Fused metallic friction materials

A friction material member particularly useful in high load and temperature applications and a method for making the same are disclosed. The friction material member is made by preparing a mixture of sinterable metal particles, carbonaceous material, friction enhancers and curable polymeric resin; the mixture comprising at least about 50 percent by weight of metal particles and sufficient resin to coat and bond the metal particles, carbonaceous material and friction enhancers. The mixture is molded and the resin cured to form a piece in a solid preformed shape corresponding to the shape of the mold. Thereafter, the preformed piece is heated in a substantially oxygen free atmosphere for a time and at temperatures and pressures sufficient to fuse at least a portion of the metal particles into a sintered metal matrix. The preformed piece may be sintered to a metal backing plate during the heating step, or may be welded, brazed or soldered to the plate after heating. The resulting product may be classified as a hybrid friction material, i.e., being a cross between semi-metallic and sintered full metallic friction materials.

Higher dialkyl dimethyl ammonium clay gelling agents for unsaturated polyester compositions

Known higher dialkyl dimethyl ammonium clays can be surprisingly used as thixotropic agents in reinforced thermoset resins containing a major proportion of an unsaturated polyester and a minor proportion of styrene type monomer by employing a novel pregel process. In this process, the quaternary ammonium clay is pregelled in the styrene and the resulting pregel is then mixed with the unsaturated polyester to produce the final gel which is usually combined with glass fiber as a reinforcing agent for the production of thermoplastics. The novel clay gel compositions of the present invention have surprisingly advantageous properties, compared to the presently used fumed silica gel compositions.

Overtreated higher dialkyl dimethyl ammonium clay gellants and their use in greases

Polyolefin based greases gelled by clays overtreated by higher dialkyl dimethyl ammonium salts

Polyolefin lubricant base oils can be surprisingly gelled by layer and chain type overtreated higher dialkyl dimethyl ammonium clays preferably containing a minimum of 12% excess of the quaternary ion moiety over their ion exchange capacity. For example, an overtreated dihydrogenated ditallow ammonium montmorillonite containing a 22% excess of the quaternary ion can be used to prepare a polydecene based grease although it does not gel mineral oil lubricants. In contrast, the known clay analog of equivalent treatment gels the mineral oil but not the synthetic polyolefin lubricant under comparable conditions.

The emulsion may include an aqueous external phase and a hydrocarbon-based internal phase. The surfactant package may include one or more surfactants. The surfactant package may also include a surfactant having the general structure R—(OCH 2 CH 2 ) 9 —OH, where R is a hydrocarbyl having 12 carbon atoms, 13 carbon atoms, or 14 carbon atoms. The spacer fluid may contain at least 4.25 pounds of R—(OCH 2 CH 2 ) 9 —OH per barrel of the spacer fluid.

Methods of using drilling fluid compositions with enhanced rheology

Drilling fluid compositions include a base fluid, at least one additive chosen from an emulsifier, weighting material, fluid-loss additive, viscosifier, or alkali compound, and from 0.1 wt. % to 1 wt. %, based on total weight of the drilling fluid composition, of an ethoxylated alcohol compound having the formula R—(OCH2CH2)7—OH, in which R is a saturated or unsaturated, linear or branched hydrocarbyl group having from 8 to 20 carbon atoms. The base fluid may be an aqueous base fluid. Methods for drilling a subterranean well include operating a drill in a wellbore in the presence of a drilling fluid composition including the base fluid, the additive, and the ethoxylated alcohol compound.

Spacer fluid compositions that include surfactants

In one embodiment, a spacer fluid may comprise a base fluid and a surfactant package. The surfactant package may comprise one or more surfactants, where the surfactant package comprises a first surfactant having the chemical structure R—(OC2H4)x—OH. R may be a hydrocarbyl group having from 9 to 20 carbon atoms, and x may be an integer from 5 and 15. The first surfactant may have a hydrophilic-lipophilic balance (HLB) of from 12 to 13.5.

Lubricants for water-based drilling fluids

Embodiments are directed to a lubricant package for water based drilling fluids. The lubricant package includes water, a polyethylene glycol, and a lubricating agent. The lubricating agent includes triethanolamine, or a C 12 -C 14 alcohol ethoxylate, or a combination of triethanolamine and C 12 -C 14 alcohol ethoxylate. The weight ratio of the polyethylene glycol to the lubricating agent in the lubricant package is from 1:2 to 2:1. Embodiments are also directed to a water-based drilling fluid composition including an aqueous base fluid, one or more additives, and the lubricant package for water based drilling fluids.

Emulsifier compositions for invert emulsion fluids and methods of using the same

Drilling fluid compositions include invert emulsion fluids having an oleaginous phase, an aqueous phase, and an emulsifier composition that includes an ethoxylated alcohol compound and a polyaminated fatty acid compound. The ethoxylated alcohol compound has the formula R 1 —(OCH 2 CH 2 ) n —OH, where R 1 is a hydrocarbyl group having from 8 to 22 carbon atoms and n is from 1 to 8. The ethoxylated alcohol compound has a Hydrophilic-Lipophilic Balance (HLB) of less than or equal to 6. The polyaminated fatty acid compound has the formula R 2 —CO—NH—CH 2 —CH 2 —N(COR 2 )—CH 2 —CH 2 —NH—CO—R 3 , where R 2 is a hydrocarbyl group having from 1 to 20 carbon atoms and R 3 is a hydrocarbyl group having from 1 to 10 carbon atoms or an alkylene carboxylate group having formula —R 4 —COOH, where R 4 is a saturated or unsaturated hydrocarbylene having from 1 to 10 carbon atoms. Methods of drilling wells include operating a drill in a wellbore in the presence of drilling fluid compositions.

Spacer fluids and cement slurries that include surfactants

A well bore cementing system may comprise a spacer fluid and a cement slurry. The spacer fluid may be positioned within a well bore, and the spacer fluid may comprise a first surfactant package comprising one or more surfactants. The cement slurry may be positioned within the well bore, and the cement slurry may comprise a second surfactant package comprising one or more surfactants.

Development of retarded acid system

In one embodiment, a retarded acid system comprises an aqueous acid and a retarding surfactant. The aqueous acid may comprise from 5 wt. % to 25 wt. % of a strong acid, that is, an acid having a Ka greater than or equal to 0.01. The aqueous acid may further comprise from 75 wt. % to 95 wt. % water. The retarding surfactant may have the general chemical formula R—(OC2H4)X—OH where R is a hydrocarbon having from 11 to 15 carbon atoms and x is an integer from 6 to 10. The retarding surfactant may have a hydrophilic-lipophilic balance from 8 to 16.
