Abstract: The present disclosure relates to a method and system for characterization of torque and torsional vibration in rotating bodies. More specifically, the present disclosure describes high-fidelity, high-speed characterization of the rotary motion of a body without the requirement for surface modification. The method and system rely on the inherent properties of the surface of the rotating body to determine the degree to which the rotating body vibrates, twists, or is otherwise translated.

Abstract: An optical fiber seal includes: an annular layer bonded to and in contact with an outer glass layer of a length of an optical fiber; and a glass sealing layer bonded to an outer surface of the annular layer and configured to withstand conditions in a downhole environment, the glass sealing layer configured to hermetically seal the length of the optical fiber.

Abstract: Systems, program product, and methods for monitoring linearity of a down-hole pumping system assembly during deployment within a bore of a casing of a well positioned to extract hydrocarbons from a subterranean reservoir and selecting an optimal operational position for the down-hole pumping system assembly within the bore of the casing, are provided. Various embodiments of the systems allow an operator to ensure that a motor and pump of a down-hole pumping system assembly are installed in an optimal position in a well by ensuring alignment across the pump stages casing and motor casing. The system includes a groove extending along an outer surface of a housing of the pumping system assembly, and an optical sensing fiber mounted in the groove.

Abstract: A sensing assembly including a fiber for monitoring at least one condition or parameter and a strip formed from a pair of laminae disposed with the fiber. The laminae are arranged parallel to each other and engaged longitudinally along the fiber for enabling the strip to secure the fiber in place. A method of monitoring a parameter or condition with a sensing assembly is also included.
