Case Study of Detailed Interpretation of Seismic Data that Significantly Complicated by Unwanted Signals Using Limited Offset Ranges

In the unexplored and poorly studied by drilling areas in the analysis of seismic important role is given to the detection of anomalies that having certain morphological features of geological events. The interpretation of these events allows us to refine the seismostratigraphic model and conduct the lithology forecast. In this connection, a factor that increases reliability of interpretation, is the detail of seismic images. In this paper we consider the way to solve problems expressed in the loss of information content of seismic data under the significant influence of unwanted signals, especially seabed multiples. Also given an example of seismic interpretation detail increasing, by the using of angle stacks.
