ABSTRACT:
A well treating solution is shown for changing the relative permeability of a formation being treated to water. The solution is made by mixing an amphoteric polymeric material, a mutual solvent and a surface active agent in a brine carrier liquid. The well treating solution is injected into the formation at pump rates below the fracture gradient of the formation. The well is briefly shut-in, after which production can be resumed. The treating solution and method taught lower the permeability of the producing formation to water without substantially affecting the formation's permeability to oil and gas.
