Patent number: 11008810Abstract: A rotary valve can include a housing, a manifold with multiple flow paths can be fixedly mounted to the housing. A rotary actuator with a first surface can be rotatably mounted within the housing, and a valve seat with a second surface can be fixedly attached to the manifold, where the second surface can sealingly engage the first surface. The rotary actuator can include a gap that selectively aligns with respective ones of valve seat ports as the rotary actuator rotates relative to the valve seat, thereby selectively pressurizing one or more actuators. A system and method can include a rotary valve that selectively causes pads to extend at a predetermined orientation in the wellbore to steer a drill bit. The azimuthal orientation of a rotary actuator of the valve can determine which pads are extended and which are retracted as the drill bit rotates.Type: GrantFiled: July 17, 2017Date of Patent: May 18, 2021Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: Daniel Winslow, Larry Chambers, Neelesh Deolalikar

Patent number: 10987707Abstract: The group of inventions relates to the oil-and-gas extraction industry, in particular to equipment for removing deposits of asphaltenes, resins, paraffins, hydrates, calcium salts, etc. from tubing strings of oil and gas wells without extracting said tubing strings from the wells. This instrument can also be used for cleaning water-extracting wells and other wells. The internal surface of a tubing string is cleaned by a combined action (ultrasonic, mechanical, heat) on contaminants. Owing to the fact that operation of a well does not stop, dirt atomized by the combined action is raised to the surface and removed from the well by a stream of fluid. A system for ultrasonic cleaning of a tubing string consists of an ultrasonic generator and a downhole ultrasonic scraper, which comprises a converter converting electrical vibrations into mechanical vibrations, which is placed into a protective casing and is connected to a vibration transformer, which boosts the amplitude of vibrations of ultrasonic transducers.Type: GrantFiled: November 15, 2017Date of Patent: April 27, 2021Assignee: ILMASONIC-SCIENCE LIMITED LIABILITY COMPANYInventors: Alexandr Alexeevich Saltykov, Yuriy Alexeevich Saltykov, Andrey Alexandrovich Rukhman
