Patent number: 11892421Abstract: An electrical stability testing device includes a cup configured to receive a fluid sample. The testing device also includes a pair of electrodes positioned at least partially within the cup. The electrodes are spaced apart from one another by a predetermined gap. The electrodes are configured to have the fluid sample positioned within the predetermined gap while performing an ES test on the fluid sample in the cup. The testing device also includes a wiper positioned at least partially within the cup. The wiper is configured to pass between the electrodes after the ES test has concluded. A width of the wiper is greater than the predetermined gap between the electrodes. The wiper is configured to deform as the wiper passes through the predetermined gap such that the width becomes substantially equal to the predetermined gap and sides of the wiper contact ends of the electrodes to clean the electrodes.Type: GrantFiled: December 6, 2021Date of Patent: February 6, 2024Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Timothy Lesko, Jerry Thomas Connaughton, Zakhar Chizhov, Kenneth Slater, Bojan Mitric, Mauricio Tassano

Patent number: 10532381Abstract: A method, apparatus and system for flowing a fluid from an inlet flush nozzle onto tiered plates in a trough is provided. Material may fall from a deck in a vibratory separator, such as a shale shaker, into the trough, which is attached to the separator. The trough has a main inlet and the inlet flush nozzle that opens to tiered plates. An external pipe may feed the fluid into the main inlet and the inlet flush nozzle to lubricate the tiered plates in the trough. Material falling from the vibratory separator may float on the fluid to flow toward an outlet of the trough. A single plate with perforations may be used instead of the tiered plates to permit the fluid to penetrate the perforations to suspend the material, allowing the material to flow across the single plate to an outlet.Type: GrantFiled: November 24, 2015Date of Patent: January 14, 2020Assignee: M-I L.L.C.Inventors: Colin Stewart, Zakhar Chizhov, Mazin Philip, Mandeep Singh Ahuja, Richard Bingham
