Abstract:
A downhole tool and method of operation thereof is provided. The downhole tool may be configured to permit fluid communication between a combined flowbore of the casing string and the downhole tool and the subterranean formation or wellbore, or both, after a pressure test has been completed, a second threshold pressure is reached or applied, and a third threshold pressure has been applied to the downhole tool.

Claim (Index 1):
A downhole tool, comprising:\n a housing having a longitudinal axis and defining a plurality of fluid apertures circumferentially disposed about the longitudinal axis; an inner annular casing disposed in the housing and defining a flowbore extending axially therethrough, the housing and the inner annular casing defining an annular space therebetween, and the inner annular casing further defining a casing flowpath and a port configured to fluidly couple the flowbore and the casing flowpath; a first piston disposed in the casing flowpath; an annular sleeve disposed in the annular space and coupled to or integral with the first piston, the annular sleeve configured to be displaced in a first direction by the first piston at a first pressure applied to the flowbore; a biasing member disposed in the annular space and configured to displace the annular sleeve in a second direction at a second pressure applied to the flowbore; and a second piston at least partially disposed in the annular space and configured to be displaced in the first direction by a third pressure applied to the annular space via the flowbore, such that the plurality of fluid apertures and the flowbore are fluidly coupled.
