Patent number: 11713647Abstract: A technique facilitates control over flow of fluid in a variety of well applications and other applications. A flow control device is used to automatically control flow of fluids based on viscosity of the fluids. For example, the flow control device may be used to automatically allow flow of oil while blocking flow of gas and/or water. According to an embodiment, the flow control device comprises a production circuit and a metering circuit. The production circuit and the metering circuit cooperate to allow flow of a well fluid with a first viscosity and to block flow of well fluid when the well fluid has a different viscosity, e.g. relatively lower viscosity.Type: GrantFiled: June 20, 2017Date of Patent: August 1, 2023Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventor: Robert Krush

Patent number: 11293270Abstract: A technique facilitates performance of a gravel packing operation and desired zonal isolation. An apparatus, e.g. a sliding sleeve shunt tube isolation valve, may be deployed downhole and configured to facilitate a gravel packing operation and zonal isolation. By way of example, the apparatus contains a conduit which in an open position allows the flow of gravel pack slurry and in a closed position creates a barrier. In the closed position, upper and lower portions of the conduit are isolated from one another. When the apparatus is coupled with a packer and sand screens, the apparatus serves to create complete zonal isolation in, for example, an open hole alternate path system.Type: GrantFiled: December 17, 2018Date of Patent: April 5, 2022Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Scott Malone, Kameron Klauber, Nitin Verroju, Robert Krush, Michael Huh, Farhan Ahmed Omer, Chidi Nwafor

Patent number: 9422793Abstract: A technique provides a system and methodology for detecting and monitoring erosion in various environments, including downhole environments. A tracer element is located in a component such that sufficient erosion of the component due to fluid flow exposes the tracer element. A monitoring system is disposed for cooperation with the tracer element such that exposure of the tracer element is detected by the monitoring system. The monitoring system outputs appropriate data indicative of the erosion to enable adjustments to the fluid flow.Type: GrantFiled: October 17, 2011Date of Patent: August 23, 2016Assignee: Schlumberger Technology CorporationInventors: Luiz Gomes, Stephen D. Mason, Francois M. Auzerais, Robert Krush, Mehmet Parlar

Patent number: 8240382Abstract: A system for conveying fluid into a wellbore, including a tubular member, a packer, a hydrodynamic flow device, and a seal device. The tubular member is disposed in the wellbore through a first zone, a second zone, and a hydrocarbon producing zone of the wellbore. The packer is disposed adjacent to the tubular member, and is configured to at least partially isolate the hydrocarbon producing zone from at least one of the first and second zones. The hydrodynamic flow device is disposed around the tubular member and comprises a pump fluidly connected to a discharge in fluid communication with the first zone and an inlet in fluid communication with the second zone. The seal device is disposed around the hydrodynamic flow device to isolate a first annulus of the first zone from a second annulus of the second zone.Type: GrantFiled: December 21, 2009Date of Patent: August 14, 2012Assignee: Schlumberger Technology CorporationInventor: Robert Krush
