Consideration of the processes of oil deposit reformation during long-term operation and deep feeding in modeling the development of oil fields

Abstract

The article is devoted to the study of replenishment of oil reserves in long-developed fields and contains a substantiation of the need for its monitoring and control. This will allow for a new approach to modeling the development and evaluation of residual reserves in the late stages of development of oil fields. In order to identify the conditions for the reformation of the deposits, special geochemical studies should be organized to localize the replenishment sites, as well as geological and commercial studies to determine the rate of oil accumulation in the trunks of highly watered wells. These works will allow selecting the most promising areas of the deposit to search for channels for deep degassing of hydrocarbons and recommending carrying out seismic studies with new innovative technologies for mapping channels and subsequent monitoring of degassing processes. The newly obtained results, combined with the information already available, will allow us to take a new approach to the development of an alternative geological and hydrodynamic model that will determine the rates of reservoir regeneration during development and the volumes of hydrocarbon reservoirs from the depths. It will also help to predict the role of reformation processes in the total oil production.
