    Abstract: A system to provide on-demand fetching of sequential sets of seismic data to local memory from slower storage mediums prior to performing computing operations, such as horizon auto-tracking, amplitude extraction and seismic attribute generation. As a result, the performance of the storage infrastructure (e.g., hard drives, storage filer "file server" over network, etc.) is maximized and the local memory/cache speed is fully utilized to deliver optimal system performance even when working with large seismic datasets that exceed the storage capacity of the local memory.

    Abstract: An interpolated subsurface volume including control cells and derived cells is obtained, whereby the derived cells include attribute values derived from the control cells. A set of peak cells is selected according to attribute values. The attribute value from the derived cells or the control cells in the peak cell is a local extrema. A correlation coefficient is determined that characterizes a spatial relationship between the location of the peak cells and the location of the control cell. The correlation coefficient is presented.

    Abstract: A method for raycasting based on an irregular grid. The method includes raycasting, in a static mode, rays based on the irregular grid to generate a static image of a three dimensional (3D) volume dataset. The 3D volume dataset includes irregular grid cells based on the irregular grid. The method further includes reducing a tally of the rays to generate a reduced tally of rays based on a rendering time of the static image and an animation frame rate, and generating, in a dynamic mode, an animation of the 3D volume dataset at the animation frame rate by at least performing raycasting based on the reduced tally of rays.

    Abstract: A method for seismic geological lineation mapping, wherein a seismic dataset is collected, with information about minor lineations generated by subtle structural geological features in an underground earth formation. Seismic attribute volumes are identified in the seismic dataset, relating to trace continuity, amplitude, frequency and phase. The attribute volumes may have an insufficient resolution to display the minor lineations. A seismic multivolume lithological lineation map is generated, in which single attribute lineation maps generated for each of the identified seismic attribute volumes are combined to accurately display the minor lineations generated by the subtle geological features.

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 (λ 1 , λ 2 , λ 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.

    Abstract: Embodiments of a method for enhancing flat spots in 3D seismic interpretation are disclosed herein. Embodiments of the method generally involve an operation of horizontally stacking (summing) traces within a user defined elongate area. The user may define the size and shape of the elongate area. In addition, the elongate area may be automatically aligned to a user defined axis such as without limitation, the structure strike. By aligning an elongate area operator with a selected or user selected axis, and with appropriate choice of axis length, it is possible to constrain the stacking operation within geologic strata, allowing the user to image even narrow flat events that wrap around a subterranean structure. Further details and advantages of various embodiments of the method are described in more detail herein.
