Methods for making emulsifiers, emulsified drilling fluids, and methods for using the same are provided. In one or more embodiments, the method for making an emulsifier can include mixing a tall oil and a triamide. The triamide can have the chemical formula:   

Methods for producing emulsifiers for oil-based drilling fluids

Cationic polymers and methods for using the same are provided. The method can include contacting an aqueous medium with a cationic polymer. The cationic polymer can include a polymer formed by reacting an aldehyde, and optionally an aldehyde-reactive compound, in the presence of a sufficient amount of guanidine to provide the polymer with a net cationic charge.

Guanidine-based polymers for separation processes

An emulsion of pitch in water preferably characterized by having a lower level of tack on drying by virtue of using as the emulsifying agent a fatty acid, a chemically modified fatty acid, a rosin acid, a chemically modified rosin acid, or combinations thereof, especially a tall oil fatty acid, or a chemically modified tall oil fatty acid, where the pitch emulsion is useful for reducing the development of fugitive dust in a dust-forming material.

Pitch emulsions

Oxidized and maleated derivative compositions, such as chemically modified oxidized and maleated tall oil fatty acid compositions, can be prepared and used in a variety of industrial applications, including as emulsifiers, corrosion inhibitors, concrete admixtures, and in reverse flotation mining applications.

Oxidized and maleated derivative compositions

An emulsion of pitch in water characterized by having a lower level of tack on drying by virtue of the incorporation of a finely divided filler, where the emulsion is useful for reducing the development of fugitive dust in a dust-forming material.

The present invention provides thermoplastic coated proppants and methods for preparing the thermoplastic coated proppants. Methods for using these proppants in subterranean well formations and hydraulic fracturing operations, for example, are also disclosed.
