To meet the exploration objectives of the client. The last part of the flow charts goes through the “equivalent lateral force procedure” step-by-step. Commonly, seismic data processing procedures, such as stacking and prestack migration, require the ability to detect bad traces/shots and restore or replace them by interpolation, particularly when the seismic observations are noisy or there are malfunctioned components in the recording system. 1. The processing sequence designed to achieve the interpretable image will likely consist of several individual steps. It is a non-trivial matter to design a proper sequence of seismic data processing, called a processing flow. Figure 1.5-1 represents the seismic data volume in processing coordinates — midpoint, offset, and time. Mention the word “geometry” and people think about shapes and angles, and maybe the time they outsmarted an opponent on the pool table. Figure 1.8 shows an example of a processing flow for reflection seismic data more than 30 years ago (W. A. Schneider, unpublished class notes, 1977). Seismic data are usually contaminated with two common types of noise, namely random and coherence. A seismic interpretation study should access the following data sets:. For this purpose, we used for Chirp (2-8 kHz) seismic data. DP START Houston 2007. Incredible Data Processing Flow Chart Rice is one of the most important food crop across the world that is processed in the rice milling plants with respect to the international standards keeping in mind the uniformity and the basic quality of the grain.
