A method and system for gas-lifting well effluents utilizes a porous wall in which an array of small lift-gas injection ports is present such that lift-gas is injected as an agglomerate of finely dispersed micro-bubbles into the stream of well effluents. In this way the lift-gas and produced crude oil form a froth and the risk of slugs of lift-gas that bypass slugs of crude oil and create an unstable flow regime is minimized.
