Billy W Surles, Philip D Fader, Carlos W Pardo: Formation treating. Texaco, James L Bailey, Jack H Park, April 6, 1993: US05199490 (92 worldwide citation)

Disclosed are processes for treating a subterranean formation to improve the permeability distribution by reducing the permeability in high permeability zones, so fluids injected for oil recovery purposes will sweep more uniformly through the formation. The processes involve injecting a polymerizabl ...
