Inflow control device, method and system

Abstract

An inflow control device (ICD), including a hydrocyclonic device having a plurality of pressure taps therein and a valve responsive to differential pressure of the plurality of pressure taps. An inflow control device (ICD) including a switch having a primary flow inlet and a primary flow outlet, and a trigger that generates a differential pressure in the trigger due to separation of fluids having different densities. A method for allowing flow of a desired fluid while retarding a flow of undesired fluid in a flow control device, including flowing a pilot fluid through a fluid separator, separating components of the pilot fluid, applying differential pressure of two of the separated components to a valve that is actuated by differential pressure, flowing or retarding flow of a primary flow through the valve in response to the differential pressure.
