ABSTRACT:
The present invention provides methods of stimulating fluid production while preventing the migration of sand with produced fluids from an unconsolidated subterranean formation penetrated by a well bore. The methods basically comprise the steps of creating one or more fractures in the formation, injecting a hardenable resin composition into a portion of the formation through which the fractures extend whereby the portion of the formation is consolidated into a hard permeable mass and depositing proppant in the fractures to maintain the fractures open.
