COATING AND/OR TREATING HYDRAULIC FRACTURING PROPPANTS TO IMPROVE WETTABILITY, PROPPANT LUBRICATION, AND/OR TO REDUCE DAMAGE BY FRACTURING FLUIDS AND RESERVOIR FLUIDS

摘要

Surface modified oil and gas well hydraulic fracturing proppants for improving wettability, altering chemical reactivity, altering surface topography, imparting lubrictiy or controlling relative permeability to flow of fluids of such proppants. The use and preparation of such coated proppants in hydraulic fracturing of subterranean formations is also described.
