Method for controlling permeability of subterranean formations
Patent
·
OSTI ID:5778680
In the recovery of hydrocarbon materials from subterranean formations, the simultaneous production or loss of other fluids such as water is inhibited by the selective introduction into the subterranean porous structure of discrete spheroidal microgels of a water-swollen or water-swellable, crosslinked polymer such as crosslinked polyacrylamide.
