Abstract:
A method, a map and an article of manufacture for the exploration of hydrocarbons. In one embodiment of the invention, the method comprises the steps of: accessing 3D seismic data; dividing the data into an array of relativey small three-dimensional cells; determining in each cell the semblance/similarity, the dip and dip azimuth of the seismic traces contained therein; and displaying dip, dip azimuth and the semblance/similarity of each cell in the form of a two-dimensional map. In one embodiment, semblance/similarity is a function of time, the number of seismic traces within the cell, and the apparent dip and apparent dip azimuth of the traces within the cell; the semblance/similarity of a cell is determined by making a plurality of measurements of the semblance/similarity of the traces within the cell and selecting the largest of the measurements. In addition, the apparent dip and apparent dip azimuth, corresponding to the largest measurement of semblance/similarity in the cell, are deemed to be estimates of the true dip and true dip azimuth of the traces therein. A color map, characterized by hue, saturation and lightness, is used to depict semblance/similarity, true dip azimuth and true dip of each cell; true dip azimuth is mapped onto the hue scale, true dip is mapped onto the saturation scale, and the largest measurement of semblance/similarity is mapped onto the lightness scale of the color map.
Abstract:
A propylene polymer made using a magnesium halide-supported, titanium-containing solid catalyst component having a broad processing window is produced by incorporating into the polymerization catalyst system a selected alkyl methyldimethoxysilane, preferably isobutylmethyldimethoxysilane. Useful articles made from such resin include OPP film.
Abstract:
Alpha-olefin oligomer is prepared by contacting an alpha-olefin monomer which contains from about 6 to about 20 carbon atoms with a catalyst system comprising boron trifluoride, a protic promoter, and an organic sulfone, sulfoxide, carbonate, thiocarbonate, or sulfonate. Oligomer containing as much as 50 % or more of dimer can be produced at high conversions, at modest reaction temperatures, and in acceptably short reaction periods.
Abstract:
A method for determining the reservoir properties of a solid carbonaceous subterranean formation is disclosed. The method uses field data obtained from an injection/flow-back test, which utilizes a gaseous desorbing fluid, in conjunction with reservoir modeling techniques to determine the reservoir quality and the enhanced methane recovery characteristics of the formation.
Abstract:
A process and catalyst are provided for dehydrogenating a hydrocarbon feedstock and producing an olefinic product. The process comprises contacting the feedstock at dehydrogenation conditions with a dehydrogenation catalyst comprising from about 0.01 weight percent to about 5.0 weight percent of a platinum group metal, from about 0.02 weight percent to about 10.0 weight percent of zinc, and a support component comprising borosilicate and an alkali metal.
Abstract:
The invention provides an improved method for producing synthesis gas from lower alkanes (10) which utilizes molten baths (24) as reactors. A molten metal oxide bath delivers oxygen to a feed stream containing lower alkanes and enhances oxidation of the lower alkanes to produce carbon dioxide and a molten elemental metal. In a molten metal bath, the metal is regenerated to metal oxide by contact with a regenerant such as air. Heat evolved in the molten baths is transferred to an endothermic reactor (36) where a portion of the carbon dioxide is converted to a mixture of carbon oxides and hydrogen.
Abstract:
A collapsed composition is described which is substantially composed of microcrystallites collectively of formula (I), where M is a divalent metal, M is a trivalent metal, and T is vanadium, tungsten, or molybdenum. The microcrystallites are so small as to be undetectable through conventional x-ray diffraction techniques, yet high resolution electron microscopy reveals that a substantial portion of the microcrystallites are composed of a solid solution having aluminum oxide molecularly dispersed in a divalent metal monoxide crystal structure. Another portion of the microcrystallites are constituted by a spinel phase. The collapsed composition is suitable as a sulfur oxide absorbent, having comparatively high capacity and comparatively fast absorption and desorption rates. The collapsed composition may be produced by heat treating a layered mixed hydroxide clay having interlayer anions in monometalate form. A sulfur oxide separation process is also presented. The process can be operated cyclicly and integrated with any of several well-known fluidized bed catalytic cracking processes.
Abstract:
A lubricating grease having superior penetration, dropping point, and shear stability properties is provided comprising a base oil, an additive package, a urea-containing thickener, and a lithium soap thickener.
Abstract:
A method for creating a historical record of the manufacturing, transportation and location history of steel pipe joints includes predetermined characteristics of the pipe joints. During manufacture, the heat number and coil number of the steel used to make each pipe joint is recorded. Each pipe joint is assigned a unique joint number, which is also recorded. A label containing the heat number, coil number and joint number is created and attached to the corresponding pipe joint. The pipe joints are then transported to a final destination. The exact location of the final destination is compiled into a historical record in which the location of the final destination is associated with the heat number, coil number and joint number for each pipe joint. Finally, the labels are removed from the pipe joints to prevent damage to sensitive components in the completed pipeline.
