CO2 Injection in Hydrate Bearing Sandstone with Excess Water
(Master thesis, 2013-05-31)It has previously been shown that methane can be produced from gas hydrates by exposing it to carbon dioxide. Since CO2 is the preferred hydrate former below 10 °C it will spontaneously replace CH4 as the guest molecule ... -
Condensation of water on rust surfaces, and possible implications for hydrate formation in pipelines
(Master thesis, 2011-06-01)The threat of climate change has put the spotlight on the increase in carbon emissions and possible methods to attenuate it. As a consequence of this, oil and gas companies have started to consider both how to reduce ... -
The effect of calcite minerale on hydrate stability and CO2 adsorption
(Master thesis, 2011-06-01)The background for conducting this study are the huge unused possibilities for storage of large quantities of the greenhouse gas carbon dioxide in old or depleted oil reservoirs or deep brackish aquifers. The method of ... -
Enthalpies of CH4 and CO2 Hydrate Formation and Dissociation Using Residual Thermodynamics
(Master thesis, 2019-11-27)The problem in the processing industries regarding the formation of gas hydrate in pipelines or equipment have inspired much of the research for better understanding of hydrates. The world’s increasing demands for more ... -
Hydrate formation and CO2 - CH4 exchange in sandstone - An experimental study with emphasis on the role of initial brine saturation and salinity
(Master thesis, 2013-06-01)Recent research activity has demonstrated the viability of producing methane from gas hydrate bearing sediments by injecting and sequestering CO2 in a process where CO2 replace methane in gas hydrate by a process called ... -
New Concept for Evaluating the Risk of Hydrate Formation during Processing and Transport of Hydrocarbons
(Master thesis, 2017-10-31)Transport of hydrocarbons from reservoir to gas processing plants and for supply to delivery terminals is predominantly done using pipelines, particularly within reasonable distance. In the North Sea of Norway, there are ... -
Numerical simulations of the flow and plugging behaviour of hydrate particles
(Master thesis, 2010-05-06)Abstract The main hydrate mitigation used by the industry today is to avoid formation at all cost. Avoidance of hydrate formation is made possible by use of inhibitors such as methanol or glycol. These are so called ... -
Phase field theory modeling of CH4/CO2 gas hydrates in gravity fields
(Peer reviewed; Journal article, 2011)Natural gas hydrates in reservoirs are thermodynamically unstable due to the interactions with surrounding fluids (aqueous, gas) and mineral surfaces. Depending on the local flow hydrate will dissociate as well as reform. ...
