ABSTRACT:
A method for selectively closing pores in a zone of greater permeability in a formation for profile control. A rehealable Xanthan biopolymer is combined with a crosslinked non-selective polyacrylamide polymer gel. The combined gel system is injected into a formation where the Xanthan biopolymer gel selectively enters a zone of greater permeability carrying therewith said non-slective gel. Once in the formation's zone of greater permeability, the gel reheals and forms a rigid gel with substantially better temperature stability.
