| titleOfInvention | Viscosity and phase separation control additives for foaming alkyl aromatic sulfonates |
| abstract | ABSTRACT A foaming surfactant concentrate useful in enhanced oil recovery with improved stability and flowability. This concentrate comprises water, greater than 12 wt % of a C20-30 alkyl aromatic sulfonate component having an average molecular weight from about 460 to about 600, a mixture of organic additives comprising a viscosity-reducing hydrotrope and a dispersant comprising a nonionic surfactant, and optionally a polymeric nonionic surfactant. The amount of organic additives is less than 50 wt % of the weight of the C20-30 alkyl aromatic sulfonate. |
