Abstract
The present invention is related with the obtaining process and use of branched germinal zwitterionic liquids based on either bis-N,N-dialkyl-N-polyether-betaine or bis-N, N-dialkenyl-N-polyether-betaine or bis-N, N-dicycloalkyl-N-polyether-betaine or bis-N,N-diaryl-N-polyether-betaine, to be applied as modifiers of the wettability of rocks such as limestone, dolomite, sandstone, quartz or heterogeneous lithologies, under the presence of brines having high content of divalent ions such as calcium, magnesium, barium or strontium, under high temperature and high pressure within enhanced oil recovery processes in order to increase the oil production.
