Abstract:
An autonomous valve includes a fluid-sensitive actuator operable to automatically actuate the valve in response to being exposed to a target fluid. The target fluid may be a fluid whose presence is generally undesirable in a production fluid, such as water, and the valve may be actuated to stop flow from an interval within a wellbore that is no longer expected to produce hydrocarbon-bearing fluids. The valve further includes a protective layer disposed between the fluid inlet and the fluid-sensitive actuator, the protective layer being insoluble in the target fluid. The fluid-sensitive actuator may include a swellable piston that swells to actuate the valve in the presence of the target fluid, a soluble plug that isolates a hydraulic, closing piston until the soluble plug is dissolved into the target fluid, and an electromechanical actuator that closes the valve in response to detecting the target fluid using an electronic sensor.

Claim (Index 1):
A method of autonomously actuating a valve for controlling flow of a production fluid from a geological formation, the method comprising:\n deploying a tubing segment in a wellbore, the tubing segment including a conduit and the valve, wherein the valve defines a fluid flow path between an inlet of the valve fluidly coupled to an exterior of the tubing segment and an outlet of the valve fluidly coupled to the conduit, the valve comprising a fluid-sensitive actuator comprising an electromechanical actuator comprising a controller, a power source, and\n an electronic sensor; and a fluid motivated piston coupled to a valve closing member, the fluid motivated piston being disposed between a fluid inlet of the fluid-sensitive actuator and a chamber at a first pressure; \n receiving the production fluid to the valve inlet; detecting a target fluid with the electronic sensor; and opening the fluid inlet of the fluid-sensitive actuator in response to detecting the target fluid to allow the production fluid to engage the fluid motivated piston to force the valve closing member to a closed position in response to the production fluid entering the fluid inlet of the fluid-sensitive actuator at a wellbore pressure that is greater than the first pressure.
