Zusammenfassung:An invert emulsion drilling fluid, and a method of drilling with such fluid, having improved rheology effected with addition of a fatty dimer diamine additive in the presence of little or no lime. The drilling fluids of the present invention exhibit similar yield points and gel strengths at temperatures ranging from about 40°F to about 375 °F or higher and at pressures ranging from about 0 psi to about 13500 psi.
