Patent number: 8127846Abstract: A method and system for cementing and perforating a wellbore in a single step by coupling a perforating gun with a wiper plug. The method includes injecting cement in a wellbore having casing therein and an annulus between the casing and wellbore. A wiper plug is dropped on the cement having a perforating gun attached to the wiper plug. The plug is forced downward pulling the perforating gun along. The downward motion of the plug in turn pushes the cement out the bottom end of the casing and into the annulus. The cement in the annulus is allowed to set and the perforating gun is activated.Type: GrantFiled: February 27, 2009Date of Patent: March 6, 2012Assignee: Baker Hughes IncorporatedInventors: Freeman L. Hill, Randy L. Evans, John H. Clark, Mark L. Sloan, William D. Myers, Jr., Joseph Gregory Barolak, George Patton

Patent number: 7795864Abstract: A casing inspection device with magnets and a multi-component flux sensors. The multicomponent sensor enables better definition of the size of defects, particularly in the azimuthal direction.Type: GrantFiled: March 11, 2005Date of Patent: September 14, 2010Assignee: Baker Hughes IncorporatedInventors: Joseph Gregory Barolak, Douglas W. Spencer, Jerry E. Miller, Bruce I. Girrell, Jason A. Lynch, Chris J. Walter

Patent number: 7773454Abstract: A method and apparatus useful to determine the integrity of a cement bond log disposed in the annular space between a casing and a wellbore. The method and apparatus produce a transversely polarized shear wave and emit the wave through the casing and into the wellbore. The transversely polarized shear wave attenuates upon passage through the cement bond log. The integrity of the cement bond log can be determined through an analysis and evaluation of the attenuation results.Type: GrantFiled: February 22, 2006Date of Patent: August 10, 2010Assignee: Baker Hughes IncorporatedInventors: Joseph Gregory Barolak, Douglas J Patterson, Alexei Bolshakov, Vladimir Dubinsky, Xiao Ming Tang

Patent number: 7757769Abstract: A modular wellbore treatment system having a reservoir for holding wellbore/reservoir treatment material, a pump for pressurizing and delivering the wellbore/reservoir treatment fluid, and a sealing section for creating a localized pressurized zone proximate to a region of a formation to be treated. The wellbore treatment fluid includes permeability modifiers, gel, acids, stimulation fluids, epoxy type substances, void fillers, gravel pack fixing compounds, brine, reactive fluids to water, oil, and gas, and alcohol.Type: GrantFiled: October 4, 2007Date of Patent: July 20, 2010Assignee: Baker Hughes IncorporatedInventors: Freeman L. Hill, Gary J. Cresswell, Joseph Gregory Barolak, Randy L. Evans

Patent number: 7681450Abstract: A method useful for evaluating the presence and/or the quality of the cement bond of a downhole tubular. The method involves measuring radial resonance modes of the tubular, and comparing those measured values to the unbound tubular resonant values of a calibration ring. For a well bonded tubular, the measured radial resonance should be greater than that of the unbound tubular calibration ring. In regions where a fluid, such as water surrounds the outside of the tubular, or the cement is otherwise not bonded to the outer surface of the tubular, the measured response should be less than the calibrated response. The calibration ring should have the same diameter, wall thickness, and be made of the same material as the tubular.Type: GrantFiled: December 6, 2006Date of Patent: March 23, 2010Assignee: Baker Hughes IncorporatedInventors: Alexei Bolshakov, Vladimir Dubinsky, Xiao Ming Tang, Douglas J. Patterson, Dimitri Donskoy, Joseph Gregory Barolak

Patent number: 7660197Abstract: An apparatus for evaluating a tubular in a borehole of includes at least two electromagnetic acoustic transducers. The transducers are configured to generate and receive first and second acoustic waves in the tubular. A difference in velocity of the two acoustic waves is indicative of a stress field in the tubular.Type: GrantFiled: January 11, 2007Date of Patent: February 9, 2010Assignee: Baker Hughes IncorporatedInventor: Joseph Gregory Barolak
