A method for predicting the on-set of sand production or critical drawdown pressure (CDP) in high flow rate gas wells. The method describes the perforation and open-hole cavity stability incorporating both rock and fluid mechanics fundamentals. The pore pressure gradient is calculated using the non- ...
