Abstract: There is provided a gap sub-assembly for electrically isolating an upstream portion of a drill string from a downstream portion of the drill string. The gap sub-assembly includes a first sub; a second sub; and a non-conductive isolation between the first sub and the second sub, the non-conductive isolation being interposed between respective shoulders of the first sub and the second sub and being interposed between respective threads of a male end of the first sub and a female end of the second sub, the non-conductive isolation comprising an insulative wrapping between at least the respective threads of the first and second subs, wherein connecting the female end of the second sub to the male end of the first sub over the insulative wrapping electrically isolates the respective threads of the first and second subs. A method for assembling such a gap sub-assembly is also provided.

Abstract: A system and method are provided for providing electromagnetic (EM) measurement-while-drilling (MWD) telemetry capabilities using an existing mud-pulse MWD tool. An EM tool intercepts the output from the mud-pulse tool and generates an EM signal that mimics a mud-pulse pressure signal. The EM signal is intercepted at the surface by a receiver module that conditions the signal and inputs the signal into the existing pulse tool receiver. Since the EM signal mimics a mud-pulse signal, the pulse tool receiver does not require software or hardware modifications in order to process an EM telemetry mode. The EM tool can be adapted to also provide dual telemetry by incorporating a conventional pressure pulser that would normally be used with the pulse tool.

Abstract: A device measures the operating angle of a universal joint in a drive train system without any physical contact with the components of the drive train system. The drive train system can include first and second shafts that are connected together by the universal joint. The device includes a first sensor for generating a first signal that is representative of the angular orientation of the first shaft relative to the horizontal and a second sensor for generating a second signal that is representative of the angular orientation of the second shaft relative to the horizontal. Each of the first and second sensors can include a pair of non-contact sensors, such as a pair of laser distance sensors, that are mounted on a base. A controller is responsive to the first and second signals for determining the operating angle of the universal joint.

Abstract: A fixture for supporting a sensing device on a variety of differently sized and shaped articles and for protectively enclosing such a sensing device when the article is moved during use includes a base including a pair of spaced apart feet that engage the outer surface of the article. The feet defined a recessed area in the bottom surface of the base that can receive portions of the article therein regardless of the radius of curvature or other shape thereof. An enclosure area is provided in the base that can receive a sensing device therein. A lid cooperates with the base to provide a protective enclosure for the enclosed area and the sensing device disposed therein. The lid can be retained on the base by any desired retaining structure. A seal can be provided between the lid and the base to prevent dirt, water, and other contaminants from entering into the enclosed area when the lid cooperates with the base.
