Features of the Earth’s crust structure and oil and gas potential prospects of Bolshekhetsky basin (based on reprocessing of regional seismic profiles)
Reprocessing of seismic exploration materials by regional profiles worked out in the first half of eighties of last century as well as analysis of magnetic and gravity fields allowed to establish that the known HC fields of Bolshekhetsky basin are confined to visible on seismic sections the subvertical tectonic fault zones and minimum (in most cases) potential fields. On the basis of these criteria the promising sites and objects including very large in Pre-Jurassic complex of Sredne-Messoiakhsky area have been revealed. Obtained results have scientific and applied significance and allow to optimize process of new fields exploration both in Cretaceous deposits and deep-occurring horizons.
