| 20090175126 | FREQUENCY SHIFT RESERVOIR LOCALIZATION - A method and system of detecting and mapping a subsurface hydrocarbon reservoir includes acquiring seismic data having a plurality of components, applying a data transform to the seismic data to obtain seismic data spectral component maxima and maxima profiles, and recording the maxima or maxima profile in a form for display. | 07-09-2009 |
| 20090310443 | Vector Migration of Virtual Source VSP Data - A walkaway VSP survey is carried out with receivers located in a borehole under a salt overhang. Redatuming of the multicomponent data to virtual sources in the borehole followed by vector Kirchhoff migration using a simple velocity model provides an accurate image of the salt face. | 12-17-2009 |
| 20100085837 | HARMONIC ATTENUATION USING MULTIPLE SWEEP RATES - A technique includes generating seismic sweep sequences. Each of the seismic sweep sequences has an associated sweep rate. The technique includes varying the sweep rates to reduce harmonic distortion present in a composite seismic measurement produced in response to the sweep sequences. | 04-08-2010 |
| 20100302906 | METHOD FOR WAVEFIELD-BASED DATA PROCESSING INCLUDING UTILIZING MULTIPLES TO DETERMINE SUBSURFACE CHARACTERISTICS OF A SUBURFACE REGION - Despite full waveform propagation capabilities offered by reverse time migration or inversion, prior art methods can generate spurious events from multiples and therefore are limited to using data without free-surface multiples. By eliminating or largely reducing artificial transmission of multiples, the enhanced reverse time migration or inversion in the present invention can correctly use data that contain free-surface and internal multiples and improve image quality or properties estimation. | 12-02-2010 |
| 20130215717 | Integrated Passive and Active Seismic Surveying Using Multiple Arrays - Microseismic mapping using buried arrays with the integration of passive and active seismic surveys provides enhanced microseismic mapping results. The system is initially set up by recording seismic data with the buried array installation while shooting a significant portion of the 3D surface seismic survey. The 3D surface seismic survey provides the following data: shallow 3D VSP data from the buried arrays; P-wave and converted wave data for the area covered by the buried array that benefits from the planned data integration processing effort; and microseismic data and associated analysis. | 08-22-2013 |

| 20110205846 | SYSTEM AND METHOD FOR ATTENUATING ALIASING IN SEISMIC DATA CAUSED BY ACQUISITION GEOMETRY - Seismic data representing the propagation of seismic energy through a geologic volume of interest is processed. The seismic energy propagates through the geologic volume of interest from one or more source locations at or near the geologic volume of interest to one or more detector locations at or near the geologic volume of interest. In processing the seismic data, the seismic energy is modeled as beams (e.g., Gaussian beams). The processing includes determining a filter for the seismic data that attenuates aliasing which may be present in the seismic data due to spacing between detector locations. | 08-25-2011 |
| 20130121110 | DEVICE AND METHOD FOR DE-BLENDING SIMULTANEOUS SHOOTING DATA WITH APEX SHIFTED RADON TRANSFORM - A device, medium and method for de-blending seismic data associated with a subsurface of the earth. The method includes receiving blended seismic data, wherein the blended seismic data includes traces having energies from two or more different shots that partially overlap; applying an apex-shifted radon transform (ASRT) to the blended seismic data to transform it from a first domain to a second domain; applying a mute processing for removing all shots except a first shot in the second domain; applying a reverse ASRT to the given shot to obtain the first shot in the first domain; and generating an image of the subsurface based on the first shot in the first domain. The procedure may be iteratively repeated to separate all shots. | 05-16-2013 |
