Autonomous inflow control device, method, and system

Abstract

An autonomous inflow control device, including a first flow modifier and a second flow modifier disposed in series with one another, a third flow modifier and a fourth flow modifier disposed in series with one another, a first sensor, a second sensor, a valve responsive to a difference between a signal from the first sensor and a signal from the second sensor. A method for including flowing a fluid to a device, splitting the flow into a first flow path of the device and a second flow path of the device, generating a signal in a first sensor in the first flow path, generating a signal in a second sensor in the second flow path, and opening or closing a valve responsive to a differential in the signal from the first sensor and the signal from the second sensor. A borehole system including the autonomous inflow control device.
