Abstract:
A method of treating a subterranean formation penetrated by a wellbore comprises: introducing into the subterranean formation a treatment fluid comprising a carbonate producing agent, urea, and a cation source; allowing a carbonate precipitate to form, the carbonate precipitate comprising a cation from the cation source and having a water solubility of less than about 0.1 g/100 mL at 25° C. and atmospheric pressure; and reducing or substantially preventing the passage of formation particles from the subterranean formation into the wellbore while allowing passage of formation fluids from the subterranean formation into the wellbore.
