A core flood and microfluidics investigation of nanocellulose as a chemical additive to water flooding for EOR
Aadland, Reidun Cecilie Grønfur; Akarri, Salem Saeed Fadhl; Heggset, Ellinor Bævre; Syverud, Kristin; Torsæter, Ole (Peer reviewed; Journal article, 2020)Cellulose nanocrystals (CNCs) and 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO)-oxidized cellulose nanofibrils (T-CNFs) were tested as enhanced oil recovery (EOR) agents through core floods and microfluidic experiments. ... -
Dynamic wettability alteration for combined low salinity brine injection and surfactant flooding on silica surface
Nourani, Meysam; Tichelkamp, Thomas; Hosseinzade Khanamiri, Hamid; Johansen, Trine; Hov, Ingrid Karlsen; Gawel, Bartlomiej; Torsæter, Ole; Øye, Gisle (Peer reviewed; Journal article, 2020)Experimental results of dynamic contact angle measurements of low salinity brine and combined low salinity water and surfactant flooding (LSW–SF) on silica surface are presented in this study. Dynamic contact angle experiments ... -
High-Temperature Core Flood Investigation of Nanocellulose as a Green Additive for Enhanced Oil Recovery
Aadland, Reidun Cecilie Grønfur; Jakobsen, Trygve Dagsloth; Heggset, Ellinor Bævre; Long-Sanouiller, Haili; Simon, Sebastien Charles; Paso, Kristofer Gunnar; Syverud, Kristin; Torsæter, Ole (Journal article; Peer reviewed, 2019)Recent studies have discovered a substantial viscosity increase of aqueous cellulose nanocrystal (CNC) dispersions upon heat aging at temperatures above 90 °C. This distinct change in material properties at very low ...
