Simulation study of surfactant injection in a fractured core
Cheng, Xiaoqian; Kleppe, Jon; Torsæter, Ole (Journal article; Peer reviewed, 2019)Surfactant flooding could be used to improve water flooding in fractured reservoirs due to the main mechanisms of wettability alteration and interfacial tension reduction. However, the surfactant flooding in fractured ... -
Surfactant Enhanced Oil Recovery in Fractured Reservoirs: Simulation study of surfactant spontaneous and dynamic imbibition
Cheng, Xiaoqian (Doctoral theses at NTNU;2019:387, Doctoral thesis, 2019)Water flooding has poor performance in fractured reservoirs with mixed- or oil-wet wettability. Surfactant could be used to improve oil recovery by changing wettability to more water-wet or reducing water/oil interfacial ...
