Dual gradient drilling - simulations during connection operations
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-15)As oilfields are ageing and depleting, operators are forced to start searching for oil in more hostile environments. These new environments can introduce new drilling challenges. Prospects like ultra deep water reservoirs ... -
Dual gradient drilling and use of the AUSMV scheme for investigating the dynamics of the system
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)Offshore drilling is one of the most challenging operations in the oil industry, due to the complexity of the operation and the harsh work conditions. Some marine prospects are difficult to drill with the present ... -
Dynamic Simulation Study on Alternative Marine Drilling Riser Materials in the Deep-Waters of the Norwegian Sea
(Master thesis, 2017-06-15)In the pursuit of more oil and gas to meet the growing demand and replace the declining production, the offshore industry is pushed to invest, explore and drill new wells in deeper waters with harsh environments and with ... -
Dynamics of multiphase dispersed systems in rotating annulus
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)An investigation of multiphase dispersed system dynamics in rotating annulus is described. The investigation was based on measuring rheological constant (viscosity) of two-phase flowing system. The flow was obtained between ... -
Effect of barium and strontium on low salinity waterflooding
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-27)Much work has been done on the subject of low salinity waterflooding (LSWF) as a potential enhanced oil recovery method. It has been shown many times that reducing the salinity of the injected brine could have a positive ... -
Effect of Colloidal Transport on CO2 Injectivity
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-15)Climate change is a long term change in weather due to Earth process, volcanic activity and change concentration of greenhouse gases such as carbon dioxide (CO2) in the atmosphere. CO2 is generated mainly from industrial ... -
Effect of core cleaning solvents on wettability restoration and oil recovery by spontaneous imbibition in surface reactive, low permeable limestone reservoir cores
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)The success of oil recovery, by water flooding, in naturally fractured, low permeable limestone reservoirs strictly depends on imbibition of injected water into the reservoir matrix block. Prerequisite of imbibition process ... -
