The article presents the results of the analysis of the geophysical survey coverage (profiles and wells) performed during the implementation of the quantitative assessment of HC-resources of the Russian Federation. We analyzed the current state of digital cartographic data, representing profiles and wells location, and identified the main problems that seriously complicate the practical use of such data. An original technological approach is proposed, which allows to calculate the formalized density indicators for the analyzed territory even in the conditions of the low quality of cartographic data. The implementation of the proposed approach was carried out by the authors of the article in the GIS INTEGRO. In conclusion, attention is focused on the need to change the existing scheme of conducting geological and geophysical studies to ensure its effective use for geological studies.
