Key words: pre-Jurassic rocks, Western Siberia, geodynamic environment, oil and gas content
To study the pre-Jurassic basement the systemic scientific-research and pilot projects were carried out at Rogozhnikovskoye field. Reasonable classification of rocks is executed, petro-types, most of which are reservoirs with different oil saturation, are selected. Initial conception about the pre-Jurassic basement of Rogozhnikovskoye license site is substantially changed. A substantial body of information, indicating the formation of volcanogenic complex in conditions of the continental margin, is accumulated.
