Definitions

  • This disclosure relates to a system and method for controlling flow in a pipe string using a finger valve.
  • Multi-stage fracturing is a method that involves pumping large amounts of pressurized water or gel, a proppant and/or other chemicals into the wellbore to create discrete multiple fractures into the reservoir along the wellbore.
  • proppant fracturing usually involves multiple steps and requires several tools in order to be performed successfully.
  • Such practice that will allow even distribution of proppant between fractures, highly depends on setting plugs between the fracture stages or using frac balls of increasing sizes.
  • plugs are either set after each fracture has been perforated and pumped, or frac balls are dropped from the surface to successively open fracturing valves placed along the well.
  • balls of different diameters are dropped into the well corresponding to a specific fracturing valve's seat. At a point in the well, the ball will no longer pass through due to a decrease in well diameter.
  • fracturing can take place. After fracturing, the plugs must be drilled out and the balls must be recovered.
  • EP 2 360 347 A describes an apparatus for a drop ball activated device, where a ball seat is concentrically and axially slideably disposed within an outer sleeve having a first internal cylindrical surface, where the seat ball comprises at least one radially extending lug, which in a first position extends radially inwards from the internal cylindrical surface, thereby defining a first ball seat diameter less than the diameter of the drop ball.
  • a finger valve comprising a base pipe and a sliding sleeve.
  • the base pipe can comprise a finger port, one or more fingers; and one or more hinges, each of the hinges connecting one of the fingers to the base pipe.
  • the sliding sleeve can comprise a sliding sleeve having a first sleeve with in inner surface comprising a void and a depressor.
  • the first sleeve can be positionable in a first position and a second position. In the first position, the depressor can push the one or more fingers into a closed position. In the second position, the void can rest at least one of the one or more fingers, allowing the at least one of the one or more fingers to move into an open position.
  • the disclosure also describes a method for controlling flow in a pipe string using a finger valve, comprise the steps connecting a base pipe within a pipe string, and actuating a sliding sleeve from a first position to a second position.
  • the base pipe can comprise a finger port, one or more fingers; and one or more hinges, each of the hinges connecting one of the fingers to the base pipe.
  • the sliding sleeve can comprise a first sleeve having an in inner surface with a void and a depressor. In the first position, the depressor can push the one or more fingers into a closed position. In the second position, the void can rest at least one of the one or more fingers, allowing the at least one of the one or more fingers to move into an open position.
  • Described herein is a system and method for controlling flow in a pipe string using a finger valve.
  • the following description is presented to enable any person skilled in the art to make and use the invention as claimed and is provided in the context of the particular examples discussed below, variations of which will be readily apparent to those skilled in the art.
  • not all features of an actual implementation are described in this specification. It will be appreciated that in the development of any such actual implementation (as in any development project), design decisions must be made to achieve the designers' specific goals (e.g., compliance with system- and business-related constraints), and that these goals will vary from one implementation to another.
