Combining all analysis results, the optimized formulation for recycling and reusing the flowback fluid from this well/oilfield was found to be filtered flowback fluid + 0.1 wt.% Gl-47S + 0.03 wt.% citric acid (tune pH value to 5) + 0.35 wt.% high-molecular-weight guar + 0.3 wt.% crosslinking regulator (tune pH value back to 9) + 0.36 wt.% crosslinking agent + 1 wt.% temperature stabilizing agent + 1 wt.% flowback surfactant + 1 wt.% demulsifier + traces of other additives as in the original formulation.

He said: "We had a leak of about a tonne of a demulsifier. It is not a real 'nasty' but is an irritant to skin or if breathed in.
In this paper, experiments of crude oil demulsification using ultrasound, natural sedimentation, chemical demulsifier, and the combined method of ultrasound and chemical demulsifier, respectively, at different temperatures are investigated.
Those chemical aids, known under a general name of demulsifiers, are surface active, adsorbing on the water droplets surfaces and altering their behaviour.
Demulsifier is consumed in a number of industries for demulsification of oil-water emulsion.
