Condensate blockage study in gas condensate reservoir

• The effect of condensate blockage on the pressure drop near the well bore is studied.
• Two types of single well simulations have been conducted.
• Pressure drop is quantified based on variation of gas relative permeabilities in near well bore area.
• The relationship of condensate banking pressure drop, gas rate and reservoir quality is presented.
• Condensate blockage can increase the pressure drop to 200% of the pressure drop in the tubing for a poor reservoir quality.

The effect of condensate blockage on the pressure drop near the well bore has been studied. Two types of single well simulations have been conducted and pressure drop due to condensate blockage has been quantified based on variation of gas relative permeabilities in near well bore area. The relationship of condensate banking pressure drop, gas rate and reservoir quality has been presented. It is shown that for a poor reservoir quality, condensate blockage can increase the pressure drop up to 200% of the pressure drop in the tubing.
