ABSTRACT:
The present invention provides improved methods of stimulating fluid production from an unconsolidated formation penetrated by a well bore while reducing or preventing the migration of formation sands with fluids produced from the formation. The methods basically comprise the steps of placing an explosive in the well bore adjacent to the zone, creating at least one fracture extending from the well bore into the zone, depositing a hardenable resin composition coated proppant in the fracture with some of the resin composition coated proppant also being deposited in the well bore, causing the resin composition to harden and then detonating the explosive to thereby break up and cause the removal of at least a portion of the consolidated proppant in the well bore.
