Patent number: 9670739Abstract: A gas lift valve system for a wellbore within a subterranean formation can include a power source that generates power, and a delivery system disposed within the wellbore and electrically coupled to the power source, where the delivery system delivers the power generated by the power source. The system can also include at least one gas lift valve assembly disposed within the wellbore and electrically coupled to the delivery system, where the at least one gas lift valve assembly receives the power from the delivery system, where at least one valve, when in a position other than a fully closed position, allows a control medium to flow from an inlet channel to an outlet channel, where the outlet channel empties into the cavity of the delivery system.Type: GrantFiled: January 7, 2016Date of Patent: June 6, 2017Assignee: CHEVRON U.S.A. INC.Inventors: Luis Phillipe Costa Ferreira Tosi, Melvin Clark Thompson, Heath Evan Lynch

Patent number: 9650865Abstract: An autonomous active flow control valve system for regulating and controlling flow across well segments is disclosed. In one example embodiment, the valve system includes a central control unit and one or more flow control devices communicatively coupled to the central control unit. Each flow control device includes at least one valve and at least one sensor for sensing various well or flow parameters. The central control unit receives sensor data from the sensor and controls the valve according to a pre-programmed control protocol. The valve may be opened, closed, and adjusted in response to detected well or flow parameters in order to maintain a desirable flow profile across well segments either in production or injection well.Type: GrantFiled: October 30, 2014Date of Patent: May 16, 2017Assignee: CHEVRON U.S.A. INC.Inventors: Namhyo Kim, Kai Sun, Luis Phillipe Costa Ferreira Tosi, Krystian K. Maskos, Thomas Gary Corbett

Publication number: 20160170417Abstract: A wirelessly controlled active inflow control valve system. The valve system includes at least one downhole zonal production control unit. The at least one zonal production control unit includes a valve configured to control an inflow of fluid, at least one sensor configured to sense at least one parameter, and a central downhole control and data acquisition unit communicatively coupled to the valve and the at least one sensor. The central downhole control and data acquisition unit sends an actuation signal to the valve and receives at least one data output from the at least one sensor. The central downhole control and data acquisition unit transmits the at least one data output to a surface control and data acquisition unit via a wireless communication protocol and receives a control command from the surface downhole control and data acquisition unit via the wireless communication protocol.Type: ApplicationFiled: December 12, 2014Publication date: June 16, 2016Applicants: CALIFORNIA INSTITUTE OF TECHNOLOGY, CHEVRON U.S.A.

Patent number: 9322389Abstract: Electrical power may be generated by way of electromagnetic induction through oscillating linear translation driven by the flow of a fluid being transported through a tubular structure. In exemplary embodiments, a conductive coil is disposed in a fixed position along a length of a tubular structure such that the conductive coil encircles the tubular structure. A linear translation apparatus is disposed radially inward from the conductive coil and is configured to move linearly parallel to a longitudinal axis of the tubular structure and within the conducting coil by harnessing mechanical energy from fluid flowing within the tubular structure. Magnets are affixed to the linear translation apparatus to cause electrical power to be generated in the conductive coil by way of electromagnetic induction responsive to the magnets passing by the conductive coil when the linear translation apparatus is in motion.Type: GrantFiled: December 19, 2013Date of Patent: April 26, 2016Assignee: Chevron U.S.A. Inc.Inventor: Luis Phillipe Costa Ferreira Tosi

Patent number: 9151415Abstract: A tubular pipe adapted for transporting oil and water may be treated upon its interior surface to reduce frictional pressure of a multiphase oil/water mixture flowing through the pipe. The tubular pipe may have an interior wall and a central cavity. In some instances, the interior surface is provided with a first textured region being adapted for reducing the adhesive forces of transported oil along the interior wall. A second region upon the interior wall may be adapted for reducing the adhesive forces of water along the interior wall of the tubular pipe. In some applications, riblets may be provided upon the interior pipe wall to further reduce the frictional forces of fluid flowing through the central cavity of the pipe.Type: GrantFiled: March 5, 2013Date of Patent: October 6, 2015Assignee: Chevron U.S.A. Inc.Inventors: Alexander Zazovsky, Luis Phillipe Costa Ferreira Tosi, Seth Thomas Taylor, Andres Zoldi, Grzegorz Jan Kusinski, Leslie Douglas Munson

Publication number: 20150152716Abstract: An improved particle or sand filtering apparatus, method and system is disclosed. The apparatus may be adapted to filter particles or sand from a particle-laden hydrocarbon fluid by employing a stacked multi-layered screen in an X-Y plane and having at least one screen comprised of a plurality of first wires and a plurality of second wires that are woven. The stacked screen may be placed within a production tubing in a wellbore for the production of hydrocarbons from the wellbore. The apparatus is configured to facilitate passage of particle-laden fluid through the screen in a direction that is substantially parallel to an X-Y plane of the screen.Type: ApplicationFiled: December 3, 2013Publication date: June 4, 2015Applicant: Chevron U.S.A.
