ABSTRACT:
Methods and compositions for preventing fracture proppant particle flowback from subterranean zones penetrated by well bores are provided. The methods basically comprise the following steps. One or more fractures are formed in a subterranean zone and proppant particles coated with a curable liquid composition for consolidating the proppant particles into resilient permeable masses are deposited in the fractures. The curable liquid composition is a mixture of a tackifying compound liquid and a curable resin. After the coated proppant particles have been deposited, the curable liquid composition is allowed to cure.
