Lubricant compositions having at least one base oil composition including about 1.0 to about 15.0 wt % water, and a friction-reducing composition including a glycerol or thioglycerol compositions are described. Methods for making such lubricant compositions and methods of drilling using such lubricant compositions are also described.

Lubricant compositions comprising diol functional groups and methods of making and using same

A lubricant compositions having at least one base oil composition and a friction-reducing composition including a substituted phosphate ester and/or substituted hydrogen phosphites are described. Methods for making such compounds and methods of drilling using such lubricant compositions are also described.

Lubricant compositions containing phosphates and/or phosphites and methods of making and using same

A method for improving wear control, while maintaining or improving fuel efficiency, in an engine or other mechanical component lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition including a lubricating oil base stock as a major component, and (i) at least one transition metal salt of a carboxylic acid (e.g., zinc stearate) or (ii) a mixture of at least one transition metal salt of a carboxylic acid (e.g., zinc stearate) and at least one detergent (i.e., an alkali metal or alkaline earth metal salt of an organic acid, or an alkali metal or alkaline earth metal salt of an inorganic acid, or an alkali metal or alkaline earth metal salt of a phenol, or mixtures thereof (e.g., calcium salicylate and/or magnesium sulfonate)), as a minor component. The lubricating oils are useful in internal combustion engines.

Lubricating oil compositions with engine wear protection

Provided are low friction coatings with improved abrasion, wear resistance and methods of making such coatings. In one form, the coating includes: i) an under layer selected from the group consisting of CrN, TiN, TiAlN, TiAlVN, TiAlVCN, TiSiN, TiSiCN, TiAlSiN and combinations thereof, wherein the under layer ranges in thickness from 0.1 to 100 &#x3bc;m, ii) an adhesion promoting layer selected from the group consisting of Cr, Ti, Si, W, CrC, TiC, SiC, WC, and combinations thereof, wherein the adhesion promoting layer ranges in thickness from 0.1 to 50 &#x3bc;m and is contiguous with a surface of the under layer, and iii) a functional layer selected from the group consisting of a fullerene based composite, a diamond based material, diamond-like-carbon and combinations thereof, wherein the functional layer ranges from 0.1 to 50 &#x3bc;m and is contiguous with a surface of the adhesion promoting layer.

Low friction coatings with improved abrasion and wear properties and methods of making

Provided are lubricant compositions and hydrocarbon fluids including one or more lubricant base stocks and an effective amount of one more zero SAP antiwear additives and/or corrosion inhibitor additives, wherein the one more antiwear and/or corrosion inhibitor additives include one or more functionalized polyolefins having one or more pyridazine moieties. Such compositions exhibit improved anti-wear, friction reduction and anti-corrosion properties.

Functionalized polymers and oligomers as corrosion inhibitors and antiwear additives

A method for improving wear protection in an engine lubricated with a lubricating oil by using as the lubricating oil a formulated oil having a HTHS viscosity of less than 2.6 cP at 150&#xb0; C. The formulated oil has a composition including a major amount of a lubricating oil base stock and a minor amount of metal phosphate nanoplatelets. The metal phosphate nanoplatelets are dispersed in the lubricating oil base stock sufficient for the formulated oil to pass wear protection requirements of one or more engine tests selected from TU3M, Sequence IIIG, Sequence IVA and OM646LA. Also provided are lubricating engine oil composition having improved wear protection.

Enhanced durability performance of lubricants using functionalized metal phosphate nanoplatelets

Provided are coated oil and gas well production devices and methods of making and using such coated devices. In one form, the coated device includes one or more cylindrical bodies, hardbanding on at least a portion of the exposed outer surface, exposed inner surface, or a combination of both exposed outer or inner surface of the one or more cylindrical bodies, and a coating on at least a portion of the inner surface, the outer surface, or a combination thereof of the one or more cylindrical bodies. The coating includes one or more ultra-low friction layers, and one or more buttering layers interposed between the hardbanding and the ultra-low friction coating. The coated oil and gas well production devices may provide for reduced friction, wear, erosion, corrosion, and deposits for well construction, completion and production of oil and gas.

Coated oil and gas well production devices

Provided are coated sleeved oil and gas well production devices and methods of making and using such coated sleeved devices. In one form, the coated sleeved oil and gas well production device includes one or more cylindrical bodies, one or more sleeves proximal to the outer diameter or inner diameter of the one or more cylindrical bodies, hardbanding on at least a portion of the exposed outer surface, exposed inner surface, or a combination of both exposed outer or inner surface of the one or more sleeves, and a coating on at least a portion of the inner sleeve surface, the outer sleeve surface, or a combination thereof of the one or more sleeves. The coating includes one or more ultra-low friction layers, and one or more buttering layers interposed between the hardbanding and the ultra-low friction coating. The coated sleeved oil and gas well production devices may provide for reduced friction, wear, erosion, corrosion, and deposits for well construction, completion and production of oil and gas.

Coated sleeved oil and gas well production devices

Provided are drill stem assemblies with ultra-low friction coatings for subterraneous drilling operations. In one form, the coated drill stem assemblies for subterraneous rotary drilling operations include a body assembly with an exposed outer surface including a drill string coupled to a bottom hole assembly, a coiled tubing coupled to a bottom hole assembly, or a casing string coupled to a bottom hole assembly and an ultra-low friction coating on at least a portion of the exposed outer surface of the body assembly, hardbanding on at least a portion of the exposed outer surface of the body assembly, an ultra-low friction coating on at least a portion of the hardbanding, wherein the ultra-low friction coating comprises one or more ultra-low friction layers, and one or more buttering layers interposed between the hardbanding and the ultra-low friction coating.
