Seismic Data Processing As An Aid For Quality Improvement Of Signal.

      Аннотация: Each type of geophysics technique consists of three different processes. It begins with collecting the available data of the study area, by making a new survey in the given area, measuring with different tools, and recording the output results data. Finally, the old data is collected in the study area such as geological data, maps, and geophysics data in order to correlate it with the new data to obtain the optimum results. This is the first process, which called seismic data acquisition. The second process is called seismic data processing in which we get rid of the unwanted data (noise data) by applying different flows, so that we can get enhancement of the signal to noise ratio. After removing the noise we start to judge the output results by the interpretation of the final seismic section, this process is called seismic data interpretation. These three processes are very important to complete full study and to detect the target from this study. It's worth noting that without accurate result in seismic data processing step (second step); we cannot obtain an accurate final seismic section to make a good interpretation; subsequently, missing the objective from the survey.
