Abstract: In some embodiments, a magnetometer mounting apparatus and system may reduce noise and magnetic flux interference by mounting the magnetometer inside a cavity in a collar that fits around a tool insert. The cavity may be sealed with a hatch cover/outsert. Another embodiment mounts a plurality of magnetometers around the periphery of a mounting ring that is coupled to the insert. Yet another embodiment mounts the magnetometers in a gap sub in the BHA. Still another embodiment longitudinally mounts the magnetometers on the insert such that a diagonal distance between two magnetometers is the greatest possible on the insert.

Abstract: A magnetic flux receiver assembly includes a collar that defines a central passageway and an axial collar face, and a tool insert disposable within the central passageway and defining an axial insert face. One or more magnetometers are operatively coupled to the tool insert. One or more buttons are coupled to one or both of the axial collar face and the axial insert face such that an axial gap is defined at an axial interface between the axial collar face and the axial insert face to prevent electrical communication across the axial interface.

Abstract: A tubular string includes a first tubular member with a pin end with pin threads and a pin external load shoulder. The tubular string also includes a second tubular member with a box end with a box external load shoulder and box threads, the pin threads being threadable into the box threads to form a connection, wherein the pin external load shoulder has an outer diameter (OD) that is different than an OD of the box external load shoulder. A load distribution sleeve is locatable between the first and second tubular members when threaded together and includes a first end facing the first tubular member and a second end facing the second tubular member, wherein the ODs of the load distribution sleeve first and second ends match the ODs of the pin and box external load shoulders respectively. The load distribution sleeve contacts the pin and box external load shoulders and distributes a make-up load between the pin and box external load shoulders when the connection is made up.

Abstract: Apparatus, systems, and methods may operate to couple a power supply to a ground point associated with a well, and to a lower portion of a conductive casing disposed within the well, where the lower portion of the conductive casing is separated by an insulating gap from an upper portion of the conductive casing, the upper portion of the conductive casing being at a higher elevation of the first well than the lower portion of the conductive casing. Further activity may include injecting an excitation signal into the lower portion of the conductive casing to induce a magnetic field in a geological formation surrounding the first well. Additional apparatus, systems, and methods are disclosed.

Abstract: Logging downhole exposes components of logging tools, for example, antennas to abrasive and erosive operating conditions. A protective sleeve may disposed about an antenna assembly to protect the antenna assembly for the downhole operating conditions. To permit transmission and receipt of signals by and too the antenna assembly, slots are formed or disposed in the protective sleeve. A non-conductive composite insert is formed in the slots to protect the internal components of the protective sleeve, for example, the antenna assembly, from the operation conditions. A non-conductive composite inner liner is formed in an annulus of the protective sleeve and adheres to the protective sleeve and the non-conductive composite insert. The non-conductive component insert and inner liner allow signals to be transmitted and received by the antenna assembly so that logging operations can be completed without undue delay and the expense of repairing or replacing worn or damaged components.
