Abstract:
The present disclosure provides a low gravity solid tolerant emulsifier and methods of making the same. The emulsifier includes a maleated amido-amine reaction product produced by: (1) reacting a low titer fatty acid material comprising rosin acid, and an amine material (e.g., a amine having a amine value of about 700 to about 1300 mg/g, such as AMINE HST) to produce an amido-amine reaction product; and (2) reacting the amido-amine reaction product with maleic anhydride to produce the maleated amido-amine reaction product. The present disclosure further provides invert emulsion fluids and drilling fluids that include the emulsifier of the present disclosure and methods of using the same.

Claim (Index 5):
The emulsifier of  claim 1 , wherein the low titer fatty acid material includes at least one of:\n a side stream from the oil collected as the bottoms product during the production of low rosin (<5%) and low Gardner Color index (<7.0) tall oil fatty acid (TOFA) from refinery columns during the distillation of crude tall oil (CTO); a mixture of the side stream and at least one of distilled tall oil, TOFA, rosin, or a combination thereof; a product stream of the CTO refining process; a mixture of TOFA and distilled tall oil; a mixture of distilled tall oil and rosin; a mixture of TOFA and rosin; a disproportionated tall oil, a mixture of disproportionated tall oil and rosin, a mixture of disproportionated tall oil and TOFA, a mixture of disproportionated tall oil and distilled tall oil, or a combination thereof; or a combination thereof.
