  • Publication number: 20140044315
    Abstract: A method for increasing the accuracy of a target property value derived from a rock sample is described in which the sample is scanned to obtain a three-dimensional tomographic digital image which can be processed to pore space and solid material phases through a segmentation process. A process is used which revises the segmented volume, e.g., by increasing pore space connectivity, in a manner affecting the target property value that would be derived. Another described method increases the accuracy with which a segmented volume represents a material sample having structure not adequately resolved in an original three-dimensional tomographic digital image. Further, a system for performing the processes, and a segmented digital volume which more accurately represents a sample of a porous media, are described.

  • Publication number: 20130308831
    Abstract: A method is provided for efficiently characterizing rock traversed while drilling a borehole for hydrocarbon reservoir development. A rock sample can be obtained having a provenance of collection linked to a specific region of the borehole, which is scanned to obtain a 2D digital image that is segmented to pixels characterized as pore space and as mineral matrix and defining a boundary between them. A transform relationship, for example, a form of the Kozeny-Carman equation adapted for application to a 2D segmented image environment, can be applied to calculate the estimated value for a target rock property, which can be absolute permeability, relative permeability, formation factor, elasticity, bulk modulus, shear modulus, compressional velocity, shear velocity, electrical resistivity, or capillary pressure, and the estimated value is used to characterize the rock at that region of the borehole.

    Abstract: A method of constructing an image representing the distribution of a categorical physical property representative of an underground zone having applications for petroleum reservoir development. A first training image representative of a geometrical structure of the categorical property is constructed. Training images representative of the distributions of several auxiliary properties are then constructed from the first training image. A probability law of the categorical property and a probability law of each auxiliary property are determined, from each training image, for a given pixel according to the values of the neighboring pixels. A probability law of the categorical property is calculated from these laws and from the images representative of the distribution of the auxiliary physical properties in the zone, and for each pixel of the image to be constructed. Finally, the value of the categorical property is determined by carrying out a random selection for the calculated probability law.

    Abstract: Method for efficient computation of wave equation migration angle gathers by using multiple imaging conditions. Common reflection angle or common azimuth gathers or gathers including both common reflection angles and common azimuth angles are produced as the data are migrated. In the course of either wave equation migration or reverse time migration, the pressures and particle motion velocities that need to be computed are sufficient to also compute the Poynting vector pointing in the direction of source-side (35) or receiver-side (37) wavefield propagation. From that, the reflection and azimuth angles can be computed (38).

Information relating to the marked up digital image is electronically transmitted and/or electronically stored so as to facilitate the detection of the presence or the absence of the at least one underground facility within the dig area.

  • Patent number: 8351654
    Abstract: Image processing using geodesic forests is described. In an example, a geodesic forest engine determines geodesic shortest-path distances between each image element and a seed region specified in the image in order to form a geodesic forest data structure. The geodesic distances take into account gradients in the image of a given image modality such as intensity, color, or other modality. In some embodiments, a 1D processing engine carries out 1D processing along the branches of trees in the geodesic forest data structure to form a processed image. For example, effects such as ink painting, edge-aware texture flattening, contrast-aware image editing, forming animations using geodesic forests and other effects are achieved using the geodesic forest data structure. In some embodiments the geodesic forest engine uses a four-part raster scan process to achieve real-time processing speeds and parallelization is possible in many of the embodiments.

  • Patent number: 8345929
    Abstract: Method for visualizing and comparing two images or volumes of data of physical quantities or information referable to the same, recorded by means of suitable equipment, comprising the following steps: —defining which of the two quantities will be represented as color variations, and which as brightness variations; —defining a chromatic representation system based on three color coordinates, in which one coordinate represents the brightness and the other two coordinates represent appropriate color attributes; —applying a suitable transformation to the values of the physical quantities to be represented, so that the values of the physical quantities to be visualized are transformed from the original coordinates into the preselected chromatic coordinates; —transforming the values of the quantities to be visualized from the system of pre-selected coordinates into the chromatic coordinates typical of the pre-selected visualization system; —visualizing the image/volume containing the combination of the two quantiti

  • Patent number: 8331624
    Abstract: The invention relates to a method for surveying at least one target using a geodetic device. According to said method, a camera of the device captures a visual image and surveys an angle and/or a distance to the target with geodetic precision, the angle and/or distance surveillance being supported or controlled by the visual image. At the same time of capture of the visual image at least two distance points of a distance image are captured as the spatial distribution of discrete distance points in the area of detection. When the visual image and the distance image are correlated with each other, the target is recognized or the measuring process is controlled.

  • Patent number: 8331627
    Abstract: A method and system for generating an entirely well-focused image of a three-dimensional scene. The method comprises the steps of a) learning a prediction model including at least a focal depth probability density function (PDF), h(k), for all depth values k, from historical tiles of the scene; b) predicting the possible focal surfaces in subsequent tiles of the scene by applying the prediction model; c) for each value of k, examining h(k) such that if h(k) is below a first threshold, no image is acquired at the depth k? for said one tile; and if h(k) is above or equal to a first threshold, one or more images are acquired in a depth range around said value of k for said one tile; and d) processing the acquired images to generate a pixel focus map for said one tile.

  • Patent number: 8331696
    Abstract: To provide an update region detection device capable of accurately detecting an update region from plot data on a computer screen. In an update region detection unit (125), a pixel comparison unit (601) compares a difference between values of pixels at the same position in each of a reference frame and a current frame, with a first threshold and a second threshold, the second threshold being a value greater than the first threshold. An update region extraction unit (602) extracts, an update region, a group including a pixel where a difference greater than the second threshold has been detected, from among a group of pixels where a difference greater than the first threshold has been detected.

  • Publication number: 20120277996
    Abstract: The subject disclosure relates to methods for determining representative element areas and volumes in porous media. Representative element area (REA) is the smallest area that can be modeled to yield consistent results, within acceptable limits of variance of the modeled property. Porosity and permeability are examples of such properties. In 3D, the appropriate term is representative element volume (REV). REV is the smallest volume of a porous media that is representative of the measured parameter.
