ABSTRACT:
Methods of gravel packing comprising providing a gravel packing fluid comprising a base fluid and substantially hydrated cement particulates, introducing the gravel packing fluid into a subterranean formation, and depositing at least a portion of the substantially hydrated cement particulates in the subterranean formation to form a gravel pack. Gravel packing fluids that comprise a base fluid, and gravel comprising substantially hydrated cement particulates. Methods of gravel packing and fracturing a subterranean formation comprising fracturing the subterranean formation so as to create or enhance one or more fractures in the subterranean formation; introducing a fluid comprising a base fluid and substantially hydrated cement particulates through a well bore into the one or more fractures; and depositing at least a portion of the substantially hydrated cement particulates in the one or more fractures in the subterranean formation and in the well bore to form a gravel pack.
