Solid emulsifiers, drilling fluids, and methods of making and using the same

A method of enhancing or improving at least one handling property of a spray dried emulsifier composition comprising of a first emulsifier, the method comprising, consisting essentially of, or consisting of:

• providing a first emulsifier;
• preparing a second emulsifier by:
• reacting (A) a fatty acid composition with (B) one or more poly(alkylamine) to produce a partial amide;
• and
• reacting (a) the partial amide with (b) an acid and/or anhydride composition that includes or is a dicarboxylic acid, di-anhydride, tricarboxylic acid, tri-anhydride, or a mixture thereof, to produce the second emulsifier,
• wherein the fatty acid composition comprises at least about 60% C16-18 fatty acids and at least 65% saturated fatty acids;
• and
• blending the first emulsifier and the second emulsifier,
• wherein the blend of the first emulsifier and the second emulsifier has an enhancement or improvement in at least handling property relative to an emulsifier composition comprising the first emulsifier and not the second emulsifier.
