  • Composition of an organic foaming additive for high temperature and high salinity
    Patent number: 10457863
    Abstract: The present invention refers to the formulation of a foaming agent for extreme conditions of salinity, temperature and concentration of divalent ions, including the improvement in the performance in these conditions with respect to the patent MX2008015989 A. Also, the design is presented of the experimental equipment used to characterize and evaluate foaming agents at laboratory level and conditions of pressure, temperature and salinity, in oil fields. The formulation of the foaming agent derived from this invention is a mixture of sodium alpha olefin sulfonates, alkylamido propyl betaines and triethanolamine, capable of giving it the benefit of being stable in temperature and salinity in a wide range, diluted in synthetic and congenital brines. This formulation is applicable for the control of gas mobility and improved oil recovery processes in naturally fractured reservoirs.
