Abstract
Treatment fluids and associated methods and systems for demulsifying an emulsified well fluid. An example method includes contacting the emulsified well fluid with a treatment fluid comprising: an aqueous base fluid; an alcohol; a resin alkoxylated oligomer; a polyol; and a polyamine polyether. The emulsified well fluid is separated into an aqueous phase and an oleaginous phase after contact with the treatment fluid.
