LIQUID COMPOSITION FOR INTENSIFYING OIL OR GAS PRODUCTION Russian patent published in 2019 - IPC C09K8/70 C09K8/88 C09K8/92 E21B43/22 E21B43/267

Abstract RU 2700148 C2

FIELD: chemistry.

SUBSTANCE: present invention relates to a liquid composition containing filamentary polymer particles suitable for use in production of oil, condensate or gas from underground deposits. Composition for effecting a subterranean formation containing water, dissolved salts, whisker polymer particles and solid particles, different from whisker polymer particles, which are cylindrical fibres with diameter from 5 nm to 200 nm inclusive, and length from 500 nm to 200 mcm, and said solid particles, other than whisker polymer particles, are proppants. Use of said composition as a hydraulic fracturing fluid. Use of said composition together with an aqueous composition extracted through a well from a subterranean formation as a fluid for producing a hydraulic fracturing fluid, a deflecting composition, a liquid for levelling intake profile, liquid for permeability control, antiseal gravel filter liquid or fluid for acidic hydraulic fracturing.

EFFECT: disclosed is a method for hydraulic fracturing of a subterranean formation using said composition.
