Seismic Processing of High-Resolution Offshore Mutichannel Seismic Data In this Project I worked and Processed High-Resolution Offshore Mutichannel Seismic Data in the RadExPro seismic Software. Application-specific seismic data conditioning and processing for confident imaging. Structural segmentation and Facies architecture define the reservoir heterogeneity and control the  drainage capability. The SGD Volume , recovers the internal geometry variations of the original seismic reflectors. These patterns (foot prints) tend to follow the acquisition geometry used for … The receiver cables are spaced apart from left to right at 100, 200, 100, 200, and 100 m distances. sand or gravel) layers, seismic refraction may yield incorrect results. Editing. 3) Sorting the data by absolute offset . Geomage will present it’s most innovative seismic processing software g-Platform and latest case studies of Geomage technologies. Each of the processes described above is presented in detail in subsequent chapters. Geomage will present it’s most innovative seismic processing software g-Platform and latest case studies of Geomage technologies. As shown in the next section, seemingly small errors can lead to severe imaging problems. 3) Sorting the data by absolute offset . 2) Defining the geometry . Barbados The overall objective is to introduce E&P professionals to the key concepts and principles that form the basis for value added seismic applications in exploration, field appraisal, and reservoir management. Overview The essential seismic reflection data processing flow is as follows. (Courtesy Santos Oil Ltd.), Figure 7.1-18  Fold of coverage associated with the two shooting patterns as in Figure 7.1-17. 1. Ph. Seismic data consists of a series of recorded wiggle traces that describe a set of echoes from interfaces between rock layers in the subsurface that have different rock properties. The two fault horizon slices are overlaid for comparison (right), notice that fault trends from seismic original volume are honored by the process. Its proprietary workflows, which can delineate both the geometry and the vertical extension of the reservoirs, will yield new seismic volumes to support, optimize and validate well planning and positioning. The result is a new P-impedance volume (bottom right) that captures the vertical and lateral variations of the reservoir window, as it is observed from the match between Zp logs and acoustic impedance volume. Interpolation has become an important part of our 3D processing flow for a number of reasons: It corrects for the effects of an irregular acquisition geometry by regularizing the geometry and filling in small gaps within the geometry.
