摘要： 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 fatty acid material comprising, 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.

摘要： A low gravity solid tolerant emulsifier and methods of making the same is provided. The emulsifier includes a maleated amido-amine reaction product produced by: (1) reacting a fatty acid material including rosin acid at a concentration of about 11% to about 50%, 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. Invert emulsion fluids and drilling fluids that include the emulsifier above and methods of using the same is further provided.
