Abstract
Methods for stabilizing a formation containing water sensitive materials include forming a composition including at least one amido-amine based cationic gemini surfactant and treating the water sensitive materials with an effective amount of the composition.
Claims18
A method for stabilizing a formation containing water sensitive materials comprising:
- forming a composition comprising at least one amido-amine based cationic gemini surfactant having Formula I:
- wherein n is 2-36;
- Q is an alkyl group having 1-10 carbon atoms, an aromatic group, or an aliphatic group, and includes one or more of Si, S, and N;
- R1 and R2 are each alkyl groups having 1-5 carbon atoms;
- and X is F, Cl, Br, or I;
- and
- treating the water sensitive materials with an amount of the composition effective to stabilize the water sensitive materials.
