Abstract
Aiming to optimize the total production of homogeneous gas–liquid two-phase flow in perforated vertical gas wells, a new coupled reservoir–wellbore mathematical model is proposed which consists of the crushed zone damage skin factor, pressure gradient, flow rate, and liquid holdup. An optimum strategy consisting of two optimization problems is developed to study the effect of perforation distribution on the production of vertical wells under a steady-state inflow. Then, these optimization models are applied to infinite and finite conductivity gas wells and the optimal distribution of perforation could be determined. The results show that inflow rate profiles could be improved by optimizing the perforation location for vertical gas wells.
