Patent number: 11598154Abstract: A wellbore tool is conditioned between downhole deployments with a substantially continuous application of a conditioning fluid within the tool. Selectively removable caps connect to ends of the tool after its removal from the wellbore. If the tool is part of a downhole string, the caps are added after the tool is decoupled from the remainder of the string. The conditioning fluid is introduced into the tool through a fitting on one of the end caps; and while a fitting on the other end cap is opened to vent fluids resident within the tool. The caps are in sealing contact with a housing of the tool to retain the conditioning fluid inside the tool. A fluid supply system at the well site provides the conditioning fluid. Example conditioning fluids include a fracturing fluid, a completion fluid, a diluent, a solubilizing agent, an anti-scaling agent, a pH buffer, a liquid freezing point depressant, corrosion and oxidation inhibitors, oxygen scavengers, biocides, surfactants, and combinations thereof.Type: GrantFiled: June 30, 2020Date of Patent: March 7, 2023Assignee: BAKER HUGHES OILFIELD OPERATIONS LLCInventors: Sven Hoegger, Helmuth Sarmiento Klapper, Peter Schorling, Erik Bartscherer

Patent number: 11319753Abstract: A stator for a downhole motor configured for use in a downhole environment. includes an inner tubular member formed from a first metallic material having an outer surface and a helically lobed inner surface, and an outer tubular member comprising a second metallic material that is different from the first metallic material. The inner tubular member is connected to the outer tubular member by compressive force passing from the outer tubular member through the inner tubular member to a rigid mandrel removably disposed within the inner tubular member. The inner tubular member and the outer tubular member form the stator of the downhole motor.Type: GrantFiled: January 6, 2021Date of Patent: May 3, 2022Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Witali Huber, Gunnar Michaelis, Carsten Hohl, Erik Bartscherer, Harald Grimmer, Christian Fulda, Dorothea Marion Fischer, Thorsten Regener
