Empirical and Numerical Evaluation of Mechanisms in Gas Production from CH4-Hydrates: Emphasis on Kinetics, Electrical Resistivity, Depressurization and CO2-CH4 Exchange
Birkedal, Knut Arne (Doctoral thesis, 2013-12-13)Focus is shifted towards renewable energy and sources of natural gas as the demand for cleaner energy continues to increase with global awareness on anthropogenic climate change. Methane (CH4) provides advantages such as ... -
Hydrate Formation and CH4 Production from Natural Gas Hydrates - Emphasis on Boundary Conditions and Production Methods
Birkedal, Knut Arne (Master thesis, 2009-05-13)Natural gas hydrate is a solid state of gas and water at low temperature and high pressure. Gas hydrates are known to form hydrate plugs in production line, and has thus generally been considered a problem to the oil ... -
Transport mechanisms for CO2-CH4 exchange and safe CO2 storage in hydrate-bearing sandstone
Birkedal, Knut Arne; Hauge, Lars Petter; Graue, Arne; Ersland, Geir (Peer reviewed; Journal article, 2015-06-08)CO2 injection in hydrate-bearing sediments induces methane (CH4) production while benefitting from CO2 storage, as demonstrated in both core and field scale studies. CH4 hydrates have been formed repeatedly in partially ...
