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.
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;
A composition comprising a mixture of from about 5 to about 90 parts by volume of a brine as a discontinuous phase, and from 10 to 95 parts by volume of a liquid hydrocarbon as a continuous phase, wherein the total parts by volume of brine and liquid hydrocarbon total 100 parts by volume, and (A) an emulsifying amount of at least one reaction product of a hydrocarbyl-substituted succinic acylating agent, having a hydrocarbyl group containing an average from about 8 to about 300 carbon atoms, and a hydroxyamine, or a salt of the reaction product 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 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 agent, a dicarboxylic acylating agent other than a succinic acylating agent, and a tricarboxylic acylating agent.
The composition of claim of 36 wherein the hydroxyamine is monoethanolamine, diethanolamine, triethanolamine, diethylethanolamine, dimethylethanolamine, dimethylaminopropanol, diethylaminopropranol, or aminopropanol.
A composition comprising a mixture of from about 5 to about 90 parts by volume of a brine as a discontinuous phase, and from 10 to 95 parts by volume of a liquid hydrocarbon as a continuous phase, wherein the total parts by volume of brine and liquid hydrocarbon total 100 parts by volume and (A) an emulsifying amount of (i) at least one reaction product of a hydrocarbylsubstituted succinic acylating agent, and at least one of (a) ammonia, (b) an alcohol, (c) an amine, (d) or mixtures thereof, 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 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 agent, a dicarboxylic acylating agent other than a succinic acylating agent, (C) a weighting agent, and (D) an organophilic clay.
