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 ... -
Interactions between Surfactants and Cellulose Nanofibrils for Enhanced Oil Recovery
Jakobsen, Trygve Dagsloth; Simon, Sebastien Charles; Heggset, Ellinor Bævre; Syverud, Kristin; Paso, Kristofer Gunnar (Journal article; Peer reviewed, 2018)Chemical enhanced oil recovery (EOR) represents a series of potential solutions for extracting more oil from resources with already known locations and magnitudes. Unfortunately, many of the chemical additives in use today ... -
SAPO-34 with Copper: Investigation of hierarchical pore characteristics and interactions with copper for catalytic applications
Jakobsen, Trygve Dagsloth (Master thesis, 2014)Hierarchical SAPO-34 was produced using the dry gel conversion method, where an amorphous, mesoporous silicoaluminophosphate was subjected to steam treatment with the presence of organic template. This resulted in a ...
