Mineralogical alterations in calcite powder flooded with MgCl2 to study Enhanced Oil Recovery (EOR) mechanisms at pore scale
Minde, Mona Wetrhus; Madland, Merete Vadla; Zimmermann, Udo; Egeland, Nina; Korsnes, Reidar Inge; Nakamura, Eizo; Kobayashi, Katsura; Ota, Tsutomu (Peer reviewed; Journal article, 2019)Seawater injection into chalk-reservoirs on the Norwegian Continental Shelf has increased the oil recovery and reduced seabed subsidence, but not eliminated it. Therefore, understanding rock–fluid interactions is paramount ... -
Raman spectroscopy applied to enhanced oil recovery research
Egeland, Nina (Master thesis, 2015-06-09)It is well established that aqueous chemistry affects the mechanical strength of chalk. Seawater tends to weaken chalk at reservoir temperatures and consequently the recovery rate. As more than 50 % of the oil in existing ...
