Abstract

Today, the share of high-viscosity oil and natural bitumen in explored reserves is growing very rapidly and, thus, the volume of production of this unconventional hydrocarbons is growing. World oil reserves amount to about 320 billion tons of heavy oils and bitumen, mainly concentrated in Canada and Venezuela. More regarding the amount of bitumen reserves, is the territory of the Volga-Ural province, where the concentration ranges between 4.7 to 18 billion tons. The wide development of high-viscosity oil and natural bitumen deposits opens new challenges in the field of building geological models associated with the shallow occurrence of these deposits and the inability to use seismic data as the basis for creating a model. This article considers the geological structure of the Lower Kazan and Ufa deposits. Geological modeling of a shallow super-viscous oil deposit on the basis of litho-technological types of rocks of the productive complex using drilling, core and logging data was carried out. Questions regarding constructing a structural framework of a three-dimensional grid, a litho-technological model, describing the distribution of the parameters of porosity and permeability, oil saturation, and the justification of the bottom boundary of the deposit are considered.
