In this study, we first present the effect of low gas and liquid velocities on steady-state nitrogen foam properties with Alpha Olefin sulfonate C14-16 at 300 psi and ambient temperature. The same sandpack was used for all foam core flood experiments in order to preserve...

... rate while increasing the superficial liquid velocity does not significantly increase erosion. Increased viscosity decreases the impacting velocity of impinging particles, and thereby reducing the magnitude of erosion on the pipe wall. The affect of particle size has been investigated and found to vary...

Methods to deal with this situation include downhole gas separators and locating the pump below the producing interval to allow gravity to effectively separate the gas from the liquid. High liquid velocities can drag excessive amounts of gas downward which degrades pump efficiency...
