Abstract: A system for positioning a sensor within a flow path of a wellbore annulus includes a work string extending into the wellbore annulus from a surface location. The system includes a movable arm on the work string, the arm transitioning between a first radial location and a second radial location. The system further includes a bracket coupled to the arm, the bracket being pivotable about a pivot axis, wherein the bracket supports the sensor and transitions the sensor from a stored position to a deployed position.

Abstract: A sensor deployment system includes a first bulkhead arranged at a first end of a downhole tool, a second bulkhead arranged at a second end of the downhole tool, opposite the first end, a first pivot block arranged proximate the first bulkhead, a second pivot block arranged proximate the second bulkhead, and an arm rotatably coupled to the first and second pivot blocks at opposite ends of the arm. Rotation of at least a portion of the arm drives at least a portion of the arm radially outward from an axis of the downhole tool.

Abstract: A system for driving an arm radially outward from a work string axis includes a pivot block coupled to the arm at a first coupling, the arm rotating about the first coupling in a first direction to move from a stored position to an expanded position, and about the first coupling in a second direction to move from the expanded position to the stored position. The system also includes a biasing member that drives movement of the arm in the first direction. The system further includes a chamber for storing the biasing member within a pivot block diameter when the arm is in the stored position.

Abstract: A modulator is disclosed for creating a pressure pulse in a fluid-filled well. The modulator comprises a tool body on which a plurality of extendable arms are mounted. The arms may be retracted into a stowed position substantially adjacent the tool body, or may be extended to meet the wall of the borehole. The arms are preferably resilient bowsprings that may be flexed outwards from the tool by means of an actuator pushing on at least one end of the springs. A flexible valve sleeve or bag is suspended between the arms and cooperates with a valve mounted adjacent the sleeve on the tool body. The valve sleeve creates a fluid-flow path through the valve, and in operation, the valve closes one end of the valve sleeve to create the pressure pulse. Sealing of the valve sleeve against the wall of the well is a result of the fluid pressure inflating the sleeve against the well wall. As a result, sealing takes place over an extended area of the bag and is dynamically responsive to changes in fluid flow or pressure.

Abstract: A shock absorbing tool for use in pipelines and oil wells, particularly in combination with perforation guns comprises a central mass supported on two springs between the end terminal members. The shock wave is absorbed in the free oscillation of the mass. The mass is constituted by a piston assembly. A steel rope permits the shock absorbing tool to be maneuvered within the bore hole without damage to the springs.
