Patent number: 7264052Abstract: Improved methods and compositions for consolidating proppant in subterranean fractures are provided. In certain embodiments, the hardenable resin compositions may be especially suited for consolidating proppant in subterranean fractures having temperatures above about 200° F. Improved methods include providing proppant particles coated with a hardenable resin composition mixed with a gelled liquid fracturing fluid, and introducing the fracturing fluid into a subterranean zone. The fracturing fluid may form one or more fractures in the subterranean zone and deposit the proppant particles coated with the resin composition therein. Thereafter, the hardenable resin composition on the proppant particles is allowed to harden by heat and to consolidate the proppant particles into degradation resistant permeable packs. The hardenable resin composition may include a liquid bisphenol A-epichlorohydrin resin, a 4,4?-diaminodiphenyl sulfone hardening agent, a solvent, a silane coupling agent, and a surfactant.Type: GrantFiled: May 23, 2005Date of Patent: September 4, 2007Assignee: Halliburton Energy Services, Inc.Inventors: Philip D.

Patent number: 6962200Abstract: Improved methods and compositions for coating proppant particles with a hardenable resin composition, suspending the coated proppant particles in a fracturing fluid, and consolidating the proppant particles after being placed in fractures into permeable masses are provided. These methods and compositions are especially suitable for low temperature well, specifically those around the 60° F. to 250° F. ranges. Preferably, a liquid hardenable resin component is mixed with a liquid hardening agent component on-the-fly to form a hardenable resin composition. The hardenable resin composition is coated onto proppant particles on-the-fly that are conveyed from a source thereof to form resin-coated proppant particles in real-time. The resin-coated proppant particles are suspended in the fracturing fluid to be utilized down hole.Type: GrantFiled: April 4, 2003Date of Patent: November 8, 2005Assignee: Halliburton Energy Services, Inc.Inventors: Philip D. Nguyen, Johnny A. Barton, O. Marlene Isenberg

Publication number: 20040211561Abstract: Improved methods and compositions for consolidating proppant in subterranean fractures are provided. In accordance with the methods of the invention, proppant particles coated with a hardenable bisphenol A-epichlorohydrin resin composition are mixed with a gelled liquid fracturing fluid and the fracturing fluid is pumped into a subterranean zone. The fracturing fluid forms one or more fractures in the subterranean zone and deposits the proppant particles coated with the resin composition therein. Thereafter, the hardenable resin composition on the proppant particles is allowed to harden by heat and consolidate the proppant particles into degradation resistant permeable packs. The hardenable bisphenol A-epichlorohydrin resin compositions of the invention are storable for long periods of time before use.Type: ApplicationFiled: March 6, 2003Publication date: October 28, 2004Inventors: Philip D.
