Figure 17. Relative gas mobility as a function of gas velocity at zero liquid rate, of foams generated by coinjection in 29- and 10-darcy bead packs (40) and in the pressure-driven mode in 8-darcy bead packs ("13, 20, 25).

Figure 19 shows experimental gas-blockage data for some model foam systems (31). Foams were generated in pressure-driven displacements of surfactant solution by gas. A gas-blocking state was reached with only gas entering and exiting the pack. At this state, the pressure drop was increased in steps and the stabilized Qg and AP were measured at each successive gas-blocking state. In the present context, the data are... [Pg.345]
