METHOD FOR OIL RESERVOIR DEVELOPMENT Russian patent published in 2022 - IPC E21B43/30 

FIELD: oil industry.

SUBSTANCE: invention relates to a method for developing an oil deposit. The method is applicable in the formation of a system for the development of small and medium deposits. The method is implemented through the use of an irregular grid of wells. The irregular grid of wells makes it possible to take into account the individual features of the geological structure of the production facility. The optimal parameters of the development system, such as the total number of wells, the number of drilled wells per year, and the amount of reserves involved in development, are preliminarily determined by the limiting values ​​of oil recovery factor and NPV. The method includes the steps of modeling and forecasting. The modeling stage consists in building a hydrodynamic model of the field based on the data obtained during the drilling of exploration wells. The hydrodynamic model of the field includes a map of the state of wells, a map of mobile reserves, maps of reservoir pressures, maps of reservoir fluid filtration rates. The prediction stage includes the application of a computational procedure to optimize well placement.

EFFECT: ensuring the possibility of increasing the oil recovery factor.
