... for (a) 1 cP liquid and (b) 6 cP liquid viscosities (data from Fore and Dukler 1995 ) The increase in liquid viscosity resists the external disruptive forces from the flowing gas phase and strengthens the droplet stability, which in turn leads to larger droplet sizes as shown in Fig. 1 for liquids...

... in field life. Moderate oil viscosity (10-16 cp), high initial oil saturation (90-95%), low reservoir temperature (65-69 deg C), low formation water salinity (<8000 ppm NaCl equivalent), high porosity (25%) and high permeability (2-10 Darcies) make it a very suitable candidate for polymer injection...

... the lowest possible settling velocity, which in turn lead to the highest possible velocity factor. Foams consist of a base fluid such as water (external phase), a gas (internal phase) and a stabilizing surfactant (foaming agent) to maintain stable foam for a longer period. The viscosity of the foam...
