Patent number: 7299862Abstract: When latent heat is transferred between the two airflows flowing along the respective sides of each partition member, not only a layer of moisture absorbent but also a layer of flame retardant lies in the direction of transfer of the moisture. Thus, even if the moisture is absorbed by the layer of moisture absorbent, the layer of flame retardant resists the moisture transfer so that the amount of transfer of the moisture decreases in that part with a drop in the moisture permeability of the partition member. To solve the problem, there is provided a total heat exchanging element comprising partition members and spacing members having moisture permeable portions provided with moisture permeability and flame resisting portions provided with flame retardancy, the both portions not overlapping with each other within each single member.Type: GrantFiled: July 15, 2004Date of Patent: November 27, 2007Assignees: Mitsubishi Denki Kabushiki Kaisha, Mitsubishi Paper Mills LimitedInventors: Masaru Takada, Hidemoto Arai, Youichi Sugiyama, Hisao Yokoya, Kenzo Takahashi, Junji Harada, Masayuki Tsubaki

Patent number: 7299863Abstract: Disclosed is a louver fin type heat exchanger positioned upright at a certain angle with respect to the ground, wherein lower end portions of louver fins close to the ground are bent toward lower end portions of adjacent louver fins, such that the air passage at the lower end portion close to the ground has cross-section areas that are wide at certain portions and are narrow at other portions thereof. Accordingly, moisture congregates only at a portion where the cross-section of the air passage is great, so that the external air smoothly passes into or out the heat exchanger through the air passage where the moisture congregation does not occur, minimizing the pressure drop, and efficiency in heat exchange of the heat exchanger can be thusly improved.Type: GrantFiled: December 19, 2005Date of Patent: November 27, 2007Assignee: Korea Institute of Science and TechnologyInventors: Dae-Young Lee, Hyun-Seon Choo

Patent number: 7299876Abstract: In one embodiment, provided is a method of fracturing a portion of a subterranean formation that comprises providing a viscosified treatment fluid comprising a single salt aqueous fluid having a density of greater than 9 pounds per gallon and a crosslinked viscosifying agent, and contacting the portion of the subterranean formation with a viscosified treatment fluid so as to create or enhance one or more fractures therein, wherein the viscosified treatment fluid is introduced into a well bore that penetrates the portion of the subterranean formation to be fractured at a surface pressure of less than about 25,000 pounds per square inch. In other embodiments, provided are methods of frac packing a subterranean formation and methods of reducing a surface pressure needed to create one or more fractures in a portion of a subterranean formation.Type: GrantFiled: March 19, 2007Date of Patent: November 27, 2007Assignee: Halliburton Energy Services, Inc.Inventors: Paul D. Lord, Rodney B. Waltman, David W. Ritter, Sanjay Vitthal

Patent number: 7299877Abstract: The invention provides a fluid for use in a subterranean formation penetrated by a wellbore, the fluid comprising: (a) water; (b) an orthoester; and (c) a surfactant comprising a tertiary alkyl amine ethoxylate generally represented by the following formula: wherein R is an alkyl group or aryl group, and wherein X and Y are each independently at least one. The invention also provides a method of fracturing a subterranean formation, comprising the step of forming a foamed fracturing fluid comprising water; an orthoester; a surfactant comprising a tertiary alkyl amine ethoxylate generally represented by the formula above; and a gas. The method also provides the step of introducing the foamed fracturing fluid into a subterranean formation at a pressure sufficient to create a fracture in the subterranean formation.Type: GrantFiled: August 9, 2005Date of Patent: November 27, 2007Assignee: Halliburton Energy Services, Inc.Inventors: Thomas D. Welton, Bradley L. Todd, David McMechan

Patent number: 7299878Abstract: A high pressure multiple branch wellbore junction. A wellbore junction system includes a wellbore junction with at least three bores extending therethrough. Exits of the three bores are axially spaced apart. At least two deflectors are formed on the wellbore junction. The deflectors are axially spaced apart, and each of the deflectors is aligned with a respective lateral exit of the bores.Type: GrantFiled: September 24, 2003Date of Patent: November 27, 2007Assignee: Halliburton Energy Services, Inc.Inventor: David J. Steele

Patent number: 7299880Abstract: Methods and apparatus are provided for reducing surge pressure while running casing into a wellbore. The apparatus includes a running string for running casing having a diverter tool therein. The diverter tool has one or more bypass ports between its upper and lower end which are normally closed. In operation, the diverter tool is automatically cycled between the open and closed positions of the bypass ports during a casing running operation. A pressure event inside the diverter tool deactivates the cyclic opening and closing function of the bypass port.Type: GrantFiled: June 27, 2005Date of Patent: November 27, 2007Assignee: Weatherford/Lamb, Inc.Inventors: Michael Logiudice, James G. Martens

Patent number: 7299882Abstract: The present disclosure addressed apparatus and methods for forming an annular isolator in a borehole after installation of production tubing. Annular seal means are carried in or on production tubing as it is run into a borehole. In conjunction with expansion of the tubing, the seal is deployed to form an annular isolator. An inflatable element carried on the tubing may be inflated with a fluid carried in the tubing and forced into the inflatable element during expansion of the tubing. Reactive chemicals may be carried in the tubing and injected into the annulus to react with each other and ambient fluids to increase in volume and harden into an annular seal. An elastomeric sleeve, ring or band carried on the tubing may be expanded into contact with a borehole wall and may have its radial dimension increased in conjunction with tubing expansion to form an annular isolator.Type: GrantFiled: January 19, 2007Date of Patent: November 27, 2007Assignee: Halliburton Energy Services, Inc.Inventors: Michael M. Brezinski, Gregory B. Chitwood, Gary P. Funkhouser, John C. Gano, Jody R. McGlothen, Alex Procyk, Thomas W. Ray, Robert S. Taylor, Bradley L. Todd, Cynthia Tuckness

Patent number: 7299884Abstract: Measurements are made continuously with a seismic while drilling (SWD) system and the measured data are stored in a working memory of a downhole processor along with quality control (QC) measurements. The QC data are analyzed and based on the analysis, portions of the data in working memory are recorded in permanent memory for retrieval. Alternatively, QC measurements are made substantially continuously predictions are made when data quality for SWD measurements are likely to be good. Recording of SWD data are then started based on the prediction.Type: GrantFiled: March 17, 2004Date of Patent: November 27, 2007Assignee: Baker Hughes IncorporatedInventor: Holger Mathiszik
