Publication number: 20240003243Abstract: Methods, devices and systems are disclosed for magnetically ranging while drilling with a coiled tubing unit or drill pipe by way of a an electrically conducive but environmentally electrically insulated wire installed through a coiled tubing spool or drill pipe complete with electrically insulative subs in the coiled tubing bottom hole assembly or drill pipe. The method and systems allow for the injection of excitation current into the formation by way of selectively electrifying various drill stem components, thereby facilitating current collection on a target tubular which radially emanates a magnetic field about the target well tubular(s). The method and devices allow for the construction of complex downhole current injection configurations which allow for modification of the bottom hole assembly to maximize target well signal generation in the presence of adverse environmental conditions.Type: ApplicationFiled: August 28, 2023Publication date: January 4, 2024Applicant: Gunnar LLLPInventor: Clinton Moss
