|20130021873||METHOD AND DEVICE FOR WAVE FIELDS SEPARATION IN SEISMIC DATA - Apparatus, computer instructions and method for processing seismic data related to a subsurface of a body of water. The method includes receiving input data for a vertical direction and radial direction and/or from a hydrophone, applying a radon transform to the input data, separating primary signals from ghosts signals based on the vertical and radial components, applying an inverse radon transform to determine up-going and down-going wave fields in a time-distance domain, and separating interfering up-going and down-going wave fields that are recorded by the same receivers.||01-24-2013|
|20120320711||METHOD AND DEVICE FOR MARINE SEISMIC ACQUISITION - Method and system for improving azimuth distribution. The system includes plural streamers towed by a streamer vessel; a central source towed by the streamer vessel; first and second front sources located in front of the plural streamers along a traveling direction of the streamer vessel; and first and second tail sources located behind of the plural streamers along the traveling direction. The offset distance between the first and second tail sources, along a cross-line direction, is larger than an offset distance between the first and second front sources.||12-20-2012|
|20120224453||METHOD AND DEVICE FOR ALTERNATING DEPTHS MARINE SEISMIC ACQUISITION - System and method for enriching a bandwidth of seismic data related to a subsurface of a body of water. The system includes streamers and sources that are towed at alternating depths during consecutive and/or adjacent line of sails or during the same line of sail.||09-06-2012|
|20120075954||Device and Method for Calculating 3D Angle Gathers from Reverse Time Migration - A method for calculating angle domain common image gathers (ADCIGs). The method includes calculating a source wavefield p||03-29-2012|
|20100149910||SEISMIC ARRAY TOWING SYSTEM - A system for a more efficient towing of a marine seismic array comprising one or more diverters attached to each lead-in cable. Because each lead-in cable has its own diverter, the need for dedicated towing ropes and taglines between lead-in cables is eliminated, thereby reducing the overall drag and fuel consumption. The diverters of the present invention are directly attached to the respective lead-in cables and are submerged, eliminating the need for taglines and additional flotation. The diverter of the present invention comprises of either a single span-wise hydro foil or two foil sections and is steerable. Similarly, the diverters of the present invention can be installed on the umbilical cables of seismic source subarrays to obtain the same benefits. As such, at least one diverter of the present invention can be attached directly to at least one umbilical cable of the seismic source subarray.||06-17-2010|
