Abstract: The present invention relates to mixtures of sulfonated thermoplastic polymers and sulfonated elastomeric polymers which function as viscosification agents when added to oil-based drilling muds which are the fluids used to maintain pressure, cool drill bits, and lift cuttings from the holes in the drilling operation for oil and gas wells. The sulfonated thermoplastic and elastomeric polymers both have about 5 to about 200 meq. of sulfonate groups per 100 grams of the sulfonated thermoplastic or elastomeric polymers, wherein the sulfonated groups are neutralized with a metallic cation or an amine or ammonium counterion. A polar cosolvent can optionally be added to the mixture of oil drilling mud and sulfonated thermoplastic and elastomeric polymers, wherein the polar cosolvent increases the solubility of the sulfonated thermoplastic and elastomeric polymer in the oil drilling mud by decreasing the strong ionic interactions between the sulfonate groups of the sulfonated polymers.
