Abstract
This paper presents the results of applying forced fluid withdrawal (FFW) technology to enhance oil recovery in fields located in Western Siberia. The authors expand upon the classical FFW approach originally developed by A. M. Shchelkachev, V. N. Mamedov, and G. G. Sarkisyan by proposing an integration of natural gravity forces and wave effects in natural reservoirs. The analysis, which utilizes artificial intelligence methods to process geological and production data, demonstrates the high efficiency of FFW during the late stages of development in highly water-flooded wells. Using the productive sediments of the Pokamasovskoye oil field as an example, the authors can observe an increase in total oil production rate of 15 to 57% at well water-cut levels ranging from 75 to 95%. Furthermore, the project's economic efficiency improved by 15 to 30 % due to the development of low-permeability layers. The results of this study meet SPE and API standards. The researches recommend them for designing reservoir stimulation systems for other fields in Western Siberia. The proposed model's error does not exceed 5% compared to field data.
