METHOD FOR HYDRAULIC RUPTURE OF THE FORMULATING USING SUSPENSIONS OF SUPER-LIGHT PROPANET AND GAS FLOWS

摘要

1. The method of hydraulic fracturing of an underground formation, in which the proppant phase is injected into the underground formation, wherein the proppant phase contains a fine-structure foam containing (i) a high-viscosity water-based liquid having an ultralight (SL) proppant suspended in an aqueous liquid base with increased viscosity; and (ii) a gaseous medium, wherein the gaseous medium comprises at least about 85% by volume of the combination of the gaseous medium and the water-based liquid in the fine structure foam, wherein the bubble diameter of at least 70% of the volume of the fine structure gas gas is less than or equal to 0.18 mm, while the proppant phase is injected into the subterranean formation under a pressure sufficient to form or expand a crack. 2. A method according to claim 1, wherein the diameter of the bubbles of the fine-structure foam is from about 0.01 to about 0.10 mm. A method according to claim 1, wherein the diameter of the bubbles in at least 80% of the gas volume of the fine-structure foam is less than or equal to 0.18 mm. The method according to claim 3, wherein the diameter of the bubbles of the fine-structure foam is from about 0.01 to about 0.10 mm. The method of claim 3, wherein the diameter of the bubbles in at least 90% of the gas volume of the fine-structure foam is less than or equal to 0.18 mm. The method according to claim 5, wherein the diameter of the bubbles of the fine-structure foam is from about 0.01 to about 0.10 mm. A method according to claim 1, wherein the amount of proppant suspended in a water-based fluid with increased viscosity is an amount sufficient to form a partial proppant monolayer in the fracture.
