Abstract
A method of treating a subterranean formation comprising hydraulically fracturing the formation and filling the fractures with a self-consolidating proppant. The proppant is consolidated and the formation then acidized to produce channels of increased conductivity adjacent the consolidated proppant.
Claims4
A method for treating a subterranean formation comprising:
- hydraulically fracturing said formation to create fractures therein;
- filling said fractures with self-consolidating resin coated particles;
- curing said resin coated particles to form a cohesive permeable matrix within said fractures;
- and
- acidizing said formation so as to produce channels of increased conductivity adjacent said matrix.

A method for treating a subterranean carbonate formation comprising:
- hydraulically fracturing said formation to create fractures therein;
- filling said fractures with self-consolidating resin coated particles comprised of high strength centers, a coupling agent chemically bound to said centers, a novalac resin coated over said centers and chemically bound to the coupling agent, and a cross-linking agent;
- curing said resin coated particles to form a cohesive permeable matrix within said fracture;
- and
- acidizing said formation so as to produce channels of increased conductivity adjacent said matrix.
