Downhole system having isolation flow valve and method
Abstract:
A downhole system including a valve including a housing having a longitudinal axis, a flowbore within the housing for fluid flow along the longitudinal axis, an annulus within the housing, the annulus concentrically surrounding the flowbore and fluidically separated from the flowbore, a piston arrangement within the housing, the piston arrangement including a piston movable from a first position to a second position, and an electronic trigger system including an electronic trigger, a first fluid chamber, and a second fluid chamber. Activation of the electronic trigger communicates the first fluid chamber with the second fluid chamber to move the piston from the first position corresponding to a closed condition of the valve blocking flow within the annulus to the second position corresponding to an open condition of the valve permitting flow within the annulus past the piston.
