Publication number: 20230279749Abstract: A technique facilitates production of desired well fluids. A well string may comprise a plurality of well screen joints which are assembled for receipt of a well fluid from a desired well zone along a wellbore. The well screen joints are constructed and assembled in a manner which also creates a flow path to a common inflow area. At this common inflow area, the well fluid may be directed through a port or ports into an interior production passage of the well string for production to a desired collection area. The port or ports at the common inflow area may be selectively closed to block inflow of fluid from the plurality of well screen joints.Type: ApplicationFiled: June 25, 2021Publication date: September 7, 2023Inventors: Ashutosh Dikshit, Michael Plooy, Seymur Gurbanov, Nikita Vikulin

Patent number: 11512575Abstract: A technique facilitates the production of well fluid. According to an embodiment, an inflow assembly may be deployed downhole with, for example, completion equipment used in the production of well fluid. The inflow assembly comprises a first inflow control device and a second inflow control device disposed in series along a flow path routed between an exterior and an interior of the inflow assembly. As well fluid flows into an interior of the inflow assembly along the flow path, the first inflow control device and the second inflow control device perform different tasks with respect to controlling fluid flow. The different tasks may be selected to, for example, facilitate production of well fluid while protecting the completion equipment.Type: GrantFiled: February 14, 2020Date of Patent: November 29, 2022Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Ashutosh Dikshit, Glenn Woiceshyn, Amrendra Kumar

Patent number: 11174710Abstract: A technique facilitates joining of components without subsequent heat treatments. The components are joined by using a friction stir process which establishes a desired friction stir region at an appropriate location to securely join the desired components. In well applications, various components of sand screen assemblies may be joined by the friction stir process. For example, metal sand screen components may be securely coupled with a corresponding metal base pipe. The joining technique enables retention of the corrosion resistant properties of the materials without applying post weld heat treatments and/or other subsequent treatments.Type: GrantFiled: October 7, 2016Date of Patent: November 16, 2021Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Chase Cox, Ashutosh Dikshit
