STRUCTURAL FEATURES OF THE EARTH'S CRUST AND PETROLEUM POTENTIAL: FIRST RESULTS OF CMP DEEP SEISMIC SURVEY ALONG THE GEOTRAVERSE ACROSS THE VOLGA-URAL PETROLIFEROUS PROVINCE

Abstract

Deep CMP seismic surveys carried out in petroliferous regions of Tatarstan (since 1993) and other regions of the Volga–Ural petroliferous province in the later period revealed that time sections of large oil fields are underlain by intense dynamic anomalies. Although the nature of these anomalies is unclear, their presence has demonstrated the principle possibility to elaborate methods for predicting large hydrocarbon fields based on the CMP method. The above fact simulated similar seismic studies in the Kirov, Samara, Orenburg, Bashkir, and Udmurt regions, as well as prospecting in Tatarstan.
