Geomorphological methods as applied to search for oil and gas deposits of non-anticlinal type

Abstract

Paleo-geomorphological analysis application to hydrocarbons deposits search is shown with special reference to the zone of contact between the Great Caucasus and West-Cuban foredeep. Lithological (drilling) data appeared to be highly compatible with independent paleo-geomorphological reconstructions which permitted to trace Miocene rivers valleys. Several stages of drainage network evolution in miocene are distinguished, i. e. Karaganian, Middle Sarmatian and Meotian stages, the latter being synchronous with the 4th productive horizon formation. Most debeloped river network existed in Middle Sarmatian and Meotian epochs. The technique is shown to be advisable for areas similar in structure to the region considered.
