ABSTRACT OF THE INVENTION By the use of small amounts of novel amide resin reaction products of dibasic dimerized or trimer- ized fatty acids, an alkanolamine and a polyalkylene polyamine, improved drilling mud formulations are ob- tained. In those oil mud drilling formulations that contain organophilic clays, one is able to maximize the viscosity and gelation of the formulations, resulting in less preparation time and less material usage, es- pecially the clay. In accordance with the invention, one is able to thicken or gel oil-mud systems at usual operating temperatures even when using low viscosity/ low aromatic oils as the external phase, and to maximize the yield of organophilic clays readily in a short period of time, at low shear rates. The amide resin extends the utility of organophilic clays in low vis- cosity oil-mud systems. They produce more shear thin- ning fluids, higher yield points and quicker gel stre- ngths while maintaining low plastic viscosities.
