摘要： A well fluid including: (i) an oleaginous continuous phase; (ii) an N-acyl amino acid alkylamide; and (iii) a solid particulate. A method of treating a portion of a well with a particulate, the method including the steps of: (A) forming the well fluid; and (B) introducing the well fluid into the well. In addition, the N-acyl amino acid alkylamide affords an invert emulsion with a high OWR ratio, that is, greater than 40% oil by volume, for example, 70:30. The invert emulsion has a low viscosity, but can still suspend gravel. In a gravel packing application, the low viscosity of the invert emulsion fluid eliminates the need to break the emulsion during flow-back.
