Abstract
An inflow control device (ICD) that may include a piston located in a flow passage, a barrier that prevents fluid flow through the ICD, and a shear device that prevents movement of the piston. A method of actuating one or more ICDs may include preventing actuation of the devices by maintaining a pressure in an interior of a well tool (or tubing string) below an actuation pressure of the devices, where each device may include a piston located within a flow passage, a barrier that prevents fluid flow through the ICD, and a shear device that initially prevents movement of the piston. The method may include increasing the pressure in the well tool (or tubing string) to be greater than or equal to the actuation pressure, thereby shearing the shear device and moving the piston.
