Methods and compositions useful for subterranean formation treatments,
such as hydraulic fracturing treatments and sand control that include
porous materials. Such porous materials may be selectively configured
porous material particles manufactured and/or treated with selected
glazing materials, coating materials and/or penetrating materials to have
desired strength and/or apparent density to fit particular downhole
conditions for well treating such as hydraulic fracturing treatments and
sand control treatments. Porous materials may also be employed in
selected combinations to optimize fracture or sand control performance,
and/or may be employed as relatively lightweight materials in liquid
carbon dioxide-based well treatment systems.
