EMULSION COMPOSITION FOR HYDRAULIC FRACTURING FORMATION Russian patent published in 1997 - IPC

Abstract RU 2097547 C1

FIELD: oil and gas production. SUBSTANCE: invention is applicable when hydraulically fracturing formation, killing and preserving well, performing perforation operations, and limiting water flood into oil and gas wells. Friction loss-reducing emulsion composition contains (in wt %): hydrocarbon phase, 5-25; oil-soluble emulsifier, 0.3-5.0; condensed sulfite-alcohol brew or lignosulfonate, 0.1-1.0; solution of water-soluble polymer prepared with soft or mineralized water containing 0.3-1.0 wt % polyacrylamide or carboxymethylcellulose, 5- 25; soft or mineralized water, the balance. Composition preserves high viscosity needed for fracturing formation, sand retaining capability, low filtration, and controlled destruction. EFFECT: reduced friction- linked loss of pressure in pipes. 3 tbl
