The present invention is related to the obtaining and using of multifunctional foaming compositions with wettability modifying, corrosion inhibitory and inhibitory/dispersants mineral scale properties with high stability in environments of high temperature, high pressure and tolerance to high concentrations of divalent ions such as calcium, magnesium, strontium and barium. The multifunctional foaming compositions are obtained from the combination of supramolecular complexes resulting from interactions of alkyl amido propyl hydroxysultaines and/or alkyl amido propyl betaines and/or alkyl hydroxysultaines and/or alkyl betaines and anionic surfactant of type alkyl hydroxyl sodium sulfonate and alkenyl sulphonates of sodium, with cationic surfactants as tetra-alkyl ammonium halides and copolymers derivatives of itaconic acid/sodium vinyl sulfonate and/or terpolymers derived from itaconic acid/sodium vinyl sulphonate/aconitic acid. These multinational foaming compositions control the gas channeling and favorably change the wettability and increase the recovery factor of crude oil in naturally fractured reservoirs of carbonate type and heterogeneous lithology. In addition to this, the multifunctional foaming compositions of this invention exhibit anti-corrosive properties in typical environments of production tubing of crude oil and antifouling/dispersants of mineral salts as calcium carbonate, calcium sulfate, barium and strontium in the reservoir and in the production and injection pipelines.

Multifunctional foaming composition with wettability modifying, corrosion inhibitory and mineral scale inhibitory/dispersants properties for high temperature and ultra high salinity

The present disclosure is related to obtaining and using sulfobetaine and hydroxysultaine-based geminal zwitterionic liquids as wettability modifiers for rocks such as limestone, dolomite, sandstone, quartz or heterogeneous lithologies, under the presence of brines having high content of divalent ions as calcium, magnesium, barium and strontium, at high temperature and high pressure conditions for enhanced oil recovery processes to increase the oil production. The geminal zwitterionic liquids of the present disclosure have also the property of acting as corrosion inhibitors of ferrous metals used in pipelines and equipment for crude oil extraction, production, transport and storage operations. A further advantage shown by zwitterionic liquids derived from their molecular structure is they can be dissolved in distilled water, brine, hydrocarbon solvents, aromatics and alcohols.

Hydroxysultaine- and sulfobetaine-based geminal zwitterionic liquids, method for obtaining same, and use thereof as wettability modifiers having corrosion inhibiting properties

The present invention is related to the obtaining and use of zwitterionic geminal liquids based on hydroxypropyl betaine, as wettability modifiers of rocks such as limestone, dolomite, sandstone, quartz or heterogeneous lithologies, in the presence of brines with high content of divalent ions as calcium, magnesium, barium and strontium, at high temperature and high pressure conditions during the application of enhanced oil recovery processes. The zwitterionic geminal liquids based hydroxypropyl betaine of the present invention have also the property of acting as inhibitors/dispersing of asphaltenes, both at extraction and production operations of petroleum industry, thus allowing to increase the level of crude oil production. An additional advantage presented by zwitterionic geminal liquid based on hydroxypropyl betaine which can be dissolved in distilled water, brine, aliphatic hydrocarbons or other polar and nonpolar solvents.

A foaming composition with wettability-modifying and corrosion inhibitory properties is used to 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 the synergistic effect resulting from the supramolecular interaction of alkyl amido propyl hydroxysultaines or alkyl hydroxysultaines with sodium alkyl hydroxysulfonates and sodium alkenyl sulfonates having the formula (1). The foaming compositions with wettability-modifying and corrosion inhibitory properties are tolerant to high concentrations of divalent ions such as calcium, magnesium, strontium and barium and are suitable for use in the reservoir, seawater and/or congenital water characteristic of the reservoir for transporting the crude oil from the reservoir.
