Abstract
A method for consolidating a proppant in a formation comprises injecting in the formation a composition comprising an enzyme and a substrate. The enzyme and the substrate may react, optionally in the presence of a precipitating compound, to form a solid precipitate on the surface of proppant particles to consolidate the proppant in situ, e.g., in one or more fractures of the formation.
