62 CEMENT COMPOSITIONS FOR HIGH TEMPERATURE APPLICATIONS EP03702647.3 2003-02-14 EP1478606A1 2004-11-24 BARLET-GOUEDARD, Véronique; DANICAN, Samuel; NELSON, Erik,Schlumberger; GOFFE, Bruno; CAMBUS, Chrystel
In a process to design high temperature cement sluries, the temperature stable phases (anorthite, wairakite) are selected; aluminum modifiers and silica oxides are added to the dry cement so that the elemental composition of the blend corresponds to the phases selected; the control of the particle size distribution and the relative amount of those minerals allow their addition at high concentration while leaving the slurry easily mixable and pumpable; and the kinetics of the targeted phases formation is then controlled by adjusting the crystallinity and the particles sizes of the different solids.

Disclosed is a method and apparatus for spray application of a monolithic refractory material, designed to add water to a powder material and knead the powder material during feeding. In the method and apparatus, a primary water injector 7 is arranged in a feed hose 5 extending from a spray-material supply device 1 to a distal spray nozzle 4, and a secondary water injector 8 is arranged in the feed hose at a position just before the distal spray nozzle 4. The primary water injector 7 is arranged on an upstream side of the secondary water injector 8 with a given distance therebetween. 10 to 50 mass %, preferably 15 to 40 mass %, of application water on the basis of the total application water required for the spray application is added from the primary water injector together with compression air in the form of water particles having an average particle size of 100 μm or less, to evenly wet a spray material during feeding to the extent capable of preventing the spray material from being slurried. Then, the remaining application water is injected from the secondary water injector together with compression air. The spray application method and apparatus of the present invention can achieve a high kneading effect by a low amount of application water while improving operational efficiency.
75 Cement compositions useful in oil and gas wells US11598382 2006-11-13 US07442249B2 2008-10-28 T. Dan Mueller
Cement compositions containing low reactivity materials are disclosed. The compositions are useful in conditions involving high temperatures, high pressures, and tectonic forces such as oil and gas wells. The cement compositions display increased compressive strength, flexural strength, and tensile strength. Fractures appear to occur in a non-linear fashion between the Interfacial Transition Zone (ITZ) of the particles, rather than in a straight line such as those observed in conventional cement materials.

78 Carbon foam with improved graphitizability US11321714 2005-12-29 US20070154381A1 2007-07-05 Douglas Miller; Irwin Lewis; Richard Shao; Terrence Pirro
A carbon foam material with improved graphitizability is formed by including a graphitization promoting additive into the carbon foam. The graphitization promoting additive greatly improves the graphitic structure of the carbon foam resulting in a carbon foam with much greater thermal and electrical conductivities. This inventive foam may be created by introducing the graphitization promoting additive during the catalysis of a phenol-aldehyde mixture to a form phenolic resin or during the conversion of the phenolic resin to a phenolic foam. Alternatively, the graphitization promoting additive can be fixed onto a preformed carbon foam.
