FIELD: chemistry. SUBSTANCE: present invention discloses modified proppants and methods for production thereof. Modified proppant, which comprises a proppant particle substrate and hydrogel coating, wherein said coating includes a hydrogel-forming polymer, has thickness from 0.01 % to 20 % of average diameter of said substrate, hydrogel-forming polymer swells upon contact with water-based fluid to form a hydrogel coating around proppant particle substrate, after hydration and swelling, said… CONTINUE READING
