Title

WETTABILITY ALTERATION AROUND THE WELLBORE IN GAS CONDENSATE RESERVOIRS TO AVOID CONDENSATE BANKING

Pages

  67-75

Abstract

 The productivity of condensate-gas reservoirs can be adversely affected by accumulation of condensate near the wellbore when the pressure decreases below the dew point. One of the proposed methods to prevent this condensate banking is altering rock WETTABILITY from liquid-wetting to gas-wetting by appropriate chemical treatment. We evaluated the performance of this treatment process for a real well by single well SIMULATION study. The effect of RELATIVE PERMEABILITY modification on the residual oil saturation in the region 1 around the well, total condensate production and total gas production were studied in our SIMULATION work. The effect of chemical treatment up to different radial distances from the wellbore on total gas and condensate production were compared. The results showed short distance treatment around the well may be sufficient to prevent condensate accumulation near the wellbore. The economic analyses showed that the WETTABILITY alteration can increase gas production revenue. The results of the present work demonstrated that the chemical treatment can be economically applied in the field scales.
