Alfred R Jennings Jr: Disposal of produced formation fines during oil recovery. Mobil Oil Corporation, Alexander J McKillop, Michael G Gilman, Charles A Malone, November 29, 1988: US04787452 (242 worldwide citation)

Recovered formation fines are pumped in slurry form into an injection well during an enhanced oil recovery process e.g. a steam flood. Said injection can be done incrementally in stages in conjunction with said process. Said fines improve the sweep efficiency of the injected medium. This method is a ...
