Method of Treating Ultra-Low Permeable Subterranean Formations Using Proppant Particulates Coated with Degradable Material

A method of treating an ultra-low permeability subterranean formation having a fracture complexity comprising interconnected fractures comprising:

• providing a fracturing fluid comprising a base fluid, coated proppant, and degradable particulates,
• wherein the coated proppant comprise proppant coated with a degradable material;
• introducing the fracturing fluid into the ultra-low permeability subterranean formation at a rate and pressure above a fracture gradient of the ultra-low permeability subterranean formation;
• placing the coated proppant and the degradable particulates into at least one fracture of the interconnected fractures so as to form a temporarily impermeable proppant pack comprising the coated proppant and the degradable particulates therein and reduce or prevent the extension of the fracture;
• reducing the pressure below the fracture gradient;
• and
• degrading the degradable particulates and the degradable material coating the coated proppant so as to cause the temporarily impermeable proppant pack to become a permeable proppant pack.

A method of treating an ultra-low permeability subterranean formation having a fracture complexity comprising interconnected fractures comprising:

• providing a fracturing fluid comprising a base fluid, coated proppant, and coated degradable particulates,
• wherein the coated proppant comprise proppant coated with a first degradable material, and
• wherein the coated degradable particulates comprise degradable particulates coated second degradable material;
• introducing the fracturing fluid into the ultra-low permeability subterranean formation at a rate and pressure above a fracture gradient of the ultra-low permeability subterranean formation;
• placing the coated proppant and the coated degradable particulates into at least one fracture of the interconnected fractures so as to form a temporarily impermeable proppant pack comprising the coated proppant and the coated degradable particulates therein and reduce or prevent the extension of the fracture;
• reducing the pressure below the fracture gradient;
• and
• degrading the first and second degradable material coating the coated proppant and the coated degradable particulates, so as to cause the temporarily impermeable proppant pack to become a permeable proppant pack.
