Acoustic Signatures of Gas Hydrates - Observations and Modelling
(Master thesis, 2017-08-08)Interpretation of a Bottom Simulating Reflector (BSR) associated with gas hydrate accumulations in seismic, depend on gas hydrate saturation and distribution in pore voids. The BSR cannot predict gas hydrate saturation or ... -
“An Experimental Study of Bulk Foam Properties with Commercial Surfactants in Saline Environments”
(Master thesis, 2019-06-22)Foam is a fascinating two-phase phenomenon with a wide range of different industrial applications; contaminated-aquifer remediation, separation of waste-waters, enhanced oil recovery, gas leakage prevention and matrix-acidizing ... -
Application of MRI in studies of tetrahydrofuran hydrates in quartz sand at atmospheric pressure
(Master thesis, 2017-12-06)Natural gas hydrates form under low temperatures and high pressures. They can be found in abundance in permafrost environments and under the sea floor, where the temperature and pressure conditions ensure their stability. ... -
Carbonate rock dissolution during CO2 and brine injection – An experimental study applying in-situ imaging by PET and CT
(Master thesis, 2021-03-01)Carbon Capture and Storage (CCS); capture of CO2 from point sources followed by permanent storage in subsurface geological formations; can contribute to mitigating anthropogenic CO2 emissions, and to the ongoing energy ... -
Catalysts for Enhanced CO2-CH4 Exchange in Natural Gas Hydrates. An experimental feasibility study of exchange enhancement by use of chemical additives
(Master thesis, 2013-06-01)Gas hydrate is a solid state of gas and water at high pressure and low temperature conditions. Vast energy potential is associated with gas hydrates and extensive on-going research aims at addressing the technical viability ... -
Characterization of Associating Polymer (AP) Solutions. Influences on flow behavior by the degree of hydrophobicity and salinity
(Master thesis, 2013-06-02)The most applied polymer today for chemical improved oil recovery (IOR) processes, such as polymer flood and/or polymer well treatments, is the synthetic partially hydrolyzed polyacrylamide (HPAM) and its derivatives. ... -
CO2 Foam Stabilization with Nanoparticles and EOR in Fractured Carbonate Systems
(Master thesis, 2015-06-18)This thesis is a part of an ongoing study of CO2 foam mobility control in the Reservoir Physics group at the Department of Physics and Technology (IFT) at the University of Bergen. The goal of this thesis was to evaluate ... -
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 ... -
