Hydrocarbon resources in the pre-salt is very rich,and eighty-five percent of oil and gas proven reserves is distributed in the presalt in PreCaspian Basin.

Accordingly,the filled stratigraphy including the pre-salt sequence,the intra-salt sequence and the post-salt seq.

Therefore,the Eslower4 layers underlying salt are important prospects for exploration in the Dongying Sag.

Features and Exploration Trends of Hydrocarbon Accumulation Assemblage of the subsalt strata in Marginal Caspian Basin of Kazakhstan;

Interpretation method of subsalt structures in significant thickness of salt beds, east merging of littoral Caspian Sea basin.;

Identifying subsalt structure and reservoir prediction in central block of eastern margin of Pre-Caspian basin.;

In seismic exploration, subsurface salt dome, as a high-velocity geologic body, brought about a series of problems to ordinary processing in time domain and interpretation, for example, false image of subsalt structure and abnormal stack velocity field.
