1. A method for consolidating a carbonate-based formation, comprising:
injecting a fracture within the carbonate-based formation with a composition, the composition comprising:
a zinc metalloenzyme;
ground calcium carbonate; and
a solvent comprising water and another solvent, wherein the solvent has a viscosity in a range of 35 to 70 centipoise;
mechanically enhancing the carbonate-based formation with the composition.
