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. ... -
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 ...
