Type: article
Abstract: Background. The areas of work on the selection and recommendations for the deployment of the effective types of research in hydrocarbon exploration are relevant, because the identified regularities provide the possibility of forecasting oil and gas accumulations in the megareservoirs of sedimentary deposits, which contributes to the increase of the resource base of the region. Objective. Analysis and systematization of the relationship of the main parameters of the deposit, such as effective reservoir volume and reservoir properties – permeability and porosity – with the value of geological reserves, as well as the development of methodological guidelines for the program of the research types. Materials and methods. Geological and field characteristics of the deposits of the Mesozoic oil and gas complexes of Western Siberia: porosity and permeability of reservoir rocks; their effective volume; balance hydrocarbon reserves in 2022. Statistical analysis of the peculiarities of the relationship between geological parameters of the deposits and the scale of the deposits for each complex; interpretation of the Rock-Eval analysis data. Results. The research on the assessment of the geochemical features and the scale of hydrocarbon accumulations in the Mesozoic oil and gas complexes of the northern regions of the West Siberian oil and gas basin is summarized. The relations of geological reserves of deposits with tectonic, paleofacial and geochemical features of sediments, as well as with the main reservoir characteristics are revealed. The prospective objects are evaluated on the basis of geochemical studies and considering the data on the scale of hydrocarbon accumulations. Conclusions. Prospects for detection of megareservoir accumulations of hydrocarbons and the most productive types of research can be assessed on the basis of the established dependencies.
