摘要：
A method to separate a gas phase from a liquid phase in a subterranean formation that includes positioning a downhole tool in a wellbore, operating the downhole tool to form perforations in the subterranean formation in a manner that creates cyclonic motion in fluids that exit the subterranean formation and enter the wellbore through the perforations, the fluid having a gas phase and a liquid phase, and producing the liquid phase to the surface, whereby the liquid phase is substantially devoid of the gas phase as a result of the cyclonic motion.
