A shaft coupling for connecting an upper shaft with a lower shaft within a pumping system is designed to handle a large tensile load between the upper and lower shafts. In some embodiments, the upper shaft includes a shaft ring groove and the coupling has a body and a first receiving chamber within the body that receives an end of the upper shaft. The coupling also includes an upper internal groove extending into the body from the first receiving chamber and an upper split ring that is configured to be compressed into a position occupying both the upper internal groove and the shaft ring groove of the upper shaft. Set screws compress the upper split ring into the shaft ring groove of the upper shaft. In another embodiment, the coupling includes a plurality of locking screws that extend through the body into corresponding lock screw grooves in the upper and lower shafts.

Shaft couplings for high tensile loads in ESP systems

A connector secures an ESP to coiled tubing containing a power cable. Upper and lower barriers in the connector housing define an upper chamber, a lower chamber, and a center chamber. An upper chamber dielectric fluid in the upper chamber is in fluid communication with the interior of the coiled tubing. A lower chamber dielectric fluid in the lower chamber is in fluid communication with motor lubricant in the motor of the ESP. Center chamber dielectric fluid in the center chamber is sealed from contact with the upper and lower chamber dielectric fluids by the upper and lower barriers. A thermal expansion device has a container portion for allowing center chamber dielectric fluid to expand into the container.

Coiled tubing connector to electrical submersible pump

A well pump seal section housing connects between a pump and a motor. Upper and lower retainers at upper and lower ends of the housing have outward facing cylindrical walls. A bladder has an interior in fluid communication with dielectric lubricant in the motor. Rigid upper and lower sleeves are bonded within upper and lower openings of the bladder. The sleeves slide over the cylindrical walls of the retainers and are sealed by seal rings. Fasteners secure the sleeves to the cylindrical walls.

A splice connects segments of coiled tubing and power cable together. The splice has a base and a head, each having an interior conical surface and a collet with fingers that deflect inward in gripping engagement with one of the segments in response to axial movement of the head collet and the base collet. A compression sleeve extends between the base collet and the head collet and exerts forces on the collets while the base and head are being secured together. An insulator tube slides over each of the power conductors. A retainer ring for each insulator tube grips one of the power conductors and abuts a shoulder in the insulator tube to prevent movement of the insulator tube along the power conductor.

A cushioned restraint assembly secures a limb comfortably to a structure. The assembly includes an elongated cuff configured for encircling a limb. A band is coupled to and extends along the cuff. The band is configured for securing the cuff around the limb. A strap is coupled to and extends from the cuff. The strap is configured for coupling to a structure. A cushion is coupled to an interior face of the cuff whereby the cushion is configured for positioning between the cuff and the limb.

Cushioned restraint assembly

A system for producing wellbore fluids. The system includes a pumping system deployable into tubing disposed in a wellbore, the pumping system includes a pump, a pump motor, a reservoir for containing purging fluid, and conductors in electrical communication with the pump motor. Electrical supply contacts are provided in the tubing and are connected to a downhole electrical power supply via a power cable extending along the tubing length from the surface. The conductors are engageable with the electrical supply contacts when the pumping system is landed within the tubing. Purging fluid in the reservoir can be flowed between the conductors and the supply contacts to remove conductive fluid prior to engaging the conductors and supply contacts. The conductors are selectively extended from a retracted position in the pumping system. In an alternative embodiment, the electrical supply contacts are provided at locations along the length of the tubing.

An electrical submersible pump assembly has a pump discharge head with an integrally formed pump discharge pressure port. The discharge head is mounted directly to the pump and couples the pump to production tubing. A static pressure port extends directly through the side wall of the discharge head. The pressure port includes a tubing connector for hydraulic tubing to run down to the gauge. Inside the discharge head, a flow limiter is located in the pressure port to stop the loss of fluid if there is a break in the tubing connector or hydraulic line. Alternatively, the discharge head may incorporate a venturi or other pressure drop structure to allow the fluid flow to be measured via a pressure drop across an orifice. The venturi may be configured as an insert to permit it to be replaced after it has become worn by abrasive flow.
