Non-structural Traps and Methods of Investigation

The study of non-structural traps is based on the detailed analysis of all geological and geophysical data. The detailed approach depends on the structure itself and on its geological evolution as weU as on its petroliferous properties. The most favourable factors are  

In the first stage of this investigation it is advisable to prepare a map of the angular unconformities and the facies changes. Usually all these data are compiled from 

Preparation of Lithostratigraphic Sections and Maps as weli as Unveiiing of Wedging and Lithoiogicai Substitutions 

The delineation of local traps was facilitated by combining the stripped-off paleo-geological map with the map of the present structure. In this way we were able to exclude certain disturbed portions of wedge zones where the traps have been destroyed by later tectonic movements.
