Water based foaming composition - method for making same |
| abstract |
The invention concerns a water based foaming composition and the method for making it. The composition is optimised in that it contains a surfactant specifically selected according to the polymer also present in the composition. the surfactant and the polymer are selected such that they are oppositely charged. The invention is very useful in drilling or treating wells. |
