摘要： ABSTRACT OF THE DISCLOSURE
The disclosure is directed to a method, system, and apparatus that can be utilized to provide electrical power to an active magnetic ranging (AMR) bottom hole assembly (BHA). The electrical power can be transmitted through a drill string, with an end attached drilling BHA, inserted into a wellbore. The AMR BHA can include a powered isolation sub to create an isolated electrical zone along the drill string. The AMR BHA can create an electrical short along a designated portion of a formation to create a resultant magnetic field to be detected by the AMR BHA or other downhole tools. A drilling wellbore can maintain drilling operations while actively ranging a target well for intercept and other operations. The drilling BHA does not need to be removed from the wellbore to enable the activities of the AMR BHA, and access to the target wellbore is not needed.

摘要： A ranging system having magnets positioned at various locations along the drive system. Location of the magnetics is shifted to different points on the drilling string to remove the need for a nearby bit sub that would detrimentally affect the steerability of the drilling system.

摘要： A method for estimating a property of an earth formation penetrated by a borehole, the method comprising generating a first transient electromagnetic fields with a transmitter on a carrier located outside of the borehole and receiving associated signals, calculating a bucking coefficient using the measured signals, conveying the carrier through a borehole, generating a second transient electromagnetic field and receiving associated signals, calculating, a bucked signal using the bucking coefficient and the downhole signals, calculating synthetic formation signals, calculating synthetic formations signals by applying a Duhamel's integral to the measured signals and the synthetic formation signals, calculating a synthetic bucked signal, and performing an inversion of a formation model to estimate a property of the formation such that an inverted synthetic bucked signal and an inverted bucked signal coincide within a predetermined range.
