Water and gas barrier for hydraulic systems

A resource exploration and recovery system comprising:

• a first system;
• a second system fluidically connected to the first system by one or more tubulars;
• and
• a downhole tool carried by the one or more tubulars, the downhole tool comprising:
• a body including a hydraulic chamber;
• and
• a flexible multi-layer barrier impermeable to gas and water mounted at the body separating the hydraulic chamber from fluids external to the body, the flexible multi-layer barrier comprising:
• a first elastomeric layer;
• a second elastomeric layer;
• and
• a gas impermeable layer arranged between the first elastomeric layer and the second elastomeric layer, the gas impermeable layer being formed from a metal layer, wherein the metal layer comprises a metal having a melting point less than about 30° C.

A downhole tool, configured to operate in a subterranean environment comprising:

• a body including an inner annular wall defining a hydraulic fluid chamber;
• and
• a flexible multi-layer barrier impermeable to gas and water mounted at the body separating the hydraulic fluid chamber from fluids external to the body, the flexible multi-layer barrier comprising:
• a first elastomeric layer;
• a second elastomeric layer;
• and
• a metal layer,
• wherein the metal layer comprises a metal having a recrystallization temperature that is below a lowest temperature of the subterranean environment.
