Patent number: 9441633Abstract: A submersible well pump assembly include a rotary pump driven by an electrical motor. A seal section operably connects between the motor and the pump for reducing a pressure differential between motor oil in the motor and well fluid surrounding the pump assembly. The pump assembly contains a sealed fluid. A sensor mounted to the well pump assembly detects contamination of the sealed fluid by well fluid encroaching into contact with the sealed fluid. The sensor may be mounted in the motor or the seal section to detect well fluid contamination of motor oil. The sensor may be mounted in a secondary pump that has that has temporary barriers to block the entry of well fluid into a buffer fluid contained in the secondary pump while the secondary pump is in a storage condition within a well.Type: GrantFiled: October 2, 2013Date of Patent: September 13, 2016Assignee: Baker Hughes IncorporatedInventors: Ketankumar K.

Patent number: 9410380Abstract: Systems and methods for installing an optical fiber in a downhole equipment system having multiple components that are installed in the field. Components such as sections of an ESP motor are assembled, forming a continuous sealed conduit that extends through the components. The conduit is sealed to prevent potentially damaging fluids from leaking into the conduit. After the conduit through the components is formed, an optical fiber is inserted into the conduit so that the fiber spans the connections between the components. The optical fiber may incorporate multiple sensors (e.g., fiber Bragg gratings) that can sense parameters such as temperature at multiple points in the different components. The passageways through the different components may have different diameters or tapered/chamfered edges to facilitate insertion of the optical fiber in the conduit.Type: GrantFiled: May 2, 2013Date of Patent: August 9, 2016Assignee: Baker Hughes IncorporatedInventors: Risa Rutter, Ketankumar K.

Patent number: 9133849Abstract: A centrifugal pumping system having a stack of impellers and diffusers for pressurizing fluid. The impellers are rotated by a motor for pressurizing and lifting fluid from within a wellbore. Undulating profiles are provided on leading edges of the impellers for inducing turbulence in the fluid being pumped. Increasing turbulence better homogenizes the fluid, so that choked flow is avoided when different density components are present in the fluid. Reducing the possibility of choked flow increases pump efficiency and lift capacity.Type: GrantFiled: November 9, 2012Date of Patent: September 15, 2015Assignee: Baker Hughes IncorporatedInventors: Ketankumar K. Sheth, Suresha R. O'Bryan, Risa Rutter

Patent number: 8328529Abstract: 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.Type: GrantFiled: January 30, 2009Date of Patent: December 11, 2012Assignee: Baker Hughes IncorporatedInventors: Joseph Scott Thompson, Kevin R.
