| titleOfInvention | Enhanced foam stability applications and methods |
| abstract | A method for enhancing foam stability In foaming compositions for use in oilfield treatment application, including but not limited to use in mobility control for gas flooding. The method comprises the step of adding to a foaming composition a foam stabilizer of formula (I): wherein R 1 is an alkylamido group or a branched or linear alkyl group; R 2 and R 3 are individually hydrogen or a methyl group; R 4 , R 5 and R 6 are individually hydrogen or a hydroxy group, with the proviso that at least one of R 4 ,R 5 or R 6 is a hydroxyl group; wherein the alkyl group has greater than about 10 carbon atoms. Also disclosed are methods to enhance foam stability in an aqueous foaming composition, comprising the step of adding a foam stabilizer selected from alkyl dimethyl betaine,. alkyl amidopropyl hydroxy sulfobetaine or alkyl hydroxy sulfobetaine, wherein the alkyl group has greater than 10 carbon atoms, or 12 carbon atoms or 16 carbon atoms. |
