Much More than k
Reservoir Sweep Improvement
Fluids, Cores, and Flooding Procedures
Imbibition and Drainage before Gel Placement
Water Imbibition into Berea
Connectivity of Phases before Gel Placement
Oil and Water Flooding after Gel Placement
Water Drainage from Berea: Oil Injection Reduced Gel Volume.
Water Drainage from Berea
in Berea Was Higher after Gel Placement than before
Water Imbibition into Berea: Oil Was Trapped
Oil Imbibition into Polyethylene: Reduction of Gel Volume Occurred Mainly in Small Pores.
Connectivity of Phases after Gel Placement.
