A first solution containing a nitrogen-containing compound and a second solution containing a nitrite-containing compound are introduced into the water-bearing formation. The two solutions intermix within the formation such that a foam is generated within the formation.
Claims20
A method for remediation of a water-bearing formation comprising the steps of:
- introducing into the first aqueous solution and a second aqueous solution into the water-bearing formation such that the first aqueous solution and the second aqueous solution intermix within the water-bearing formation;
- and
- maintaining the intermixed solution in the water-bearing formation such that a foam is generated in situ;
- where the intermixed solution comprises a foaming agent;
- where the first aqueous solution comprises a nitrogen-containing compound;
- and
- where the second aqueous solution comprises a nitrite-containing compound.
