  • Patent number: 9488042
    Abstract: A method of increasing a stimulated reservoir volume in a wellbore in a gas-containing formation includes the steps of mixing an exothermic reaction component to achieve a pre-selected solution pH, the exothermic reaction component is operable to react at a wellbore temperature to generate a pressure pulse, mixing the exothermic reaction component with a viscous fluid component operable to fracture the gas-containing formation to create fractures, and a proppant component, the proppant component carried to the fractures by the viscous fluid, the proppant component comprises a proppant operable to hold open the fractures, to form a fracturing fluid, injecting the fracturing fluid into the wellbore in the gas-containing formation to create fractures, and generating the pressure pulse when the exothermic reaction component reaches the wellbore temperature, the pressure pulse operable to create auxiliary fractures, wherein the auxiliary fractures create a fracture network, the fracture network increases the stimu

  • Patent number: 9366125
    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.
