Abstract: A pumping system including a first section and a second section. The first section includes a first housing having an axial bore formed therethrough and a protruding member formed on one end of the first housing, and a first shaft arranged within the axial bore of the first housing. The second section include a second housing having an axial bore formed therethrough and a recess formed on one end of the second housing for receiving the protruding member of the first housing, and a second shaft arranged within the axial bore of the second housing. An apparatus for compensating oil volume change in a motor, including a compensator housing having an open end for connecting to the motor, and a closed end; and a flexible bladder arranged within the housing and connected to the open end of the housing.

Abstract: A technique is provided for pumping fluids in a subterranean wellbore. A submersible pumping system can be deployed in a wellbore for moving desired fluids within the wellbore. The pumping system energizes the desired fluid movement by reciprocating a working fluid between expandable members.

Abstract: A technique is provided to facilitate logging in a well environment. Downhole well related equipment is deployed in a wellbore with an internal, longitudinal passageway. A logging tool system is moved through the longitudinal passageway for performance of logging procedures within the wellbore below the well related equipment.

Abstract: A submersible electric motor in a submersible pump system is provided that facilitates connecting auxiliary tools with the motor and disconnecting auxiliary tools from the motor without draining the fluid from the motor. The motor includes electrical terminals for connecting the auxiliary tool with the motor and may include a hydraulic connector that maintains the fluid in the motor when connecting or disconnecting the auxiliary tool and provides fluid communication of the fluid between the motor and a terminal area when the auxiliary tool is connected.

Abstract: A system and method is provided for reducing the wear on a motor protector, particularly when used in an abrasive environment. The motor protector comprises an outer housing having an internal shaft. The motor protector further comprises a head section having an abrasives exclusion mechanism to reduce the amount of abrasive material contacting a specific component or components within the motor protector.

Abstract: A system and method is provided for pumping fluid. A pump incorporates composite components that provide a high degree of formability while maintaining wear resistance for use in potentially abrasive environments. The composite components may comprise one or more impellers and/or one or more diffusers.

Abstract: A system and method is provided for constructing an elongated pump. The pump has multiple stages within an outer housing. Each stage comprises an impeller and a diffuser. The diffusers are divided into separate groups that are compressed during construction of the pump.

Abstract: An electric submergible pumping system having a submergible electric motor with a unique rotor bearing system to promote longevity of the motor. The system includes an electric motor having a housing and a stator mounted within the housing. A shaft is rotatably mounted within the housing for rotation within an interior, axial passage through the stator. A rotor bearing assembly is disposed intermediate the stator and the shaft. The assembly includes a bearing sleeve mounted adjacent the shaft, and a main body portion disposed in sliding engagement with the bearing sleeve. A spring mechanism, such as a wave spring, is engaged with the main body portion. A bracelet is located between the spring mechanism and an interior surface of the stator. The spring mechanism biases the bracelet against the stator to prevent the body portion from rotating during rotation of the shaft.

Abstract: A shroud for use with a submergible pumping system. The shroud is disposed over a submergible motor and includes fluid channels for conducting heat away from the submergible motor. The shroud is formed from a sheet material, such as sheet metal, to permit its use in wellbores having a narrow annular space between the submergible pumping system and the interior surface of the wellbore casing. The sheet material includes longitudinal corrugations to facilitate fluid flow while strengthening the construction of the shroud.

Abstract: A spring cartridge rotor bearing is inserted into an electric motor during assembly as a preassembled unit. The rotor bearing includes a sleeve having a bore adapted to receive therethrough a shaft of the electric motor, and each end of the sleeve adapted to contact adjacent motor rotor sections. A bearing has a bore extending therethrough with the sleeve received therein. The bearing thermally locks into the stator bore early in motor warm-up and the bearing has sufficient end play on the sleeve to accommodate shaft expansion. One or more springs are located on the sleeve to bias the bearing to a neutral or generally centered position on the sleeve. The springs permit the bearing to move along the sleeve during times of thermal expansion and contraction, and prevent the bearing from becoming locked into an extreme position. This prevents the transmission of thrust loads from the rotor to the bearing.

Abstract: An electrical cable connector, such as a pothead for a submergible motor, employs a fluid sealing system that provides for passage of electrical conductor members through tubular bodies while preventing passage of fluid therethrough. The fluid sealing system includes semi-rigid elastomeric packing discs and gland discs. Each packing disc has flexible annular lips that seal upon either an internal surface of a tubular body or an external surface of a conductor member extending through the packing disc. Each lip has a tapered surface engaged with a corresponding annular chamfer on a gland disc; the angles or contours of the lip surfaces and the chamfers being mismatched so as to apply a radial compressive force to each lip. A compression disc is urged into engagement with a gland disc by springs surrounding a portion of the compression disc by a nut or retainer ring.

Abstract: In combination with a manually operated crimper for tightening ear clamps in which the tool has two complementary lever arms with handles at one end and jaw portions at the other end of a backup disk. A disk is positioned in a slot in the arms of the tool and encircles and rotates around the tool pivot pin. An arcuate anvil is positioned at the outer periphery of the disk and forms an outer backup surface. Anvil shoulders at each end of the anvil coact with shoulders on the arms. The disk is rotated and held adjacent the jaw portions as the jaws close for engaging the clamp ear.
