Abstract
A method of treating a subterranean formation comprising: providing a proppant; coating the proppant with a geopolymer composition to create a coated proppant; injecting a fracturing fluid into the subterranean formation, wherein the fracturing fluid comprises a base fluid and the coated proppant; and allowing the geopolymer composition to set in the formation to form a geopolymer on the proppant.
Claims16
A method of treating a subterranean formation comprising:
- providing a proppant;
- coating the proppant with a geopolymer composition to create a coated proppant, wherein the proppant is coated with the geopolymer composition at any time during the treating the subterranean formation;
- preparing a fracturing fluid comprising a base fluid and the coated proppant;
- injecting the fracturing fluid into the subterranean formation at a pressure above a fracture gradient of the subterranean formation;
- and
- allowing the geopolymer composition to set in the subterranean formation.

A method comprising:
- injecting into a subterranean formation a substantially proppant-free pad comprising a geopolymer composition at a pressure above a fracture gradient of the subterranean formation;
- generating at least one fracture within the subterranean formation wherein the fracture comprises fracture faces and wherein the fracture faces are partially coated with the geopolymer composition;
- providing a proppant;
- coating a proppant with an additional volume of the geopolymer composition to form a coated proppant;
- mixing the coated proppant with a base fluid to form a fracturing fluid;
- injecting the fracturing fluid into the subterranean formation, wherein the injecting the fracturing fluid comprises injecting the fracturing fluid into the at least one fracture;
- and
- allowing the geopolymer composition to set in the subterranean formation to form a geopolymer on the fracture faces and on the proppant.
