    Abstract: A downhole probe of a drilling rig has a probe sleeve for protecting the downhole probe. The probe sleeve may be made of a metal or a polymer such as polyphenylene sulfide. The probe sleeve may be heat-shrinkable to provide a tight fit between the downhole probe and the probe sleeve. The probe sleeve may include one or more protrusions shaped to engage a centralizer surrounding at least part of the downhole probe. The one or more protrusions may be arranged to prevent rotation of the centralizer relative to the probe sleeve. The probe sleeve may be made using a modified extrusion process and may include reinforcement to add strength to weld-lines along the length of the probe sleeve. The protrusions may also be used as reinforcement.

    Abstract: An assembly for use in subsurface drilling includes a downhole probe supported in a drill string section by centralizing features of a centralizer that is slidably removable from the drill string section. The centralizer may comprise a tubular body having a bore defined through it. A bore wall of the centralizer is fluted to provide inward contact points that support the downhole probe. The downhole probe may be supported for substantially its entire length. The centralizer may optionally comprise and/or be coated with a vibration damping and/or electrically insulating material.

    Abstract: A jig and method useful for coupling and/or uncoupling drill string sections. In some embodiments, the jig comprises a body having an outer surface for engaging a torqueing tool and a cavity extending from a first end to a second end of the body and an engagement means at the first end of the body. The engagement means may be dimensioned to non-rotationally engage an outer surface of a first end of a drill string section and the cavity may be sized to fit about a drill string section.

    Abstract: An electromagnetic telemetry signal generating assembly comprises a first section of drill string, a second section of drill string, a gap sub configured to insulate the first section from the second section, and a power source configured to provide a first voltage to a control circuit. The control circuit is configured to drive a second voltage between the sections of drill string. The gap sub provides a gap of at least 12 inches (30 cm). The second voltage may be different than the first voltage.
