Sensitivity analysis of oil and gas production as a result of increasing the drainage area with changes in well parameters during different completion of wells

Abstract

Drilling of wells and their return to other horizons are planned in certain sequences and intervals in order to obtain maximum economic efficiency during the development and operation of hydrocarbon fields. It is important to determine the real layout of production wells, to study the relationship between them depending on various parameters. In the presented work, depending on the reservoir and well parameters, the drainage areas of horizontal wells and the interrelationships between these wells were determined, and the maximum final production of such wells was determined. The joint hydrodynamic model of the reservoir-well was used in the research. The results of the work can be used to determine the drainage areas depending on the angle of inclination of horizontal wells and to determine the relationship between them, to increase the economic efficiency of the field by reducing the additional costs of drilling unnecessary wells during field development.
