Patent number: 9958104Abstract: A motor lead extends alongside an electrical pump assembly for supplying electrical power to the motor. The motor lead has electrical power wires positioned side-by-side in a sub assembly. Each of the electrical power wires has an electrical conductor encased in an insulation layer, which in turn is encased in a lead sheath. A metallic band armor wraps around the sub assembly. A thermal barrier layer is located between an inward facing side of the sub assembly and the pump assembly. The thermal barrier layer is formed of thermal insulation material and has a width at least equal to a width of the sub assembly. The motor lead is free of any thermal barrier layers on the outward facing side of the sub assembly to as to allow heat within the sub assembly to dissipate outward.Type: GrantFiled: December 29, 2014Date of Patent: May 1, 2018Assignee: Baker Hughes, a GE Company, LLCInventors: Ty L. Baker, Leslie C. Reid

Patent number: 9938806Abstract: A well pump assembly has a main pump suspended on a string of production tubing within casing in a well. A charge pump is located below the main pump. An annular sealing element between the charge pump intake and the charge pump discharge seals between the charge pump and the casing. A motor is coupled with the main pump and the charge pump. A bypass member has an open upper end above the main pump intake and a lower end above the sealing element. The bypass member defines a flow path from the discharge of the charge pump upward past the main pump intake, then downward to reach the main pump intake. The bypass member may be a bypass riser extending alongside the main pump, or it may be a shroud surrounding the main pump.Type: GrantFiled: December 30, 2015Date of Patent: April 10, 2018Assignee: Baker Hughes, A GE Company, LLCInventors: Jordan D.

Patent number: 9920611Abstract: A well pump assembly includes rotary pump and a submersible motor. A shroud surrounds the pump intake and the motor. The shroud has an open upper end in fluid communication with the pump intake. A tubular member of smaller diameter is secured to and extends downward from a lower end of the shroud. The tubular member may have an open lower end for drawing well fluid along a lower flow path up the tubular member to the pump intake. An upper flow path at the upper end of the shroud may have a minimum flow area that is smaller than a minimum flow area of the lower flow path. The tubular member has a smaller outer diameter than an outer diameter of the shroud. The tubular member may have a closed lower end to define a debris collection chamber with a drain valve.Type: GrantFiled: March 29, 2017Date of Patent: March 20, 2018Assignee: Baker Hughes, a GE Company, LLCInventors: Leslie C.

Patent number: 9856721Abstract: A well pump assembly has a motor operatively connected to a well pump that has an intake. The well pump assembly has a capillary tube that extends alongside the tubing and has an outlet at the well pump assembly. A chemical injection pump is connected to an upper end of the capillary tube adjacent a wellhead of the well. A logic system detects well fluid falling back downward in the tubing and out the intake into the well, and in response turns on the chemical injection pump, which pumps a chemical down the capillary tube into the well adjacent or within the well pump assembly. Once upward flow of well fluid in the tubing has been established, the chemical injection pump may be turned off.Type: GrantFiled: April 8, 2015Date of Patent: January 2, 2018Assignee: Baker Hughes, a GE Company, LLCInventors: Leslie C.

Patent number: 9765608Abstract: A lower separator located below a submersible well pump intake has a labyrinth flow path, causing a first well fluid separation of lighter components from heavier components as well fluid flowing into the lower separator turns downward to flow toward a lower separator heavier component port. A bypass riser has a bypass riser inlet below the pump intake and a bypass riser outlet above the pump intake. A lighter component conduit communicates the bypass riser inlet with lighter components of the first well fluid separation, causing a second well fluid separation at the riser outlet as a heavier portion of the lighter components flowing up the riser turn to flow downward to the pump intake. A heavier component conduit bypasses the bypass riser inlet and delivers the heavier components of the first well fluid separation to the pump intake.Type: GrantFiled: January 5, 2016Date of Patent: September 19, 2017Assignee: Baker Hughes IncorporatedInventors: Rachel Sims, Artur Solodkiy, Leslie C.

Patent number: 8141625Abstract: A submersible well pump assembly in a wellbore; the pump assembly includes a liquid lift pump and a booster pump for pumping a two-phase mixture of gas and liquid. A shroud with an opening at its upper end partially encloses the pump assembly. An annulus is formed between the shroud and the wellbore inner circumference. Two phase fluid from the booster pump exits the shroud through a port and flows up the annulus to the shroud opening. Liquid in the two-phase flow separates from the gas and flows into the shroud opening and onto the liquid lift pump. The gas continues to flow up the wellbore, past the shroud opening, to the wellbore entrance.Type: GrantFiled: June 17, 2009Date of Patent: March 27, 2012Assignee: Baker Hughes IncorporatedInventor: Leslie C.
