HEAVY OIL AS FRACTURING FLUID TO INCREASE HYDRAULIC FRACTURING EFFICIENCY

摘要

Compositions, systems, and methods for hydraulically fracturing a hydrocarbon-bearing formation, a method including injecting into the hydrocarbon-bearing formation under increased pressure a heavy oil fracturing fluid; allowing the heavy oil fracturing fluid to remain in situ for a period of time suitable to create fractures in the hydrocarbon-bearing reservoir, the heavy oil fracturing fluid operable to undergo an at least about 70% viscosity decrease in situ; and flowing back the heavy oil fracturing fluid to the surface without damaging the hydrocarbon-bearing formation or reducing production of hydrocarbons from the hydrocarbon-bearing formation.
