The article presents the results of a differentiated probabilistic multi-criteria assessment of the prospects for oil and gas potential of the Lower Middle Jurassic and pre-Jurassic deposits for 47 promising objects located in the north of Western Siberia.
Materials and methods
Geological and geochemical materials were used for 47 deposits located in the north of the West Siberian oil and gas province: data on the structure of the study area of the section and the lithofacies composition of the section, data on the FES filtration-volumetric
parameters of reservoir rocks, as well as geochemical indicators such as TOC (%), stage of catagenesis, intensity emigration of liquid hydrocarbons (thousand tons/km²), intensity of generation of gaseous hydrocarbons (thousand m³/km²). The method of quantitative (probabilistic) assessment of the oil and gas potential of poorly studied lower- middle jurassic Jurassic and pre-Jurassic deposits based on the use of several geological and geochemical parameters has been applied.
