12/10/2017, · Foam fracturing fluid is actually a liquid-in-gas emulsion, usually composed of the vapor and liquid. Gas is added to water-based or oil-based liquid to form a relatively stable gas-liquid two-phase substance as a fracturing fluid. It contains compressed air foam (usually CO 2 or N 2) with a volume fraction up to 90%.

16/4/2020, · Foam-,fluid, densities can be substantially less than those of water-based fluids. In low-pressure reservoirs, low-density fluids, like foam, can be used to assist in the ,fluid, cleanup. Conversely, in certain deep reservoirs (including offshore frac-pack applications), there is a need for higher density ,fracturing, fluids whose densities can span up to > 12ppg.

Reducing the water content of the ,fracturing, media minimizes this type of damage. Another benefit is that after ,fracturing,, the compressed gas in the foam expands and helps to rapidly unload the ,fracturing fluid, from the well. Studies have shown that wells fractured with foam clean up faster than wells treated with gelled aqueous fluids.
