Abstract: Method for preventing the settling out of a weighting agent from a drilling fluid when the drilling fluid is substantially water free by using certain hydroxy compounds such as 1,2-ethanediol, and the drilling fluid formed by the method. Also, a method for preventing plugging of wells containing substantial amounts of sulfur.
