Non-Emulsifier products are field proven, proprietary formulations of blended nonionic surfactants added into the stimulation fluids to reduce the emulsion tendency of fluids with residual oils in formation. Water-based fracturing fluids can form emulsions with the residual oil in the formation during or after fracturing. Non-Emulsifiers can be added into the stimulation fluids to reduce the emulsion tendency of fluids with residual oils in formation. The main function of a non-emulsification agent is to break such an emulsion in-situ before the stimulated well is put back to production. Another function of the non-emulsifier is to speed up the separation of water and oil from the initial well flow-back fluid.
SunStimSTR-121L is a nonionic non-emulsifier designed for application in fracturing operations. The product effectively breaks water blocks and prevents or removes crude oil in water emulsions. It functions by reducing the interfacial tension between brines and crude oils. The product has proven to have broad spectrum performance in a wide variety of crudes throughout world.
