| 20100326694 | LONG LENGTH ELECTRO COILED TUBING AND METHOD OF MANUFACTURING SAME - Electro coiled tubing (ECT) can be utilized to provide electrical power to equipment in wells. A long length of ECT is provided with protrusions welded on the inside of the tubing at selected intervals to form support shoulders. Anchors with a load shoulder are attached to the electrical cable enclosed in the tubing such that the load shoulder contacts the support shoulder created by the welded protrusion. The weight of the electrical cable can then be transferred to the tubing via the contact between the load shoulder and the support shoulder. The protrusions are welded to the tubing and the anchors are attached to the cable during the manufacturing process. | 12-30-2010 |

| 20090291001 | CENTERING COUPLING FOR ELECTRICAL SUBMERSIBLE PUMP SPLINED SHAFTS - An electrical submersible well pump assembly having a pump, a pump motor, and a seal section. The motor drives the pump via shafts rotatingly coupled with a coupling assembly. The coupling assembly includes an alignment device that maintains the shaft ends in coaxial alignment. The alignment device compressibly engages one or both of the shafts. The alignment device may be an elongated member having slots cut along its length on one or both ends configured to compress when inserted into a bore coaxially formed into the shaft ends within the coupling assembly. | 11-26-2009 |
| 20100266248 | SYSTEM, METHOD AND APPARATUS FOR POWER TRANSMISSION CABLE WITH OPTICAL FIBER FOR DOWNHOLE TOOL IN SUBTERRANEAN APPLICATIONS - A system, method and apparatus for incorporating a fiber optic cable into a power cable for an electrical submersible pump is disclosed. The fiber optic components are protected from damage during handling of the cable with pump cable components, such as lead sheaths and jacketing materials. The optical fibers are protected from damage due to corrosive oil well chemicals and gasses, as well as protected from decompression damage. | 10-21-2010 |

| 20110037332 | Non-Sliding Carrier Bearing in Submersible Pump Motor and Method of Installation - A submersible well pump motor has features to prevent the carrier bearing from sliding axially along the stator due to thermal growth of the rotor. The rotor has a shaft and rotor sections spaced apart from each other. Carrier bearings are located between the rotor sections, each having an anti-rotation member that frictionally engages the inner diameter of the stator to prevent spinning of the carrier bearing. A deflectable thrust washer may be located between ends of the carrier bearing and the rotor sections. The thrust washer reduces in thickness in response to an axial thermal growth force due to axial thermal growth movement of the rotor sections and shaft. The thermal growth force is less than an amount of dislodging force required to cause the anti-rotation member to axially move relative to the stator. Rather than deflectable thrust washers, sacrificial thrust washers that dissolve prior to normal operation may be used. | 02-17-2011 |

| 20090068037 | Hermetically Sealed Motor Lead Tube - An electrical submersible pump assembly has a motor cooperatively engaged with a pump for driving the pump and a motor lead extending to the motor for supplying power to the motor. The motor lead has an electrical conductor enclosed within a tube. The tube is sealed from an exterior environment of the motor and contains a dielectric fluid. The motor may be filled with a dielectric lubricant and the interior of the tube of the motor lead may be in fluid communication with the dielectric lubricant. Alternatively, the motor may filled with a dielectric lubricant and the dielectric fluid within the interior of the tube of the motor lead may be sealed from the dielectric lubricant. | 03-12-2009 |
| 20090151953 | SUBMERSIBLE PUMP WITH SURFACTANT INJECTION - A submersible pumping system for use downhole that includes a housing, a pump and gas separator within the housing, a motor for driving the pump and separator, and a foaming agent injection system. The foaming agent injection system injects a foaming agent upstream of the pump and optionally upstream of the separator. The foaming agent injection system comprises a foaming agent supply, an injection pump, and foaming agent injection line. | 06-18-2009 |
| 20100186990 | High Voltage Electric Submersible Pump Cable - A cable for transmitting high voltage electricity for use with an electric submersible pump has a plurality of solid conductors for conducting electricity along the length of the cable. The solid conductors are uniformly and firmly bonded to the surrounding insulation with a thin bonding layer applied directly over the conductor. A layer of conductive fabric tape surrounds the insulation to form an outer stress control layer. The insulated conductors are surrounded by an extruded layer of lead. A second layer of fabric tape surrounds the lead. An armored outer layer surrounds the insulated conductors and the lead. Space between the insulated and wrapped conductors and the armored outer layer is filled with a jacket material. | 07-29-2010 |
