Abstract

A method of using a slurry-like fracturing fluid for hydraulic fracturing in an unconventional reservoir: injecting the slurry-like fracturing fluid into the unconventional reservoir, the slurry-like fracturing fluid comprises a particulate portion and a slurry water, the particulate portion comprises a solid acid component, injecting the slurry-like fracturing fluid is operable to generate a network of fractures, the slurry-like fracturing fluid is operable to reduce a reservoir temperature from a resting reservoir temperature, permitting the slurry-like fracturing fluid to cure into a permeable bed, allowing the reservoir temperature to return to the resting reservoir temperature to trigger the hydrolysis of the solid acid, hydrolyzing the solid acid to produce a liquid acid, and stimulating the network of fractures with the liquid acid to increase permeability of the permeable bed in the network of fractures in the unconventional reservoir, the increased permeability operable to create a sweet spot.
