More Information
Summary:The present invention is related to the obtaining and use of zwitterionic germinal 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.
