Abstract: An electrical submersible pump (“ESP”) has a seal member that carries a packer. A retainer initially retains the packer in a fixed axial position with the seal member as the ESP is lowered into a well conduit. The retainer is releasable after the packer has been set in the conduit in response to a thermal growth axial force on the seal member, enabling relative axial movement between the seal member and the packer. The seal member has annular seal rings that extend over an axial length on the tubular member that is greater than an axial length of the bore of the packer.

Abstract: An electrical submersible pump assembly has a rotary pump, an electrical motor, and a seal section. A drive shaft extends from the motor into the pump. A radial bearing for the shaft includes a bearing sleeve secured to the shaft for rotation. A bushing rotatably receives the bearing sleeve in sliding contact. A support member has a receptacle into which the bushing locates. The receptacle has a greater inner diameter than an outer diameter of the bushing, defining an annular gap. A bearing carrier has a bore into which the support member is secured against rotation and radial movement relative to the bearing carrier. A compliant member in the gap in engagement with the bushing and the support member prevents rotation of the bushing relative to the support member and allows limited radial movement of the bushing relative to the bearing carrier.

Abstract: An electric submersible pump (ESP) torque absorbtion anchor system (TAS) and a method to assemble the same are disclosed. The TAS includes a collar having an uphole end coupled to a production string and a flange formed on an outer diameter of the collar. The TAS also includes a sleeve having a rim extending radially inward from an uphole end of the sleeve. The collar is positioned in a cavity of the sleeve so that oppositely facing shoulders of the collar and the sleeve contact and transfer axial loads between the sleeve and the collar. A spring is positioned in an annulus between the sleeve and the collar and mounts to the collar and the sleeve so that rotational loading of the sleeve relative to the collar transfers to the spring.

Abstract: Systems and methods of cooling a motor of an electrical submersible pump (ESP) assembly employed in an electrical submersible subsea booster pumping system, are provided. A supporting frame structure such as an ESP mounting skid or top end assembly of a caisson having structural members exposed to environmental seawater, is modified or designed to include fluid conduits within the structural members to establish lubricant pathways for lubricant to flow. A heated/hot lubricant line connects between a supporting structure lubricant inlet port and an ESP motor lubricant outlet port. A cooled lubricant line connects between a supporting structure lubricant outlet port and an ESP motor lubricant inlet port. A pump or other fluid moving device circulates lubricant from the ESP motor to the lubricant pathways within the supporting frame structure, whereby the seawater cools the lubricant contained therein, which is then circulated back into the motor to assisting cooling the motor.

Abstract: A method of performing a wellbore operation is disclosed. A device is provided that includes a material that expands from an original shape to an expanded shape when a selected charge is applied to material. The device is placed in the wellbore in the original shape. The selected charge is applied to the material to expand the material, causing a pressure differential across the device in the wellbore. A fluid is supplied into the device to set the device in the wellbore.

Abstract: An electric submersible pump ESP is run in to a desired subterranean location with a packer attached. Once at the desired location the packer is set either using the ESP or some other source of force or pressure. After the ESP has completed the task and needs to be removed, the packer stays set and the ESP releases from it. Removal of the ESP assembly allows a valve in the packer mandrel to close to isolate the zone from which the ESP had been pumping. The ESP can be run in on coiled tubing or rigid tubing or wireline.

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: In one aspect, the disclosure provides a method of performing a wellbore operation that in one embodiment includes providing a device comprising a material that expands from an original shape to an expanded shape when a selected charge is applied to material, placing the device in the original shape in a wellbore, applying the selected charge to the material to expand the material and to cause a pressure differential across the device in the wellbore and supplying a fluid into the device to set the device in the wellbore.

Abstract: The pump can be utilized in gassy oil wells to prevent gas slugs from locking the electrical submersible pump. A shroud assembly is provided with a bottom that can be fixed to the top of a seal section connected to the top of a motor. Additional lengths of shroud can be added as the shroud assembly is lowered into the well. The electrical submersible pump can then lowered into the shroud and supported from a production tubing string. A hanger can then be attached to the production tubing string to carry the weight of the shroud assembly, motor, and seal section.

Abstract: An inlet apparatus for a well pump.

Abstract: Submersible pump power cable is inserted into a length of tubing. The device comprises an anchoring system attachable to the cable affixed to the tubing inner surface. The anchoring system includes an anchoring sleeve slideable over the cable and insertable into the tubing. Coiling the tubing with the cable and anchoring system inside energizes the sleeve into an anchoring configuration to anchor the cable within the tubing. The anchoring system continues to anchor the cable after uncoiling the tubing and inserting it into a wellbore.
