Patent number: 9222014Abstract: Method of treating a subterranean formation comprising providing a consolidation fluid, introducing the resin consolidation fluid into a subterranean formation comprising unconsolidated particulates; and, curing the resin to at least partially consolidate the unconsolidated particulates. The consolidation fluid comprises a resin in emulsified form with an aqueous external phase and an organic internal phase wherein the emulsified resin does not comprise a hardening agent and an aqueous base fluid that further comprises a hardening agent. The consolidation fluid may further comprise an emulsifying agent.Type: GrantFiled: April 27, 2012Date of Patent: December 29, 2015Assignee: Halliburton Energy Services, Inc.Inventors: Richard D. Rickman, Ronald G. Dusterhoft, Philip D. Nguyen, Thomas D. Welton, Jimmie D. Weaver, Mike W. Sanders, Harvey J. Fitzpatrick

Patent number: 9194222Abstract: Systems and methods for improved propped fracture geometry for high permeability reservoirs are provided. In one embodiment, a method of determining a pad volume and proppant volume for fracturing a subterranean formation is provided comprising selecting a proppant volume for placement in a fracture to be created in a subterranean formation; determining a desired fracture geometry for the fracture; calculating a pad volume sufficient to create the desired fracture geometry in the subterranean formation at a lower fluid efficiency value; calculating a fracture length that would result from injecting the pad volume into the subterranean formation at an upper fluid efficiency value; calculating a fracture width that corresponds to the calculated fracture length; and calculating a proppant volume sufficient to fill a fracture having the calculated length and width.Type: GrantFiled: April 19, 2011Date of Patent: November 24, 2015Assignee: Halliburton Energy Services, Inc.Inventors: Brad A. Clarkson, Harvey J. Fitzpatrick

Patent number: 8561699Abstract: A well screen assembly with enhanced well treatment capabilities. A well screen assembly can include a well treatment substance secured to the well screen assembly, and at least one reactive component of a well treatment stimulant. The reactive component can also be secured to the well screen assembly. A method of treating a well can include expanding a well screen assembly outward in a wellbore of the well, thereby decreasing a distance between a well treatment substance and a wall of the wellbore. Another method of treating a well can include contacting multiple reactive components of a well treatment stimulant with each other in the well, thereby dispersing a well treatment substance about a well screen assembly.Type: GrantFiled: December 13, 2010Date of Patent: October 22, 2013Assignee: Halliburton Energy Services, Inc.Inventor: Harvey J. Fitzpatrick, Jr.

Patent number: 8443885Abstract: Methods are provided that include a method comprising providing a consolidating agent emulsion composition comprising an aqueous fluid, an emulsifying agent, and a consolidating agent; and introducing the consolidating agent emulsion composition into at least a portion of a subterranean formation. In some embodiments, the consolidating agent emulsion composition may be introduced into at least a portion of a propped fracture that comprises proppant particulates and allowed to at least partially consolidate at least a portion of the propped fracture. In some embodiments, the consolidating agent emulsion composition comprises a resin composition. Additional methods are also provided.Type: GrantFiled: August 30, 2007Date of Patent: May 21, 2013Assignee: Halliburton Energy Services, Inc.Inventors: Richard D. Rickman, Ronald G. Dusterhoft, Philip D. Nguyen, Thomas D. Welton, Jimmie D. Weaver, Mike W. Sanders, Harvey J. Fitzpatrick

Publication number: 20130014951Abstract: The present disclosure relates to applying treatment fluid to a rock matrix in a subterranean formation. An injection fluid is received in a wellbore in a subterranean formation. The subterranean formation includes a rock matrix about the wellbore. Shear bands are induced in the rock matrix by communicating the injection fluid from the wellbore into the rock matrix. A chemical treatment fluid is communicated through the shear bands into the matrix. The chemical treatment is conducted from the wellbore primarily by a portion of the rock matrix that forms a wall of the wellbore, primarily by a subset of the shear bands that intersect the wall of the wellbore, or primarily by a combination of them. In some instances, the shear bands may improve uniformity or efficiency of the chemical treatment.Type: ApplicationFiled: July 15, 2011Publication date: January 17, 2013Applicant: Halliburton Energy Services, Inc.Inventor: Harvey J.
