Abstract
3D seismic data interpretation of Neocomian deposits shows some amplitude zones related to sediment transport directions of likely channel origin. More precise identification needs to be assessed during 3D seismic data and experience accumulation for exploration and field development. The data obtained show high necessity of new approach in interpretation of seismic anomalies related to real geological bodies.
Channel-like anomalies distinguished in clinoform unit and in overlapping littoral terrigenous deposits can indicate net thickness increasing and local improvement of reservoir properties in the target interval. At the same time, linear anomalies are often complicating factors in field development. The aim of this work is to show the main peculiarities of interpretation and modeling of some specific but widespread channel-like anomalies (shoe-string, linear features) in terrigenous deposits of Western Siberia observed on 3D seismic profiles and well data.
