| 20120038642 | Systems and Methods for Imaging Waveform Volumes - Systems and methods for imaging waveform volumes. An image of the waveform volume may be drawn on a display device as a two-dimensional image or a three-dimensional image of a sampling probe and redrawn in real-time at interactive rates using a graphics accelerator or a graphics card. The image of the waveform volume may also include seismic-data traces that are color-filled according to texture coordinates for pixels on the display device that intersect the waveform volume. | 02-16-2012 |
| 20120037359 | Systems and Methods for Improved Positioning of Pads - Systems and methods for the automated positioning of pads and orienting of slot templates for the pads. The systems and methods also include automated adjustment of well path plans from a pad to selected well targets. | 02-16-2012 |
| 20120020186 | Seismic Imaging Systems and Methods Employing a Fast Target-Oriented Illumination Calculation - In various disclosed seismic imaging systems and methods, a fast target-oriented illumination calculation technique is employed to obtain a data volume or “matrix” of approximate illumination values. These illumination values enable an image matrix of “true reflectivity” values to be found. The illumination values are derived from Green's functions which, rather than being calculated and re-calculated on a shot-by-shot basis, are calculated in multi-shot groups and combined with a rolling-sum to greatly reduce the computational overhead. As a consequence, the disclosed systems and methods can provide target region illuminations more quickly and/or with higher quality than those systems relying on conventional 3D wave-equation illumination. | 01-26-2012 |
| 20110316883 | Systems and Methods for Computing a Variogram Model - Systems and methods for computing a variogram model, which utilize a variogram map and a rose diagram to compute the model. | 12-29-2011 |
| 20110273959 | Data Acquisition and Prestack Migration Based on Seismic Visibility Analysis - Seismic visibility analysis of selected subsurface structures is employed to determine surface locations offering high visibility of target events. These locations can then be used as a basis for acquiring additional seismic survey data and/or selecting existing traces for re-migration with more sophisticated migration methods. With either usage, the newly migrated data is expected to offer enhanced images of the target event. In some embodiments, the visibility determination includes using a wave equation based propagator to find, for each of multiple simulated shots, a reflection wavefield from the target event in a seismic model; and to calculate, for each of multiple receiver positions, a contribution signal from each reflection wavefield. The visibility determination further includes converting each contribution signal into a source-receiver visibility value. Because data acquisition and/or re-migration is limited to the selected region, the imaging effort for the target event is significantly reduced. | 11-10-2011 |
| 20110254843 | System and Method for Real-Time Co-Rendering of Multiple Attributes - Systems and methods for enhancing the combined image of multiple attributes without comprising the image of either attribute. The combined image of the multiple attributes is enhanced for analyzing a predetermined property revealed by the attributes. The combined image can be interactively manipulated to display each attribute relative to an imaginary light source or highlighted using a specular component. The systems and methods are best described as particularly useful for analytical, diagnostic and interpretive purposes. | 10-20-2011 |

| 20090231955 | FAULT FILTER FOR SEISMIC DISCONTINUITY DATA - Various methods are disclosed for identifying faults in a seismic data volume. In some method embodiments, the fault identification method comprises determining a planarity value for each of multiple positions of an analysis window in the data volume. The planarity value may be indicative of the planarity of discontinuities in the analysis window, and may be further filtered by limits on the verticality and centrality of the discontinuities. Thus a filter may be determined for suppressing relatively non-planar, relatively non-vertical, and relatively un-centered discontinuities from a discontinuity display, thereby enhancing a display of faults present in the seismic data volume. | 09-17-2009 |
