Patent number: 9726157Abstract: The present invention relates to systems and methods of intelligently extracting heat from geothermal reservoirs. One geothermal well system includes at least one injection well extending to a subterranean formation and configured to inject a working fluid into the subterranean formation to generate a heated working fluid. At least one production well extends to the subterranean formation and produces the heated working fluid from the subterranean formation. A production zone defines a plurality of production sub-zones within the subterranean formation and provides fluid communication between the at least one injection well and the at least one production well. Each production sub-zone is selectively accessed in order to extract heated working fluid therefrom and thereby provide a steady supply of heated working fluid to the surface.Type: GrantFiled: May 9, 2012Date of Patent: August 8, 2017Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: Ronald E. Sweatman, Jason L. Pitcher, Norm R. Warpinski, Mark S. Machala, Joel D. Shaw

Patent number: 7314082Abstract: Methods of improving the pressure containment integrity of subterranean well bores are provided. The methods include pumping a fracture sealing composition into the well bore that rapidly converts into a high friction pressure sealing composition which is impermeable, deformable, extremely viscous and does not bond to the faces of fractures. Thereafter, the fracture sealing composition is squeezed into one or more natural fractures or into one or more new fractures formed in the well bore to thereby increase the pressure containment integrity of the well bore. The methods also include the prediction of the expected increase in pressure containment integrity.Type: GrantFiled: May 4, 2006Date of Patent: January 1, 2008Assignee: Halliburton Energy Services, Inc.Inventors: Ronald E. Sweatman, Hong Wang, Wolfgang F. J. Deeg

Patent number: 7191830Abstract: The present invention is an apparatus for relieving annular fluid pressure between nested casing strings. The invention includes a pressure relief collar formed of a cylindrical housing and a set of end connections disposed on opposite sides of the cylindrical housing. The end connections join adjacent sections of casing string of the same diameter. A plurality of equally spaced centralizer blades are secured to the outer surface of the cylindrical housing. Each centralizer blade is equipped with a pressure relief mechanism, which opens the passage of fluid from an outer annulus between adjacent casing strings to an inner annulus between different adjacent casing strings and also prevents backflow of fluid. One or more inlet and outlet filters may also be employed to remove solids and other contaminants from the fluid entering the pressure relief mechanism. The invention also has application as a pressure relief collar for eccentric casing strings.Type: GrantFiled: February 27, 2004Date of Patent: March 20, 2007Assignee: Halliburton Energy Services, Inc.Inventors: Chester S. McVay, Ronald E. Sweatman

Patent number: 6926081Abstract: In accordance with a method of this invention, formation integrity problems are discovered, diagnosed and corrected in successively drilled subterranean well bore intervals. If one or more of well bore fluid outflows, formation fluid inflows or inadequate well bore pressure containment integrity are discovered in a drilled well bore interval, well logs are run and other relevant well bore data is collected in the drilled well bore interval and analyzed to provide a specific treatment using a specific pumpable sealing composition for sealing and increasing the pressure containment integrity of the well bore. Thereafter, the sealing composition is pumped into the drilled well bore interval whereby the well bore interval is sealed or the pressure containment integrity is increased, or both.Type: GrantFiled: February 25, 2002Date of Patent: August 9, 2005Assignee: Halliburton Energy Services, Inc.Inventors: Ronald E.
