A method for assessing the effectiveness of water isolation works based on the development of a hydrodynamic model

Abstract

An important task at the stage of designing any activity related to oil recovery enhancement (in the present case repair and isolation works), is process modeling, in particular, hydrodynamic modeling. Modeling is used to forecast the parameters of oil recovery as s function of the implemented technology at the design stage. As a result, the cost of works performed can be reduced and the profitability and success rate of the planned activities can be assessed. The paper considers the assessment of technological and economic effects using the developed two-phase hydrodynamic model simulating oil-saturated and water-bearing layers. Discussed are the calculated values and relationship between skin factor and various isolation factors. The graphs of oil flow rate and water cut as functions of the material isolation factor are given. Keywords: water isolation; hydrodynamic model; skin factor; isolation factor; water inflow.
