  • Publication number: 20030201772
    Abstract: An method and system are disclosed for NMR echo-train data acquisition and processing for enhanced vertical resolution for a given signal to noise ratio. In one aspect, the method is based on providing an estimate of non-formation signal components and removing the estimate from the NMR signals. Computation of the estimate is done from the data itself or using a direct measurement of non-formation signals. In another aspect, the functions of reducing coherent noise components is separated from the function of reducing the random noise components, to enhance the resolution of the NMR pulse echo data for a given signal to noise ratio (SNR) of the data. Combination processing is disclosed, which enables efficient filtering of the input NMR data for both relatively high and relatively low SNR of the formation data.

  • Publication number: 20020147757
    Abstract: An apparatus and method are provided to support the provision of context-sensitive help functions in a back-end HTML/XML server. The apparatus provides partner-sensitive help functions to users that have been redirected from a plurality of partner sites to the back-end server. The apparatus has a data base and a context-sensitive help engine. The data base stores general help data, as well as partner-specific metadata corresponding to the plurality of partner sites. The context-sensitive help engine is coupled to the data base. The context-sensitive help engine receives a help transaction request that has been redirected from a specific one of the plurality of partner sites. The context-sensitive help engine provides specific help functions in response to the help transaction request, where the specific help functions correspond to the specific partner site.

  • Patent number: 6337568
    Abstract: An interpretation method and system for NMR echo-train data in thinly laminated sequences. The invention uses geological information obtained at higher vertical resolution, such as using Electric Micro Imaging, to enhance the vertical resolution of echo-train data, and thus avoids log interpretations in which the hydrocarbon potential of the formation can be misread because low resolution logs tend to provide an average description of the formation. Such averaging is especially problematic in thinly laminated sequences that consist of highly permeable and porous sand layers and less permeable silt or essentially impermeable shale layers. In a preferred embodiment, using the additional high-resolution formation information one can estimate the typical T2-spectra of lithological laminae, and significantly enhance the permeability estimate in the laminated sequences.

  • Patent number: 6298178
    Abstract: An integrated optical circuit formed on an optically conductive substrate having light absorbing means comprising one or more doped areas (1) of the substrate where the doping concentration is greater than that of areas of the substrate forming the optical circuit (2) to absorb stray light in the substrate which is not guided by components of the optical circuit.

In a preferred embodiment, using the additional high-resolution formation information one can estimate the typical T2-spectra of lithological laminae, and significantly enhance the permeability estimate in the laminated sequences. The method and system are applicable to any temporal data from other logging tools, such as the thermal neutron decay log and others.

  • Patent number: 3992559
    Abstract: The invention relates to the labelling of textile and other flexible sheet articles in which a marking element is used which is adapted to be attached and bonded to the article by heat and pressure, said element including a heat-curing film-forming resin system in the presence of blocked cross-linking groups and under acid conditions, such resin system becoming heat-cured during the attachment of the marking element to the article to form an inert, insoluble and wear-resistant marking on the surface of the article. The resin system may be an alcohol-soluble copolyamide in the presence of a cross-linking agent which may be a precondensed alcohol-modified formaldehyde or aminoplast resin containing alkoxy alkyl group; or it may be a dispersion of a film-forming addition resin system at least one monomer of which contains groups capable of reacting with similar cross-linking agents or comonomers bearing alkoxy-alkyl groups.
