Summary:
The main idea of the seismic data processing is to obtain a true geological model and final reserves estimate. Apart from the geological and geophysical parameters, structural characteristics, such as the size and position of structures in space, undoubtedly influence the amount of reserves. In areas with complex geological structure, the time and depth scale do not correspond to each other. Uncertainties in geological characteristics can lead to large errors in the estimation of reserves. Thus, reliable depth imaging of the environment(media) is one of the main tasks, while the uncertainty of structural constructions can be quite large, depending on the complexity of the geological structure. The work demonstrates the interpretational approach to the process of the velocity model building and the method of qualitative accuracy estimation of velocity model in case of complex geological conditions.
