An experimental study of low salinity EOR effects on a core from the Yme field
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)The best known proposed mechanisms for low salinity effect are fines migration, pH increase, double layer expansion and multicomponent ionic exchange (MIE). Even though many mechanisms have been proposed, none of them have ... -
An introduction to engineering challenges in Extended Reach Drilling (ERD) wells and a simulation study of the effect of varying hole size in a well section
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-15)This thesis investigated Extended Reach Drilling (ERD), an embedded technology for drilling high-inclination, long horizontal directional wells. The objective was to introduce important engineering challenges in ERD wells ... -
An optimization study of current drill bit technology for the Troll Field, Norway
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)In the current study geology, drill bit technology and drilling challenges at the Troll Field are mapped. It has been established that the Troll Reservoir Formation consists of unconsolidated shallow marine sandstone ... -
Analysis of 3D post-stack data from offshore east Scotland
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012-06-29)This study concentrates on reprocessing a cube of post-stack 3D seismic data from offshore East Scotland to improve resolution of the data. The main application of the reprocessing is to allow for a better interpretation ... -
Analysis of drill-string based on case study of ultra-deep drilling on Kola Peninsula.
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06)The topic of the following project is devoted to the theme of drilling of the ultra-deep wells and in particular to the optimization of the length of dual aluminum-steel drill string as a one of the concept which have been ... -
Analysis of drilled wells on the Norwegian Continental Shelf (NCS)
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-17)Safe drilling operations are a result of integrated geo-mechanical engineering and drillstring mechanical engineering. Torque and drag modeling is used by the oil and gas industry in all phases of drilling a well: Planning, ... -
Analysis of Factors Contributing to Long Term Shallow Gas Migration to Seabed in Surface Casing Annulus
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-07)A common observation is a low rate gas bubbling from the outside of the 20” surface casing on wells located in the Haltenbanken area on Norwegian Continental Shore. This phenomenon is known as long term shallow gas migration ... -
