The present invention relates to the preparation of foaming formulations for high temperature, salinity and concentration of divalent ions, such as calcium and magnesium ions, that apply the synergistic effect of sodium alpha-olefin sulphonates and alkylamidopropyl betaine; said formulations may use, as solvent, water, seawater, connate water, alcohols or mixtures of all thereof. Said formulations control the piping of gas in deposits of the naturally fractured carbonate type. |
