Construction of geological model of a shallow super-viscous oil deposit based on core analyses and geophysical monitoring data

© Published under licence by IOP Publishing Ltd. Deficiency of fossil minerals, limited reserves of conventional hydrocarbon raw materials indicates the need to involve in the fuel and energy complex of other sources of hydrocarbons. Fields of super-viscous oil are one of the sources. Development of super-viscous oil deposits opens new challenges in the field of building geological models associated with the shallow occurrence of these deposits. This article is devoted to the study of sediments of the Permian sedimentary complex containing super-viscous oil deposits. Study object is Sheshmian sandstone pack of the Ufimian stage. The pack is composed of sands and sandstones with different degree of carbonate cementation with small interlayers of siltstones. Cementation is the main factor which affect reservoir quality. In the process of analysis and preparation of the initial data and, subsequently, the geological model construction, the main features of the super-viscous oil deposits were revealed.
