Patent number: 7735578Abstract: A perforating gun having a charge case with a boss element partially circumscribing Optionally the pair of bosses may be included that are substantially symmetric about the axis of the charge case. Forming a shaped charge with such a charge case allows for gun strips to be formed with increased web material between adjacent shape charges in the gun strips. The increased web material provides for a more structurally sound gun tube, especially when dealing with high density charges. Notches may be provided in the gun tube on the outer radius of the holes formed to receive the shape charges, the notches are to be aligned with the bosses on the outer periphery of the shaped charge case. This also may orient the charge cases so they are pre-aligned for ready connection to an associated detonation cord.Type: GrantFiled: February 7, 2008Date of Patent: June 15, 2010Assignee: Baker Hughes IncorporatedInventors: John D. Loehr, Patrick R. Markwardt

Patent number: 7581498Abstract: A shaped charge liner formed by injection molding, where the liner components include powdered metal and organic binder. The liner components are blended then processed within an injection molding device and urged from the molding device into a mold where a liner shape is formed. The liner shape is debinded, both mechanically and chemically. Mechanical debinding involves heating and chemical debinding comprises treating the liner shape with a solution to dissolve and remove the binder components. The process of forming the shaped charge liner does not include sintering. The present process can also use “green products” formed by the injection molding device that are not debinded. A shaped charge case can also be formed using the present method. The added step of sintering can be applied to the process of forming the shaped charge case.Type: GrantFiled: August 23, 2005Date of Patent: September 1, 2009Assignee: Baker Hughes IncorporatedInventors: Avigdor Hetz, Clarence W. Wendt, John D. Loehr

Patent number: 7523640Abstract: A method of determining properties of a formation fluid based on measurements of fluid sound speed, a measurement of fluid density, or both. The properties include compressibility, thermal conductivity, and gas oil ratio. The compressibility of a fluid is equal to the reciprocal of the product of the sound speed squared and fluid density. The density and the sound speed can be measured acoustically. The method further includes a manner of processing data including applying the Savitzky-Golay method and utilizing a variable thresholding technique.Type: GrantFiled: August 1, 2005Date of Patent: April 28, 2009Assignee: Baker Hughes IncorporatedInventors: Rocco DiFoggio, Weimin Yao

Patent number: 7525872Abstract: 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 26, 2004Date of Patent: April 28, 2009Assignee: Baker Hughes IncorporatedInventors: Xiao-Ming Tang, Alexei Bolshakov, Tsili Wang, Douglas Patterson

Method for processing acoustic reflections in array data to image near-borehole geological structure
Patent number: 7492664Abstract: A method and apparatus for enhancing the moveout between a direct wave and a reflected wave. The method involves transmitting imaging signals into a body to be imaged and receiving the resulting signals propagated from the signal source. The step of receiving the propagated signals includes selectively adjusting the distance between the signal source and the signal receivers between successive signals. The method further comprises separating the reflected signals from the total received signals and enhanced stacking of the measured reflected signals.Type: GrantFiled: January 27, 2006Date of Patent: February 17, 2009Assignee: Baker Hughes IncorporatedInventors: Xiao Ming Tang, Yibing Zheng, Douglas J Patterson -
Patent number: 7405904Abstract: A device streamlines air flow inside a hard disk drive with a stationary afterbody that is located adjacent to each of the disks. A diverter portion of the device enhances the volumetric flow of air through a diffuser and a contraction. The overall function of the device effectively expands the air flow so that the speed of the air flow gradually decreases while pressure increases. This design reduces losses in system momentum due to sudden expansion of the air in the drive. In addition, air flow moving toward the disk pack may be contracted to allow efficient energy conversion from pressure energy to kinetic energy prior to merging of the bypass air flow with the air flow among the disks.Type: GrantFiled: February 26, 2007Date of Patent: July 29, 2008Assignee: Hitachi Global Storage Technologies Netherlands BVInventors: Andre Sirilutporn Chan, Ferdinand Hendriks, Michael Robert Hatchett, Jr-Yi Shen

Patent number: 7252702Abstract: A method of hydrogen recovery in refineries and petrochemical operations in which some or all of the feed streams for separate PSA units are combined and utilized as feed for a single PSA unit, and in which some or all of steam reformer product and refinery offgas streams being used as feed streams for separate PSA units are combined and utilized as feed for a single PSA unit. Total hydrogen recovery is increased by maximizing hydrogen recovery from refinery offgases. The load on the steam reformer is reduced by lowering the reformer feed stream. Refinery fuel gas consumption is reduced in the steam reformer furnace. The amount of a PSA feed stream being burned as fuel or sent to flare is reduced. The load on the PSA unit receiving feed from refinery offgases is reduced. The hydrocarbon content and heating value of the tail gas from the PSA unit fed by the steam reformer product stream is enriched.Type: GrantFiled: July 25, 2003Date of Patent: August 7, 2007Assignee: Saudi Arabian Oil CompanyInventor: Ibrahim M. Al-Babtain

Patent number: 7108069Abstract: A system, method, and software for optimizing the commingling of well fluids from a plurality of producing subsea wells. The mixing temperature and water content in each header of a collection manifold are calculated for each subsea well and header combinations, responsive to data from sensors at the collection manifold. Combinations with conditions outside operational limits are then discarded. Remaining combinations are ranked based on predetermined optimization criteria. The ranked combinations are provided for the operator for optimizing flow properties and well fluid production. The calculations can restart with new, real-time sensed values from the subsea collection manifold.Type: GrantFiled: April 23, 2004Date of Patent: September 19, 2006Assignee: Offshore Systems, Inc.Inventors: Rune Killie, John Allen
