WELLBORE TOOLS WITH NON-HYDROCARBON-BASED GREASES AND METHODS OF MAKING SUCH WELLBORE TOOLS

摘要

A wellbore tool includes a non-hydrocarbon-based grease disposed between a first component and a second component. The grease remains substantially impermeable to hydrocarbons at temperatures up to at least about 150°C and possibly up to at least about 200°C, and pressures up to at least about 27 MPa and possibly to at least about 50 MPa. Methods of forming such wellbore tools include selecting a grease to comprise a non-hydrocarbon-based grease that remains at least substantially impermeable to hydrocarbons at temperatures up to at least about 150°C and possibly up to at least about 200°C, and pressures up to at least about 27 MPa and possibly to at least about 50 MPa; and disposing the grease at an interface between a first component of a wellbore tool and a second component of a wellbore tool.
