Abstract

This article presents the interpretation results of the geophysical methods for well research and field development monitoring of PJSC “Tatneft”. According to the presented results, the structures of fields are characterized by different mining and geological conditions, multiphase saturation of reservoirs, etc. For this reason, the paper considers the interpretation results of the investigated method for various conditions. Based on the results of the work, the authors managed to increase the reliability of the current oil saturation assessment, which consequently made a positive contribution to the increase in oil reserves at the late stage of field development. On the basis of the results of the carbon-oxygen logging interpretation, authors present examples for determination of the WOC position, the material composition of rocks, and the type of saturation for layers of various mineralization.

The relevance of this article is not in doubt, since at the late stage of development, detailing the geological structure in order to search for missed oil deposits and effective technologies for development of oil reserves is an urgent and desired task. One of the geophysical methods that allows us to assess the current of oil saturation and build a lithological model of the reservoir is carbon-oxygen logging.

Key words:

carbon-oxygen logging (C / O logging), reservoir, oil saturation, interpretation, oil, wells, geophysical parameters
