Currently, water-based and hydrocarbon-based oil and gas well silencing fluids are widely used. The most promising liquids for silencing and developing wells are direct emulsions, whose viscosity can be regulated by changing the concentration of the “oil” phase. Urgent task is to develop polymer-free structured emulsion compositions for developing and silencing low-temperature oil and gas wells that are stable when the water phase is saturated with sodium or potassium chlorides. For use in protected areas, the developed formulations should use vegetable oils and esters based on them as the oil phase, along with hydrocarbons.
