This invention relates to a composition comprising a mixture of a brine and a liquid hydrocarbon, and (A) an emulsifying amount of (i) at least one reaction product of a hydrocarbyl-substituted succinic acylating agent, and at least one of (a) ammonia, (b) an alcohol, or (c) an amine, or at least on
This invention relates to a composition comprising a mixture of a brine and a liquid hydrocarbon, and (A) an emulsifying amount of (i) at least one reaction product of a hydrocarbyl-substituted succinic acylating agent, and at least one of (a) ammonia, (b) an alcohol, or (c) an amine, or at least one salt of the reaction product; or (ii) at least one reaction product of a hydroxyaromatic compound, an aldehyde, and an amine, and (B) at least one surfactant selected from the group consisting of a polyoxyalkylene amine, a polyoxyalkylene amide, a polyoxyalkylene alcohol, a polyoxyalkylene phenol, a polyoxyalkylene ester, a fatty acid salt, an amine or an alkaline earth or transition metal sulfonate, or a reaction product of a hydroxyamine or a polyalkylenepolyamine with an acylating agent selected from the group consisting of a fatty monocarboxylic acylating agents, a dicarboxylic acylating agent other than a succinic acylating agent, and a tricarboxylic acylating agent. The compositions of the present invention have beneficial emulsion and viscosity properties. These compositions are useful in drilling, working and completing well bore holes. The compositions of the present invention have beneficial viscosity, pumping and suspension properties. These compositions are stable. The surfactants of the compositions act as wetting agents for barites and organophilic clays. The surfactants may also act as an emulsifier as well as a wetting agent.
