Abstract: An oil-based drilling fluid and a method for maintaining viscosity of an oil-based drilling fluid over a temperature range of about 120° F. to about 40° F. The oil-based drilling fluid comprises a quaternary ammonium ion having a corresponding quaternary ammonium salt having a neat shear strength value less than 6000 lb/100 ft2. The organoclay drilling fluid additive imparts a first high shear viscosity to the oil-based drilling fluid at temperatures of 40° F. or less and imparts a second high shear viscosity to the oil-based drilling fluid at temperatures greater than or equal to 120°, wherein the difference between the first high shear viscosity and the second high shear viscosity is less than 110%. The organoclay drilling fluid additive, further imparts a first low shear viscosity to the oil-based drilling fluid at temperatures of 40° F. or less and imparts a second low shear viscosity to the oil-based drilling fluid at temperatures greater than or equal to 120° F.

Abstract: Viscoelastic surfactant based aqueous fluid systems useful as thickening agents in various applications, e.g. to suspend particles produced during the excavation of geologic formations. The surfactants are zwitterionic/amphoteric surfactants such as dihydroxyl alkyl glycinate, alkyl ampho acetate or propionate, alkyl betaine, alkyl amidopropyl betaine and alkylimino mono- or di-propionates derived from certain waxes, fats and oils. The thickening agent is used in conjunction with an inorganic water-soluble salt or organic additive such as phthalic acid, salicylic acid or their salts.
