The crushed or whole oilseeds or mixture of crushed or whole oilseeds are selected to impart any one of or a combination of effects including but not limited to: an increase in drilling fluid emulsion stability in oil-based or invert emulsion fluids, decreased specific gravity of the drilling fluid, seepage loss control, filtration control, oil wetting and deflocculation/dispersion, of entrained solids and/or reduced torque and drag of the drilling string.
