Abstract: A stiffened mandrel used in the manufacture of a composite tubular. The mandrel is placed on a filament winding machine and is comprised of an outer and inner shell. A pressure source is connected to the mandrel to exert a tensile force on the outer shell to stiffen the mandrel and thereby prevent sagging and bending of the mandrel. The stiffened mandrel allows for the manufacture of a composite tubular without undesirable flexing, wrinkling, or contamination of the uncured composite.

Abstract: A subsea well tubular member has an axial passage with upper and lower retrievable plugs releasably mounted in the passage, the plugs having ends facing each other. A cavity is formed on one of the ends of one of the plugs. A movable barrier is mounted sealingly over the cavity, the barrier being movable repeatedly between inner and outer positions in response to temperature changes. The inner position reduces a volume of the cavity and increases a volume of a trapped fluid space between the ends of the plugs. The outer position increases the volume of the cavity and decreases the volume of the trapped fluid space. The barrier has two metallic layers with different coefficients of expansion.

Abstract: A running tool sets and pressure tests a bridging hanger and a packoff in a single trip. The running tool has a stem, an inner body, and a piston. The inner body is connected to the stem so that rotation of the stem relative to the inner body will cause the stem to move longitudinally. The piston is connected to the stem so that the stem and piston rotate and move longitudinally in unison. A piston engagement element is housed in the inner body and is adapted to engage the piston when the bridging hanger is set to prevent premature setting of the packoff. The piston engagement element can be disengaged once the bridging hanger is set, thereby allowing the piston to set the packoff.

Abstract: An electrical line for installation in a well for transmitting power to a well pump includes a string of coiled tubing. An electrical cable having insulated electrical conductors embedded within an elastomeric jacket extends longitudinally through the interior passage of the tubing. Body members are placed around the outer periphery of the electrical cable, and the body members are compressed onto the electrical cable through the use of an anchor assembly. The anchor assembly is held in a compressed state through the use of frangible support elements. Once the electrical cable is in place within the coiled tubing, the user applies an external force to cause the support elements to fail, thereby releasing the anchor assembly from its compressed state. The anchor assembly contacts the inner wall of the coiled tubing, such that the weight of the electrical cable is transferred to coiled tubing.

Abstract: An apparatus and method are provided for monitoring and controlling a power system of an electrical submersible pump assembly. A sensor monitors an alternating current component of a downhole electrical imbalance voltage at a neutral point of a motor of the electrical submersible pump assembly. The sensor measurement is transmitted to a controller at the surface. The controller analyzes the alternating current component of the downhole electrical imbalance voltage and then adjusting an operation of the electrical submersible pump assembly, or scheduling maintenance, accordingly. Also, a model of a power system of an electrical submersible pump assembly is created to predict an alternating current component of a downhole electrical imbalance voltage. The model is modified as necessary responsive to measurements from the sensor. A controller adjusts surface currents according to the model of the power system to match downhole motor drive currents to thereby optimize the power system.

A fastener extends through a hole in the support shoulder into engagement with the seat to prevent rotation of the seat.

Abstract: A string of conduit extending from a subsea wellhead assembly to a surface wellhead assembly on a platform has a plurality of grooved profiles on an upper portion of the conduit. Each profile is spaced axially from another of the grooved profiles. After a lower end of the conduit is secured to the subsea wellhead assembly, the operator pulls on the conduit to apply a selected tension to the conduit. The operator attaches a support ring to the profile that was closest to and above a load shoulder in the surface wellhead assembly when the desired tension was reached.

Abstract: A system for and method of supplying an injection fluid to a well assembly so that the injection fluid flows at a substantially constant flow rate. The fluid can be injected at a single site in the well assembly or multiple sites. A flow control regulator is included that attaches to the well assembly and provides a self adjusting flow control for the fluid being injected. The regulator includes a slidable floating sleeve having an orifice through which the fluid flows. The sleeve includes an inlet port that can register with a fluid supply port to allow the injection fluid to make its way into the sleeve. The fluid exits the sleeve through the orifice to generate a pressure differential across the orifice that in turn exerts a sliding force onto the sleeve. Moving the sleeve misaligns the inlet port and fluid supply port thereby throttling flow through the regulator to a predetermined flow rate.
