Modeling of wells overhaul period on the base of operating practices data

It is known that Azerbaijanian onshore oil and gas fields are developed on the late stages. These fields are characterized by depletion of production objects, pressure drop, gradual decreasing of production and overhaul period, increasing of water cutting of production and etc. For the purpose of efficiently development and recovery finish it is necessary the activities for optimization operating practices, increasing of wells overhaul period, limiting of water cutting and etc. In connection with this and using actual production data of Sabunchu-Balakhany-Romany oilfield, mathematical experiments for increasing overhaul period have been carried out. On the base of correlation-regression analysis regression equations have been obtained. These equations connected the overhaul values with all considered operational aspects. Estimated calculations on the base of obtained equations show the increasing of overhaul values in according with appropriate operation parameters. Thus research results realized on the base of production date of considered oilfield provide possibilities for taking a decision in purpose of optimal control of wells overhaul.
