includes a receiver. At least one marker is positioned proximate to the intended path, for transmitting a rotating dipole field to expose a portion of the intended path to the field for reception by the receiver. The detected pitch orientation, the detected yaw orientation and the measured extension of the drill string are used in conjunction with magnetic information from the receiver to locate the steering tool. The steering tool may automatically use the magnetic information when it is available. A customized overall position determination accuracy can be provided along the intended path.

Claim (Index 1):
A steering tool that is moved by a drill string in a system and steered to form an underground bore along an intended path, said steering tool comprising:\n a triaxial accelerometer for sensing an orientation of the steering tool at each of a series of positions of the steering tool along said underground bore, each of which positions is characterized by a measured extension of said drill string such that the sensed orientation and the measured extension of the drill string are each subject to a measurement error; a receiver configured for receiving a rotating dipole field to produce magnetic information from at least one marker positioned proximate to the intended path which marker transmits a rotating dipole field such that at least a portion of the intended path is exposed to the rotating dipole field; and a processing arrangement that is configured to determine one or more positions of the steering tool, along one portion of the intended path that is not exposed to the rotating dipole field, with a given accuracy by numerical integration of the sensed orientation based on the measured extension of the drill string, and to determine one or more positions of the steering tool along another portion of the intended path, that is exposed to the rotating dipole field, with an enhanced accuracy, by said numerical integration in conjunction with the magnetic information to compensate for the accumulation of the measurement error along the unexposed portion of the intended path such that the enhanced accuracy is greater than the given accuracy.
