Assessing oil recovery rates through geological and hydrodynamic modeling incurs significant financial time investments. Consequently, recalculations of recoverable hydrocarbon reserves occur infrequently, leading to potential discrepancies between approved factors actual conditions. To ensure accuracy in assessing residual reserves, it's crucial promptly monitor the validity factors, especially concerning their achievability within specific timeframes. This article examines practice annually economic according international standards. Operational monitoring methods include analog-statistical techniques, displacement characteristics, production decline rate analysis, each reliant on initial data quality object development stages. The effectiveness these is illustrated examples. Analog-statistical dependencies, tailored operational facilities' indicators, prove most effective for early-stage development. In advanced stages, based characteristics gain reliability, factoring profitability limits. Statistical dependencies incorporating technological indicators can enhance control measures. Integrating diverse methodological approaches ensures a more dependable assessment reserves. When determining designing fields, main characteristic that determines reliability forecast calculations estimating factor. value factor characterizes share be extracted from subsoil when developing deposit using modern proven technology techniques limit while complying with requirements environmental protection. common method digital geological-hydrodynamic modeling, which processes occurring during deposits are simulated software. has been introduced Russian industry since mid-90s.
