Description

The surface active agents employed in surfactant waterflooding processes are usually of the alkylaromatic type and most commonly petroleum sulfonates. These surfactants, under appropriate conditions, are capable of lowering the oil-water interfacial tension and of mobilizing tertiary oil; their chief drawback is their sensitivity towards saline waters in general and divalent cations in particular. This paper examines the stability of imidosulfonate surfactants and attempts to provide an estimate of their useful lifetimes under typical field conditions. (EN)
