RANGING USING CURRENT PROFILING

摘要

Systems and methods provide a mechanism to provide enhanced features for well ranging. Various embodiments may include generating a current profile for a target well, acquiring magnetic signals at a second well, and determining ranging to the target well with respect to the second well using the magnetic signals and the current profile. Additional apparatus, systems, and methods are disclosed.
