In this paper, we consider the technology of geological modeling of oil and gas reservoirs, based on the results of interpretation of the mud logging and well logging data. Informative geological and geophysical parameters for distinguishing marking horizons were determined. A technological scheme for opening productive reservoirs is proposed, based on the allocation of reference layers of different levels.

In this article, a lithologic-petrophysical model of oil and gas bearing carbonate reservoirs of the Severo-Limanskoye oil field is considered. Geological and geophysical characteristics of carbonate reservoirs are determined. A detailed lithologic-stratigraphic description of the marking horizons is given. Geological models of reservoir of the Dankovian-Lebedyanian sediments and the Zavolzhskian-Malevkian sediments of the Severo- Limanskoye oil field are complied.

In this article, a lithologic-petrophysical model of oil and gas bearing terigenic reservoirs of the Severo-Limanskoye oil field has been considered. Geological and geophysical characteristics of terigenic reservoirs have been determined. Lithologic-petrophysical models of reservoir of the Tula-Bobrikov sediments and the Alexin sediments of the Severo-Limanskoye oil field have been compiled. The regularity of the change in reservoir properties (porosity, effective thickness of beds) vertically and laterally in the reservoirs has been traced.
