Method For Fracturing Coal Seams
US Patent:
4995463, Feb 26, 1991
Filed:
Jun 4, 1990
Appl. No.:
7/532830
Inventors:
Robert C. Kramm - Plano TX

Abstract:
Method for fracturing coal seams to improve the production (e. g. methane and/or water) therefrom. A water-based fracturing fluid is injected into the coal seam under pressure wherein the fracturing fluid contains both a wetting agent and a dispersant. The wetting agent contacts the fines which are formed during the fracturing of the coal and converts them from "hydrophobic" to "hydrophilic" while the dispersant serves to disperse and suspend the fines within the fracturing fluid. This prevents early screen-out of the fines from the fracturing fluid which allows the fluid to propagate fractures of longer lengths into a coal seam before the fines settle out to block further flow through a fracture.
