Комплексирование методов потенциальных полей, сейсморазведки и бурения для прогноза гипергенных коллекторов доюрского основания

Paleozoic complex within the West Siberian basin is considered as a hydrocarbon prospective object. It is known that supergene reservoir of upper part of Paleozoic basement can contain fluids. In this article an integrated approach to the supergene reservoir detection and mapping is described. Firstly gravity and magnetic exploration data was used to work out a structural model of the Central Uvat region. Then core data was used to connect potential field data and lithological composition of the basement rocks. Also seismic attributes and seismic facies analysis were involved to detect fracture zones in the upper part of the basement and define shapes of geological bodies. Combining all the data potential reservoir rocks of the upper part of the basement were mapped
