Estimation of existing production capacity during operation in conditions of high watercut

Abstract

The paper studies the estimation of existing production capacity of the wells operated via oil well pumps in conditions of high watercut. Production parameters are of great importance during the increase of production and efficiency of using well stock, particularly, in the last stages of field development. In this view, based on the actual field data, the values of oil and water rates of the wells operated from one object have been analyzed, as well as the distribution of rates by actual watercut diapason developed. The change rate of oil and water output depending on the watercut have been calculated based on mathematical models. The research results allow specifying the limit values of watercut, as well as contribute to trustworthy prediction of oil flow rate of the wells and development by the groups and whole well stock of producing wells.
