Publication number: 20240110473Abstract: Aspects of the subject technology relate to systems, methods, and computer-readable media for identifying a wellbore pressure based on a predicted pump intake loss. A pump intake pressure after an intake for a submersible pump deployed downhole in a wellbore is identified. An intake loss prediction model for identifying a virtual intake loss associated with the intake for the submersible pump as a function of one or more intake loss parameters is accessed. The virtual intake loss is identified by applying the intake loss prediction model based on intake loss prediction input of the one or more intake loss parameters. A pump intake pressure before the intake for the submersible pump is determined based on the virtual intake loss and the identified pump intake pressure after the intake.Type: ApplicationFiled: October 7, 2022Publication date: April 4, 2024Applicant: Halliburton Energy Services, Inc.Inventors: Yuzhu HU, Frank CORREDOR, Hans SJERPS, Casey Laine NEWPORT, Joshua Wayne WEBSTER, Jason Eugene HILL, Clara Susana Tandazo CASTRO

Patent number: 11313209Abstract: A self-orienting gas evading intake for a submersible pump provides an efficient, reliable and inexpensive system for pumping a downhole fluid to a surface. An intake section of a submersible pumping system may comprise a blocker sleeve disposed between an external housing and an eccentric intake. The intake section may be self-orienting such that a gas component of the fluid ascends the borehole to separate from a liquid component of the fluid. Actuation of a blocker sleeve exposes one or more ports of the external housing while blocking one or more other ports. The liquid component is drawn into the intake section through an exposed port and through one or more openings of the eccentric intake. The liquid component may then be drawn into the pump. As the liquid component comprises non-detrimental amounts, if any, of a gas component, the pump operates efficiently and effectively.Type: GrantFiled: February 23, 2018Date of Patent: April 26, 2022Assignee: Halliburton Energy Services, Inc.Inventors: Jason Eugene Hill, Donn J.

Patent number: 11174872Abstract: An electric pump may include a stack of diffusers including a first diffuser and a second diffuser. The first diffuser includes a recess therein defining an inner recess surface substantially circumscribing a primary diffuser axis. The second diffuser includes a lip projecting into the recess of the first diffuser. In response to a differential torque applied to the first and second diffusers about the primary diffuser axis, the lip of the second diffuser may engage the inner recess surface of the first diffuser, and thereby prevent relative rotation of the diffusers with respect to one another. An outer perimeter surface of the lip and the inner recess surface may define polygonal shapes or other non-circular profiles.Type: GrantFiled: April 30, 2019Date of Patent: November 16, 2021Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: Jason Eugene Hill, Joshua Wayne Webster, Wes John Nowitzki, Casey Laine Newport
