The present invention relates to obtaining and using foaming compositions with wettability-modifying and corrosion inhibitory properties that control the channeling of fluids in naturally fractured carbonate reservoirs, favorably alter the rock wettability in crude oil enhanced recovery processes and control uniform corrosion problems occurring in production rigs under high temperature and ultra-high salinity conditions; by means of the synergistic effect resulting from the supramolecular interaction of alkyl amido propyl hydroxysultaines or alkyl hydroxysultaines with sodium alkyl hydroxysulfonates and sodium alkenyl sulfonates (1). The foaming compositions with wettability-modifying and corrosion inhibitory properties are characterized for being tolerant to high concentrations of divalent ions such as calcium, magnesium, strontium and barium and for the fact that for their application in the reservoir, seawater and/or congenital water characteristic of the reservoir may be used as m eans of transportation.
