Abstract:
Methods of treatment subterranean formations including providing a treatment fluid comprising a base fluid and a lubricating agent. Suitable lubricating agents may be selected from the group consisting of bismuth dialkyl dithiophosphate; tungsten disulfide; a mixture of micronized graphite and micronized metal disulfide; and any combination thereof. The treatment fluid comprising a suitable lubricating agent is introduced into a wellbore in the subterranean formation.
Abstract:
A coating composition for imparting a hydrophobic film on a target surface is provided that includes an oil of a silicone oil or a fluoropolymer oil or a combination thereof, a resin, and a dry lubricant. A solvent is present to form a solution of the oil and resin. A coating is imparted to an applicator that in turn can transfer the coating as a hydrophobic film. The coating composition is stable and able to impart hydrophobic film even after storage for several weeks at elevated temperature. The coating composition does so through the exclusion of synthetic waxes especially including silicone waxes. A kit is also provided that includes a wiper blade having the above coating composition applied along with instructions for the securement of the wiper blade to a vehicle to impart the hydrophobic film to a vehicle windshield contacted by the wiper blade.
Abstract:
The invention concerns a process for producing a dry film with a high galling resistance on a threaded element for drilling and/or operating a hydrocarbon well, characterized in that it comprises at least the following steps: ⋅ forming a stable dispersion comprising a polyamide-imide powder, a polar aprotic solvent with a boiling point of more than 180°C at 760 mm Hg, and water; ⋅ applying the dispersion to one of the ends (1, 2) of said threaded element at a temperature in the range 20°C to 40°C; ⋅ drying the coated end.
Abstract:
Embodiments of the present invention may include a macro-composition with a special structure. The structure includes a layered macro-composition made of a nanoparticle as an inner nucleus, an intermediate layer around the nucleus, and an outer layer intercalated with the nucleus or encapsulating the nucleus and the intermediate layer. A plurality of the layered macro-compositions is bonded together by bonds, so that each layered macro- composition is bonded to at least one other such layered macro-composition. Embodiments include a macro-composition made of three 3 -layered macro-compositions joined in a chain by two bonds. These macro-composition assemblies may take the shape of layered macro- compositions bonded together in chains, or forming other shapes, such as rings. Embodiments may be added to lubricants such as oil or grease, to increase their performance.
Abstract:
A method for creating an artifact for use with an optical three-dimensional measuring system includes steps of: (a) providing an artifact that comprises an inspection surface, which artifact is configured to be scanned by a non-contact sensor included in the optical three- dimensional measuring system, which artifact comprises at least one of a substantially spherical body and a turbine engine component, and which inspection surface comprises a surface of one of the substantially spherical body and the turbine engine component; (b) heating the artifact to a predetermined temperature; and (c) coating the inspection surface of the heated artifact with an approximately uniform coating of dry film lubricant.
Abstract:
A lubricating grease composition for extra heavy duty extreme pressure applications comprises a major amount of a synthetic base oil a lithium complex thickener, at least one extreme pressure agent; and at least 5 wt. % of molybdenum disulfide, based on a total weight of the lubricating grease composition.
