Calculation ofCumulative Water Influx Using Van-Everdingen Model with superposition concept by MATLAB program

Abstract

Natural influx of water in oil reservoir surrounded by water aquifers play a very important role in increasing oil recovery. Such reservoir caused by production of hydrocarbon promotes the influx of water from surrounding aquifer to offset it. this can drive more hydrocarbons towards the surface thus enhancing the oil recovery. In this research a computer program has been designed based on dimensionless solution of diffusivity equation (Everdingen(, The program has been validated with good resultsobtained. In addition to that a cumulative water influx for x field has been calculated to reflect the validation of the program.
