Seismic Processing-Imaging

Geophysical Processing & Imaging From the field to the final volume, seismic data goes through many processes and workflows. Data conditioning encompasses a wide range of technologies designed to address numerous challenges in the processing sequence—from data calibration and regularization to noise and multiple attenuation and signal enhancement. Source & Receiver Corrections: elimination of seismic wavelet variations caused by irregularities in acquisition geometry and other aspects of acquisition. Noise Attenuation: a suite of tools to remove coherent and random noise in land and marine seismic data, including wind and swell noise, mud roll, ambient noise, and seismic interference.
Multiple Attenuation: demultiple algorithms to obtain the optimal solutions for a wide range of scenarios. Velocity Model Building & Updating: Algorithms and workflows that address all acquisition configurations and geologies. Prestack Migration Algorithms: ability to handle all geological complexities and seismic acquisition environments and designs, including the latest full-azimuth surveys. Multicomponent Processing: a comprehensive array of algorithms and workflows to maximize the value of your multicomponent data, whether traditional 2C/PZ data from an ocean-bottom cable or PS data from mode-converted shear waves. Time-Lapse Seismic Processing: a proven approach to 4D processing with step-by-step removal of the effects of differing acquisition systems and unrepeated coverage, using dedicated time-lapse algorithms.
