Developing stable foams from polymeric surfactants for water production control
This research explores a new method using foams for water production control in an oilfield. Reducing water production during oil production is an important objective impacting the profitability of a mature oilfield. ...
Surfactant-enhanced oil recovery process for a fractured, oil-wet carbonate reservoir
Oil recovery by water flooding is usually not effective because of capillary forces in fractured, oil-wet carbonate formations. Sodium carbonate/surfactant solution was used to enhance spontaneous imbibition between the ...
