Claim:
1. A method comprising: introducing a fracturing fluid containing proppant into a subterranean formation having formation particulates therein at a pressure sufficient to create or enhance at least one fracture having a proppant pack therein wherein at least a portion of the proppant has a weight mean particle size between 20 times and 50 times the weight mean particle size of the formation particulates; providing a treatment fluid comprising a carrier fluid and a curable compound according to the general formula (1): wherein L is a carbamate linkage, R is a cyclic or acyclic alkyl or alkenyl group of 1 to 20 carbon atoms, and n=1 or 2, wherein the compound is not cured at room temperature, standard pressure or neutral pH; introducing the treatment fluid into the at least one fracture wherein introducing the treatment fluid into the at least one fracture is performed at matrix flow rates; and exposing the treatment fluid to at least one condition selected from the group consisting of: a temperature of greater than about 120° F., a pressure of greater than 1 atmosphere, acidic conditions, or a combination thereof, thereby cleaving the carbamate linkage of the curable compound and activating the amines thereof in the at least one fracture in the subterranean formation, wherein the activated amines react to form epoxides that crosslink and form a cured proppant pack in the at least one fracture in the subterranean formation.
