| titleOfInvention | Self-suspending proppant for liquid cracking |
| abstract | The present invention is directed to a modified proppant comprising proppant particles and a hydrogel coating wherein the hydrogel coating is localized on the surface of the proppant particles to produce a modified proppant. The proppant particles can be solids such as sand, bauxite, sintered bauxite, ceramic, or low density proppants. Alternatively or additionally, the proppant particles comprise a resin coated substrate. Optionally, the modified proppant further includes an adhesion promoter that attaches the hydrogel coating to the resin coated substrate as appropriate. The hydrogel coating preferably comprises a water swellable polymer. Hydrogel coatings can be produced from water soluble polymers. The preferred weight average molecular weight of the polymer is about 1 million g/mol, preferably about 5 million g/mol. |
