A study of several proposed alluvial fan deposits in the Kerpini Fault Block, Greece
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-19)The rift in the Gulf of Corinth is one of the most active rifts in the world. Regional N-S extension has caused normal faulting from the Gulf of Corinth and southwards into the Peloponnese Peninsula. The normal faulting ... -
A study of the diffusion coefficient term in counter current imbibition and its effect on production
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-14)It is believed that most reservoirs have at least some degree of fractures and spontaneous imbibition is considered to be one of the most important recovery processes in fractured reservoirs. The imbibiton process can be ... -
A study of two-phase drift-flux modeling in wells and corresponding slip relations
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)It was desired to investigate the two-phase drift-fl ux model's behavior in both steady-state and transient settings and shed some light on required slip relations. A numerical MATLAB model of the one-dimensional two-phase ... -
A temperature model for Extended Reach Drilling applications
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)Ensuring precise estimation of temperature is a critical process for well planning and real-time drilling operations, especially for Extended Reach Drilling (ERD). Therefore, a temperature model has been developed to predict ... -
A Theoretical Study of the Effect of Salt Precipitation on CO2 Injectivity
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06)Global concern on climate change due to the greenhouse effect has led to various efforts to tackle anthropogenic Green House Gas (GHG) emissions. Of the various GHGs, CO2 poses the greatest threat to the fight against ... -
Adaptive Observer Design for Linear Hyperbolic System in Managed Pressure Drilling
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)Managed Pressure Drilling (MPD) is a drilling technology that has been developed to manage and control the downhole pressure in the well in order to minimize drilling-related problems. This technology uses a pressurized ... -
Adsorption of quinoline onto illite at high temperature in relation to low salinity water flooding in sandstone reservoirs
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)Laboratory tests, as well as field tests, have shown that low salinity water flooding in sandstone reservoirs can improve the water wetness of the rock and thereby increase the oil recovery. Many mechanisms have been ... -
Advancement of P&A operations by utilizing new PWT concept from Archer
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-17)Many of the oil and gas fields on the Norwegian continental shelf (NCS) are approaching the end of field life. The Petroleum safety authority of Norway is putting pressure on the Exploration and Production (E&P) companies ... -
Alternative cement program for the surface casing in the skarv field
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)A phenomenon called Shallow Water Flow (SWF) was encountered when drilling the top sections at the Skarv field, causing difficulties when cementing the surface casing. This thesis describes a proposed cement program with ... -
