A downhole tool including a body having 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 including 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.

Water and gas barrier for hydraulic systems

An apparatus for protecting an electronics module used in a borehole includes a borehole string section having at least one pocket is formed and a mount associated with the at least one pocket. The mount may include a housing, a lid, a biasing member, and a securing member. The housing receives the electronics module and is seated on a seating surface, which may be formed on the at least one pocket or the mount. The lid encloses the housing within the at least one pocket. The biasing member is in operative contact with the housing. The securing member secures the lid within the at least one pocket and compresses the lid, the housing and the biasing member in the pocket. The biasing member responsively urges the housing against the seating surface and the housing hermetically seals the electronic module.

An apparatus for protecting an electronics module used in a borehole includes a borehole string section having an outer circumferential surface on which at least one pocket is formed, a mount associated with the at least one pocket, and a sleeve surrounding the section of the borehole string. The mount includes a housing, a lid, and a biasing member. The housing receives the electronics module and is seated on a seating surface of the at least one pocket. The lid encloses the housing within the at least one pocket. The biasing member is positioned between the lid and the housing. The sleeve presses the lid against the biasing member and the biasing member may responsively urge the housing against the seating surface. Related methods include protecting the electronics module with the mount.
