ABSTRACT:
A method for the disposal of waste water in a formation having varying permeability zones therein where a higher permeability zone is first closed to fluid flow via a solidifiable gellable mixture. This mixture forms a solid gel in the higher permeability zone. Afterwards, waste water is injected into a zone of lesser permeability which allows increased amounts of water to be placed into the formation.
