    Abstract: The invention relates to a method of treating a hydrocarbon containing formation, comprising the following steps: a) preparing an internal olefin sulfonate, comprising sulfonating an internal olefin into sulfonated internal olefin followed by contacting sulfonated internal olefin with a base containing solution resulting in the internal olefin sulfonate, wherein sulfonated internal olefin is contacted with the base containing solution in the presence of a non-ionic surfactant, and/or after step a) but before step b), the internal olefin sulfonate and said non-ionic surfactant are combined; b) transporting an aqueous solution comprising the internal olefin sulfonate and the non-ionic surfactant to the location of the hydrocarbon containing formation; c) providing the internal olefin sulfonate and the non-ionic surfactant to at least a portion of the hydrocarbon containing formation; and d) allowing the internal olefin sulfonate and the non-ionic surfactant to interact with the hydrocarbons in the hydrocarbon containing formation.

    Abstract: The invention relates to a process for preparing an internal olefin sulfonate, comprising sulfonating an internal olefin, having an average carbon number that is equal to or greater than 20, in a sulfonation reactor into sulfonated internal olefin followed by contacting sulfonated internal olefin with a base containing solution, wherein the sulfonation reactor is cooled with a cooling means having a temperature which is greater than 35° C. Further, the invention relates to an internal olefin sulfonate obtainable by said process, and to use of internal olefin sulfonates obtainable or obtained by said process as a surfactant, suitably as a surfactant in chemical Enhanced Oil Recovery.
