  • Patent number: 7072767
    Abstract: The present invention provides for a method and apparatus for seismic data processing. Prestack seismic data is obtained that contains a plurality of reflectors. Non-parallel moveout of the plurality of reflectors is utilized to determine a source wavelet using an L2-Norm and a reflectivity parameter using an L1-Norm. The source wavelet and reflectivity parameters can be determined simultaneously. Source and reflectivity determination may further comprise minimization of a model objective function. The model objective function may be a function of at least one of i) said source wavelet, ii) a gradient parameter and iii) an intercept parameter. An AVO intercept and gradient parameters can be determined using the determined source wavelet and reflectivity parameter. Constraints may be placed on parameters to ensure physically realistic solutions.

  • Patent number: 7072768
    Abstract: A method for laterally extrapolating shallow soil properties using soil samples and seismic amplitude data within a seismic coverage area entails obtaining seismic amplitude data for the seismic coverage area and obtaining average soil property and soil impedance data for locations in the seismic coverage area. The seismic amplitude data is compared with the soil impedance data at locations in the seismic coverage area forming an amplitude impendence formula. The seismic amplitude data is converted to soil-calibrated impedance data using the amplitude impendence formula. The method continues by comparing an average of desired soil property and the soil impedance data at locations in the seismic coverage area forming a soil property-impendence formula. A target soil property is selected and the soil calibrated impedance data is converted to the target soil property using the soil property impendence formula. The method ends by extrapolating the target soil property over the entire seismic coverage area.

  • Patent number: 7069124
    Abstract: Robotic systems for modeling, mapping and exploring subterranean void spaces such as mines, caves, tunnels, bunkers, and conduits. Robotic modeling of subterranean voids is generally enabled by a procedural system consisting of preprocessing, ingress, void modeling, mapping and navigation, exploration, conveying payloads other than void modeling sensors, egress, and post processing. The robots can either be imposed mobility or can be self mobile with either autonomous, remote, teleoperated, or manual modes of operation. The robot may optionally transform from a compact size into a more conventional operating size if the operating size exceeds the void entry opening size. Void geometries with flat floors are amenable to robot locomotion such as rolling, crawling, walking or swimming. Alternatively, irregular floor geometries that preclude self mobilization may be accessible by imposed mobilization such as dropping or pushing a movable robotic sensor into such voids.

  • Patent number: 7058511
    Abstract: Methods, computer-readable media, and systems are provided for determining whether a data point indicates a presence of a sub-visible cloud using visible near-infrared data and short wavelength infrared data. A data point is selected from an imaging study of an area potentially covered by at least one of visible clouds and sub-visible clouds. A presence of a sub-visible cloud is determined. The determination is made by comparing a cirrus-band reflectance of the data point with a sub-visible cirrus-band reflectance threshold. The data point is classified as a sub-visible cloud point if the cirrus-band reflectance of the data point exceeds the sub-visible cirrus band reflectance threshold.

  • Patent number: 7043370
    Abstract: A method is discussed for obtaining resistivity values in a horizontal or highly-deviated wellbore penetrating an anisotropic formation layer. Multi-component data is obtained from the formation layer. An initial value of horizontal and vertical resistivity can be determined by using a whole space model and assuming an isotropic layer. Revised values of the vertical and horizontal resistivities are obtained through a first and second inversion process. A first inversion is performed on the horizontal resistivity, holding a value of vertical resistivity constant. A second inversion is performed on the vertical resistivity, holding a value of horizontal resistivity constant. These inversions are iterated until a desired convergence is achieved.

  • Patent number: 7043367
    Abstract: A method for forming a 2D or 3D diffusive type model allowing simulation of multilithologic filling of a sedimentary basin over geologic periods. The model is based on the numerical simulation of the evolution of a sedimentary basin, from the past to the present, in a series of time intervals. In each time interval, three major phenomena interact and are numerically modelled: basin deformation, sediment supply and transportation of these sediments in the deformed basin. To model sediment transportation, long-term permanent transportation (creeping, slow diffusion process, etc.), short-term transportation (due to rain and flood) and catastrophic transportation (notably due to cliff collapse) are taken into account using an exponential water velocity model.

  • Patent number: 7043366
    Abstract: An improved method is disclosed for collecting or assembling scalar potential data measurements that are to be subsequently prepared as a surface representation for analysis via frequency domain transform filters. Measurements are made over a geographic reference region which extends in all cardinal directions from the center of some previously determined primary region. The reference dimensions must contain the primary region and must be plural multiples of the greatest depth to be considered in analyzing the contributions to the measurements. A combined or separate improved method for delineating or defining geospatial information contributing to a scalar potential surface is disclosed. This method is implemented using traditional statistical techniques to construct an histogram from the set of values comprising a surface representation. This histogram constitutes a Spatially Correlated Potential Spectrum for the surface.

  • Patent number: 7039526
    Abstract: A set of pre-stack seismic data is downward extrapolated, by first determining a migration interval in the seismic data set. A maximum error criterion is selected for the migration interval. A maximum relative error in phase calculated as a function of frequency, propagation angle, and the relative variation in velocity in the migration interval. The maximum relative error in phase is compared to the maximum error criterion. The type of extrapolation to use in the migration interval is determined from the comparison of the maximum relative error in phase to the maximum error criterion. The type of extrapolation is selected from a set comprising Gazdag phase-shift extrapolation, split-shift Fourier extrapolation, and implicit finite difference extrapolation.

  • Patent number: 7027922
    Abstract: A method is discussed of obtaining a parameter of interest of an earth formation, typically a formation resistivity or a distance to a bed boundary, in conditions where an induction tool is using having a body with finite, non-zero conductivity. The method substantially removes the effects of the conductivity of the tool from the signal received from the earth formation. A Taylor series expansion in one half of odd integer powers of time is used to represent the received signal. At least one leading term of the Taylor series expansion can be subtracted from the second signal. A filtering operation is applied to the second signal to remove the terms most dominated by pipe effects. Typical filtering operations can be a differential filtering operation or an integral filtering operation.

  • Patent number: 7006918
    Abstract: A method for the measurement of the stresses and pressure perturbations surrounding a well, and a system for computing the optimum location for initiating a hydraulic stress fracture. The technique includes using sensors attached to the wellbore casing connected to a data analyzer. The analyzer is capable of analyzing the stresses on the well system. Using an inverse problem framework for an open-hole situation, the far field stresses and well departure angle are determined once the pressure perturbations and stresses are measured on the wellbore casing. The number of wellbore measurements needed for the inverse problem solution also is determined. The technique is also capable of determining the optimal location for inducing a hydraulic fracture, the effect of noisy measurements on the accuracy of the results, and assessing the quality of a bond between a casing and a sealant.

  • Patent number: 7003402
    Abstract: A method of processing data sequences obtained at substantially the same time at locations spatially separated from one another is disclosed. A sequence indicative of a measure of spread of the data sequences or of selected data sequences is determined. A common signal data sequence may also be determined from the (selected) data sequences. The measure of spread of the data sequences is preferably normalized, for example relative to the absolute value of the common signal data sequence. The measure of spread is a measure of the noise to signal ratio in the initially-obtained data sequences. It may be used to control the parameters of other processing steps performed on the data sequences. Alternatively or additionally, the measure of spread may be output, for example for monitoring by an observer. The method can be applied to the processing of seismic data obtained using a single sensor seismic data acquisition system.
