How to Avoid Pitfalls in Interpretation of 3D Seismic Data With Effects of Igneous Intrusion

Summary Igneous intrusions have very difficult structure on Nepa-Botuoba anteclise. Earlier, when there were only archive 2D seismic data with well information it was possible only understand their locating. Because of the poor data quality it was not possible to study it correctly. However, after we received data of 3D seismic it became possible to study properly igneous intrusions and effects which they made on the layers under it. To understand morphology of the igneous intrusion and its effects on seismic data we made modeling, seismic attribute analysis and structural interpretation. In the result, understanding of igneous intrusion influence on the 3D seismic allowed to avoid pitfalls, and make correct structural and dynamic interpretation.
