Clean-up of horizontal well using ICD
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-13)An efficient clean-up process is a key factor determining horizontal wells productivity. Numerous factors cause formation damage around wellbore vicinity and numerous treatments have been developed to mitigate each damaging ... -
CO2 Methanation over Carbon Nanotubes Supported Nickel Catalyst
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)CO2 hydrogenation to methane has become one of the most researched area due to the possibility of reducing CO2 emissions and at the same time to be utilized in the power-to-gas or biogas upgrading technology. Catalyst is ... -
CO2 sequestration in gas-condensate reservoirs
(Master thesis, 2014-07-30)In this thesis, it is being analyzed effects of carbon dioxide (CO2) injected into a retrograde gas reservoir to enhance liquid production from such reservoirs while simultaneously sequestering amounts of CO2. Mixing ... -
CO2-foaming agent retention in fractured chalk models: Experiments and simulations
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)Injection of CO2-gas can improve the oil recovery. In naturally fractured reservoirs such as chalk, injection of CO2-gas can result in early gas breakthrough because the gas can use the fractures as pathways from the ... -
