摘要
The utility of cosurfactant stabilization was demonstrated in linear, two-phase flow tests through tight, unconsolidated sandpacks involving brine and gas. A solution containing 0. 45% Alipal CD-128 and 0. 05% Monamid 150-AD can decrease gas mobility over 100-fold. The effect appears to be time-independent, indicative of good foam stability. Alipal CD-128 alone reduces gas mobility even more, usually by a factor of two. The moderating influence of a cosurfactant could be beneficial in avoiding 'overcontrol' of mobility, especially in low-permeability reservoirs.
