Reactive transport modelling of hydrate phase transition dynamics in porous media
Vafaei, Mohammad Taghi (Doctoral thesis, 2015-03-27)Gas hydrate is believed to be so abundant in nature that some estimates suggest it contains more than two times equivalent energy of the whole fossil fuels on Earth. Besides, reservoir hydrates have other important aspects ... -
Simulation of geomechanical effects of CO2 injection in cold aquifers with possibility of hydrate formation
Kvamme, Bjørn; Jemai, Khaled; Chejara, Ashok; Vafaei, Mohammad Taghi (Chapter; Peer reviewed, 2011)The injection of CO2 in saline aquifers can have a significant impact on the geochemistry and the geo-mechanics of the reservoirs. Due to this injection, minerals will dissociate in regions with low pH or precipitate in ... -
Simulation of hydrate dynamics in reservoirs
Kvamme, Bjørn; Vafaei, Mohammad Taghi; Chejara, Ashok; Jemai, Khaled (Chapter; Peer reviewed, 2011)Gas hydrates in reservoirs are generally not in thermodynamic equilibrium and there may be several competing phase transitions involving hydrate. Formation of carbon dioxide hydrates during aquifer storage of carbon dioxide ... -
Theoretical studies of CO2 hydrates formation and dissociation in cold aquifers using RetrasoCodeBright simulator
Jemai, Khaled; Kvamme, Bjørn; Vafaei, Mohammad Taghi (Peer reviewed; Journal article, 2014)Abstract: - Hydrates of CO2 and water can form during aquifer storage if the reservoir has regions where conditions of pressure and temperature are inside the hydrate forming conditions. A very common assumption is that ... -
Theoretical studies of Methane Hydrate Dissociation in porous media using RetrasoCodeBright simulator
Chejara, Ashok; Kvamme, Bjørn; Vafaei, Mohammad Taghi; Jemai, Khaled (Peer reviewed; Journal article, 2012)Methane hydrates in reservoir are generally not in chemical equilibrium, there may be several competing hydrate phase transitions like for instance hydrate dissociation due to pressure or temperature changes, hydrate ...
