PROCESS FOR BREAKING EMULSIONS IN FLUIDS FROM IN SITU TAR SANDS PRODUCTION (D#51,500 Texcan 058-F) ABSTRACT There is disclosed a process for breaking em- ulsions in fluids from in situ tar sands producing areas by adding thereto from 30 to 50 volume percent of a hydrocarbon diluent; an effective amount of a non-ionic water-soluble polyethylene oxide polymeric resin having a molecular weight in the range of 100,000 to 1,000,000 followed by the addition of 500 to 800 ppm of an alkali metal hydroxide which reacts with clays tending to stabilize the emulsion to prevent and remove clay deposits in the treating equipment. The hydroxide also enhances the ability of the resin to break the emulsion. -I-
