Abstract
A flow control valve configured to be positioned in a tubing in a borehole formed in a subsurface formation, wherein the flow control is used to regulate a flow of an injection fluid into the subsurface formation based on a vapor-transition characteristic of a fluid contained within a chamber of the flow control valve.
Claims12
An apparatus comprising:
- a flow control valve configured to be positioned downhole in a wellbore and to control a flow of an injection fluid from a fluid conduit into a subterranean formation, the injection fluid comprising elemental hydrogen (H2);
- wherein the flow control valve comprises a chamber having a variable volume and filled with a fill fluid comprising elemental hydrogen (H2) or an azeotrope of elemental hydrogen, and
- wherein the flow control valve is configured to actuate to an open configuration to provide a fluid passageway for the injection fluid to flow from the fluid conduit into the subterranean formation when a phase state of the elemental hydrogen (H2) provided as the injection fluid to the flow control valve is in a predetermined phase state.
A method comprising:
- providing an injection fluid to a fluid conduit extending downhole into a wellbore, the injection fluid comprising elemental hydrogen (H2);
- controlling a flow of the injection fluid between the fluid conduit and a subterranean formation surrounding or coupled to the wellbore using one or more flow control valves;
- wherein each of the one or more flow control valves comprises a chamber having a variable volume and filled with a fill fluid, wherein the fill fluid comprises elemental hydrogen (H2) or an azeotrope of elemental hydrogen, and
- wherein each of the one or more flow control valves is configured to actuate to an open configuration to provide a fluid passageway for the injection fluid to flow from the fluid conduit into the subterranean formation when a phase state of the injection fluid is provided to the flow control valve is in a predetermined phase state.
