Analysis of vertical well performance considering a new understanding of geological structure
I.V. Davletshina - Institute “TatNIPIneft” of PJSC “Tatneft” named after V.D. Shashin, Almetyevsk, Russia,The largest oil fields in the Republic of Tatarstan, along with a number of fields in Azerbaijan and other oil-producing regions, are currently at a late stage of development, which increases the urgency of maintaining existing hydrocarbon production levels. One of the key strategies to address this challenge is the development of hard-to-recover reserves. In the Volga-Ural region and oil-producing areas of Azerbaijan, particular attention is given to carbonate reservoirs of the Lower and Middle Carboniferous, which account for approximately one-third of the recoverable oil reserves. The geological structure of these reservoirs differs significantly from that of terrigenous collectors, necessitating further studies and the development and implementation of new, unconventional methods. The implementation of these measures will improve the development system for carbonate fields. This paper analyzes the performance dynamics of vertical wells, taking into account the geological features of the reservoirs, and proposes recommendations for optimizing field development.
