Unconsolidated formation stimulation with sand filtration

摘要

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.
