Abstract: Techniques for forming a helical rubber hose are provided. Such techniques include modified crosshead extrusion techniques in which an elastomer is melted, fed into a crosshead assembly, and extruded on a helical mandrel fed through the crosshead assembly to form a hose. In techniques described herein, relative axial and rotational motion of the mandrel and a die plate at or on the outlet or output of the crosshead assembly are kinematically matched such that the distance of relative axial movement of the mandrel per one revolution equals one pitch of the mandrel.

Abstract: A method, system, and computer-readable medium related to control of mud motors in drilling systems, of which the method includes measuring an eccentricity of rotation of a rotor in a stator of a mud motor using a rotor-position sensor, determining a torque of the mud motor based in part on the eccentricity, and selecting a fluid flow rate, a pressure, or both of fluid delivered downhole, through the mud motor, based in part on the determined torque.

Abstract: A mud motor includes a rotor and a stator. Drilling fluid received by cavities of the mud motor drives the rotor to rotate within the stator. The rotor includes one or more rotor lobes extending helically and defining a rotor pitch. The stator includes two or more stator lobes extending helically and defining a stator pitch. The rotor and the stator together define a tapered profile of the mud motor that varies proceeding from a top end of the mud motor to a bottom end of the mud motor. At least one of the rotor pitch or the stator pitch vary as proceeding from the top end of the mud motor to the bottom end of the mud motor.

Abstract: A progressing cavity pump or a positive displacement motor includes an external member having three or more lobes and an internal member extending through the external member and having one less lobe than the external member. One of the internal member and the external member rotates with respect to the other. The curvature of a profile of each of the internal member and external member is finite at all points. A ratio of a lobe volume of the external member to a valley volume of the external member enclosed between a minor external member diameter and a major external member diameter is between 0.9 and 1.2. A lobe height of the external member is related to a ratio of a minor internal member diameter to one less than the number of internal member lobes.

Abstract: A technique facilitates control over the actuation of a device by utilizing a rotor and a corresponding stator system. The technique employs a rotor and a corresponding stator component in a progressive cavity type system. The rotor and corresponding stator component are mounted such that rotational and/or axial motion may be imparted to at least one of the rotor or stator components relative to the other component. The controlled rotation may be utilized in providing controlled motion of an actuated device via the power of fluid moving through the progressive cavity type system.

Abstract: An apparatus, system, and method for mapping a conduit wall, of which the apparatus includes a shaft defining a central longitudinal axis, and a sensor module coupled to the shaft and including an emitter configured to emit a light beam directed at least partially radially with respect to the central longitudinal axis, and a sensor configured to detect a reflected portion of the light beam, such that the sensor module is configured to measure a distance between the conduit wall and sensor module. The apparatus also includes a centralizer coupled to the shaft and configured to position the sensor module at a center of the conduit.

Abstract: A technique facilitates efficient well production in relatively low volume applications, e.g. applications after well pressure and volume taper off for a given well. According to an embodiment, use of an electric submersible progressive cavity pump is enabled in harsh, high temperature downhole environments. A pump stator facilitates long-term use in such harsh environments by providing a composite structure having an outer housing and a thermoset resin layer located within the outer housing and secured to the outer housing. The thermoset resin layer is constructed with an internal surface having an internal thread design. Additionally, an elastomeric layer is located within the thermoset resin layer and has a shape which follows the internal thread. In this manner, the elastomeric layer is able to provide an interior surface generally matching the shape of the internal thread of the thermoset resin layer and arranged for interaction with a corresponding pump rotor.
