Patent number: 11125217Abstract: A choke for fluid connection between a manifold and a pump. The choke includes a fluid passage having an inlet, a contraction portion, a throat, an expansion portion, and an outlet. The inlet has a first diameter and the outlet has a second diameter. The throat is substantially cylindrical, having a third diameter that is substantially less than the first and second diameters. The contraction portion connects the inlet and the throat and gradually decreases from the first diameter to the third diameter along a longitudinal axis of the fluid passage. The expansion portion connects the throat and the outlet and includes a substantially cylindrical chamber having the second diameter.Type: GrantFiled: November 5, 2015Date of Patent: September 21, 2021Assignee: Schlumberger Technology CorporationInventors: Gustavo Plaza, Kim A.

Patent number: 10920553Abstract: A blender apparatus is disclosed having a chassis, a mixer positioned on the chassis, and a transfer pump positioned on the chassis. The mixer has a mixer housing defining a first mixer inlet, a second mixer inlet, and a mixer outlet. The first mixer inlet receives a liquid component, and the second mixer inlet receives a dry component. The mixer pressurizes at least the liquid component within the housing and discharges the liquid component through the mixer outlet at a first pressure above hydrostatic pressure. The transfer pump has a pump housing defining a pump inlet, a pump outlet and is devoid of an inlet configured to receive a dry component through a gravity feed. The transfer pump receives the liquid component through the pump inlet, pressurizes the liquid component within the pump housing, and discharges the liquid component through the pump outlet at a second pressure above hydrostatic pressure.Type: GrantFiled: July 10, 2019Date of Patent: February 16, 2021Assignee: Schlumberger Technology CorporationInventors: Kim A. Hodgson, Sean Black, Prashant Unnikrishnan Nair, Dale Eden, William Troy Huey, Donald E. Hensley, Olivier Clerc

Patent number: 4844161Abstract: A method and apparatus for drill pipe conveyed logging is disclosed. In a highly deviated well borehole, the apparatus comprises a hollow housing for surrounding a logging tool, lockable and releasable rotating connector joined to said housing, and weights along one side to rotate said housing against or relative to the low side of the deviated well bore. The rotating connector includes a telescoping sleeve, and can move downwardly to lock abutting shoulders, or move upwardly to permit logging tool rotation. A nonconductor housing rotatably locks with a hollow nut and compressed rings. The housing has aligned SP electrode windows aligning with SP electrodes to operate through the housing. A male wet connector enclosed in a sealed capsule is affixed at the top end of the housing and is electrically connected to the logging tool. A cooperative female wet connector in a similar closed capsule is supported on a logging cable.Type: GrantFiled: August 18, 1988Date of Patent: July 4, 1989Assignee: Halliburton Logging Services, Inc.Inventors: E.

Patent number: 4799546Abstract: A method and apparatus for drill pipe conveyed logging is disclosed. In a highly deviated well borehole, the apparatus comprises a housing for surrounding a logging tool, lockable and releasable rotating standoff means along said housing, and weights along one side to rotate said housing against or relative to the low side of the deviated well bore. The apparatus further includes rotary means joining the housing to the pipe string. A male wet connector enclosed in a sealed capsule is affixed at the top end of the housing and is electrically connected to the logging tool. A cooperative female wet connector in a similar closed capsule is supported on a logging cable. The logging cable is pumped down, mechanical connection is made, separate electrical connection between the mating connectors is made, and drilling fluid is excluded by virtue of positioning the mating connectors in separate closed capsules which are filled with a selected insulating liquid.Type: GrantFiled: October 23, 1987Date of Patent: January 24, 1989Assignee: Halliburton CompanyInventors: Donald E.

Patent number: 4700778Abstract: For use in drill pipe conveyed logging systems wherein the logging apparatus is enclosed in a housing affixed to the lower end of a drill pipe string, a system is disclosed utilizing a wet connector and overshot. The wet connector includes a centralized upstanding mechanical connector means having a J-slot cooperative with pins inserted thereinto. The J-slot is adjacent to a sleeve which telescopes over an enclosed and protected upwardly facing electrical connector means. On the overshot, the solid body thereof includes a lower appended skirt having inwardly protruding pins which engage the J-slots to achieve a separate mechanical connection. There is internally of the overshot a spring mounted telescoping and movable electrical connector including a cooperative socket engaging the plug of the wet connector. The electrical connection is kept separate from the mechanical connection so that the entire load of operation is carried separately without interfering with operation of the electrical connectors.Type: GrantFiled: July 24, 1986Date of Patent: October 20, 1987Assignee: Halliburton CompanyInventors: Michael L. Smith, Donald E. Hensley
