Abstract
A method of inducing tip screenout during a frac-packing treatment comprising injecting a proppant slurry into a subterranean formation, wherein the proppant slurry comprises a proppant material, a fracturing fluid, and degradable particulates and wherein the degradable particulates physically interact with themselves and with the proppant material to aid in inducing tip screenout. A method of preparing a proppant slurry for inducing tip screenout during a frac-packing treatment, comprising blending a proppant material with a fracturing fluid and degradable particulates wherein the degradable particulates physically interact with themselves and with the proppant material to aid in inducing tip screenout. A proppant slurry for inducing tip screenout during a frac-packing treatment, comprising a proppant material, a fracturing fluid, and degradable particulates wherein the degradable particulates physically interact with themselves and with the proppant material to aid in inducing tip screenout.
