Abstract: An embodiment of a method of manufacturing a fiber optic cable includes selecting a cable support structure configured to support an optical fiber sensor, adhering the optical fiber sensor to the cable support structure by applying a temporary adhesive, and installing a protective layer around the cable support structure and the temporarily adhered optical fiber sensor. The method further includes removing a bond between the optical fiber sensor and the temporary adhesive, wherein removing the bond includes injecting a debonding material into a space formed between the cable support structure and the protective layer, and injecting a permanent adhesive into the space, the permanent adhesive configured to immobilize the optical fiber sensor relative to the protective layer and allow strain to be transferred from the protective layer to the optical fiber sensor.

Abstract: The position of a movable downhole component such as a sleeve in a choke valve is monitored and determined using an array of sensors, preferably Hall Effect sensors that measure the strength of a magnetic field from a magnet that travels with the sleeve. The sensors measure the field strength and output a voltage related to the strength of the field that is detected. A plurality of sensors, with readings, transmits signals to a microprocessor to compute the magnet position directly. The sensors are in the tool body and are not mechanically coupled to the sleeve. The longitudinal position of the sleeve is directly computed using less than all available sensors to facilitate the speed of transmission of data and computation of actual position using known mathematical techniques.

Abstract: An insert meter can be run into an inverse venturi on wireline and make use of the existing pressure taps to allow accurate measurement of reduced flow rates that could not be accurately measured with the inverse venturi meter. The insert meter has seals and can lock into position with peripheral sealing to direct the new and lower flow rate into the throat of the insert meter that is preferably a standard venturi. The venturi devices can be in meter or eductor service and located downhole, subsea or on the surface.

Abstract: An annular choke mechanism is incorporated into a flow path within the outer housing of the sleeve valve to the interior flow ports of the sliding sleeve member. As the sliding sleeve member is moved axially within the housing, the lateral fluid ports of the sliding sleeve member are aligned within particular bore portions so that the size of the annular space between the fluid ports in the housing and the fluid ports in the sleeve is varied. The annular flow area through the annular space governs the rate of fluid flow through the valve.
