This sequence of operations increases reliability of results when measuring relative permeability using the model and displaying relative permeability measurements to user.

To conserve computational resources, the simulations are preferably performed on a representative elementary volume (REV). The determination of a multiphase REV can be determined, in some method embodiments, by deriving a porosity-related parameter from a pore-matrix model of the material; determining a multiphase distribution within the material's pores; partitioning the pore-matrix model into multiple phase-matrix models; and deriving the porosity-related parameter from each phase-matrix model. The parameter's dependence on phase and saturation can then be determined and analyzed to select an appropriate REV size.

    Abstract: A testing system for analyzing a 3D digital volume of a material sample. The testing system defines several test volume sizes with each test volume size including a different numbers of voxels, defining the size of portions of the 3D digital volume to analyze. For each test volume size, the testing system acquires two adjacent portions of 3D digital volume at the test volume size currently being analyzed. The testing system calculates a material property value for the two adjacent portions of the 3D digital volume, and a difference value between the two adjacent portions of the 3D digital volume. The process is repeated over the different test volume sizes. The testing system calculates mean difference values for the different test volume sizes, from which it determines a representative elementary volume.

  • Patent number: 9052407
    Abstract: Method for building a seismic imaging velocity model, particularly at the boundary of a geo-body, and to perform imaging, by taking into account the elastic reflection and scattering information in the seismic data. More illumination of the base and flanks (or in general, the boundary) of the geo-body is provided from (a) inside of the geo-body (502), with elastically converted waves at the geo-body boundary used (via elastic RTM flooding); and (b) from outside the geo-body (503), by utilizing prism waves with elastic RTM to handle the phase correctly in the model building step. The increased illumination and correct elastic phase are used for geo-body boundary determination. Elastic RTM is then applied (505), along with the elastically derived imaging velocity model, to maximize the use of elastic energy in the imaging step, and to obtain the correct image with the correct phase.

A processor applies a classifier to the sensor values to identify a label for each sub-area in each aerial image and to thereby generate an initial label sequence for each sub-area. The processor identifies a most likely land cover state for each sub-area based on the initial label sequence, a confusion matrix and a transition matrix. For each sub-area, the processor stores the most likely land cover state sequence for the sub-area.

  • Patent number: 8958604
    Abstract: Data transmission from a bottom hole assembly (BHA) includes obtaining a scan from multiple scans forming a downhole data log of a borehole within a subterranean formation. The scan includes a sequence of data items from a sensor in the BHA located in the borehole. Each data item corresponds to an azimuth angle of the sensor. Further, compressed scan data is generated from the sequence of data items on a per-scan basis, and transmitted, using a pre-determined borehole telemetry, to a surface unit.

  • Publication number: 20150043787
    Abstract: A testing system for performing image based direct numerical simulation to characterize petrophysical properties of a rock sample under the simulated deformation condition, for example as representative of subsurface conditions. A digital image volume corresponding to x-ray tomographic images of a rock sample is segmented into its significant elastic phases, such as pore space, clay fraction, grain contacts and mineral type, and overlaid with an unstructured finite element mesh. A simulated deformation is applied to the segmented image volume, and the resulting deformed unstructured mesh is numerically analyzed, for example by way of direct numerical simulation, to determine the desired petrophysical properties.

  • Publication number: 20150030209
    Abstract: A method of analysing seismic data from a geological volume is provided. The geological volume is divided into a plurality of voxels. For each voxel a respective neighbourhood is defined which includes that voxel and a predetermined arrangement of neighbouring voxels. For each voxel, the respective normal vectors of a seismic attribute vector field derived from the seismic data are calculated. For each voxel, a respective local structure tensor based on the normal vectors of the voxels of the respective neighbourhood is calculated. For each voxel, the value of an expression which includes one or more of the eigenvalues (?1, ?2, ?3) of the respective local structure tensor is calculated. The method can be used for seismic surveying, or to manage operation of or drilling of a subterranean well.

  • Publication number: 20150023564
    Abstract: A system and method for estimating porosity distribution in a region of interest of a geologic formation from a resistivity image log representative of the geologic formation is disclosed. A normalization factor representative of a rock matrix based on a first resistivity value and an image point factor based on a second resistivity value are calculated and compared to identify points in the resistivity image log that correspond to the secondary porosity. The normalization factor and image point factor are recalculated based on a different first resistivity value and a different second resistivity value as necessary to identify additional points in the resistivity image log that correspond to the secondary porosity until a termination criterion is met. The method may further include a porosity calibration operation and one or more artifact corrections.

  • Patent number: 8928778
    Abstract: A camera device includes an imaging unit generating an imaging area image in which an imaging area is captured from above, and a display-image generation unit generating a display image of an imaging object moving in the imaging area by use of an clipped image clipped from the imaging area image. In this case, an clipping reference position P corresponding to the imaging object in the imaging area image is determined, and a reference distance r between an imaging reference position O corresponding to the imaging unit and the clipping reference position P in the imaging area image is calculated. When the reference distance r is short, a rotation angle ?NEW for rotating the clipped image in generating the display image is calculated based on a reference angle ? corresponding to an inclination of the imaging object in the imaging area image and the reference distance r.

  • Patent number: 8908926
    Abstract: A method of 3D object delineation from 3D seismic data comprising the steps of, providing 3D seismic data; processing the data based on at least one characteristic whereby said characteristic is extracted from the data and compared with at least one reference characteristic and delineated based on the comparison, and defining a geological element based on the delineation. The characteristics may be adjusted. Data can be processed based on one characteristic then processed based on a second characteristic or data is processed based on two characteristics substantially simultaneously. Data may be processed n times producing n delineations from which the geological element is defined. An algorithm is provided for processing the data which may shift an evolving shape description of an object between explicit and implicit representations, where each shift applies a transformation to the object. Multiple sources of data may be utilized simultaneously to drive the delineation process.
