Abstract

The present invention provides methods of stimulating fluid production from an unconsolidated formation penetrated by a wellbore while preventing the migration of formation sand with fluids produced from the formation. The methods basically comprise the steps of injecting a liquid composition into a portion of the formation surrounding the wellbore which converts into a gel-like substance and plugs the permeability of the injected portion of the formation, but allows the injected portion to remain flexible and resist breakdown due to pressure cycling therein, creating at least one fracture in the formation extending from the wellbore through the plugged portion of the formation into an unplugged portion thereof and depositing hardenable resin composition coated proppant in the fracture and causing the resin composition to harden and consolidate the proppant into a hard permeable mass.
