Key criteria for successful LNG market development to replace LPG in the Scandinavian market.
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06)The main goal of the thesis is to perform the comparative study of LNG and LPG markets and to examine key factors for successful LNG implementation on the Scandinavian market on competition with LPG. It was found that the ... -
Laboratory evaluation of sodium silicate for zonal isolation
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)A common problem for maturing oil fields is excessive water production. Ultimate oil recovery could be increased considerably by implementing an appropriate water production management. Solutions for managing excess water ... -
Late life field material balance analysis – Statfjord Fm.
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2012)Recently, it has become apparent that the prediction of the Statfjord reservoir potential determined from the ECLIPSE simulator differs from the actual formation performance, i.e. simulated fluid production results are too ... -
Late Paleozoic development of the Finnmark Platform, southwestern Barents Sea, Norway
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-12)Following the recent Gohta and Alta discoveries in the Loppa High by Lundin Norway AS in 2013 and 2014 respectively, there has been an enhanced interest for the Upper Paleozoic succession in the Norwegian Arctic Shelf ... -
Life Cycle of deepwater oil and gas operational challenges/solutions and simulation studies
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-08-21)Deepwater is defined as water depths that are greater than 1 000 ft. The exploration and development activities in deepwater are the Oil and Gas industry’s biggest challenges, and they demand a huge investment. However, ... -
Life Cycle Well Integrity and Reliability
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-11)This thesis presents a method for reliability based casing design. The method is inspired by the model described by Das et al. (2015) - A model for Well Reliability Analysis throughout the Life of a Well Using Barrier ... -
Log typing and electro-facies interpretation in Ekofisk field
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)Recognition of the dense zones in Ekofisk field is clearly observed from well logging through a specific peak in the neutron-density log. These zones appear to be intercalated in porous clean chalks in the middle part of ... -
Lost circulation experimental study in oil based mud and analyzing experimental data
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)The problem of lost circulation have for a long time occurred during the drilling operation. During the drilling through induced and natural fractures, huge drilling fluid losses lead to the higher operational expenses. ... -
Low salinity effect after sea water flooding in sandstone reservoirs
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)Clays are the main wetting minerals and have permanently negative surface charges. The negative charges must be balanced by; active cat ions, polar components or H+. pH changes is observed in the effluent by flooding in ... -
Low salinity water flooding as EOR method in chalk reservoir
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-11-11)During the last few years studies of the low salinity water flooding effect, in general, have demonstrated an additional oil recovery associated with flooding oil reservoirs with low salinity water. Numerous theories ... -
Low-frequency reflection seismic and direct hydrocarbon indication
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06)Low-frequency reflection seismic has been used as an indicator to detect hydrocarbons in petroliferous reservoirs. A number of spectral decomposition methods have been developed to derive seismic from time to frequency ... -
Low-frequency seismic analysis and direct hydrocarbon indicators
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)Low-frequency seismic analysis has been used as a possible direct indicator of the presence of hydrocarbons in reservoirs. Laboratory examples, synthetic studies and field examples in oil and gas exploration suggest ... -
LWSF simulation at larger scale
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)Low salinity water flooding is a field of science that is new and need more research to find a definite theory of what happens. There have not been done many modeling studies on this field. The objective of my thesis ... -
Main pump start-up pressure limitation control system when using thixotropic drilling fluids
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-07-01)Everyday drilling operations in the Norwegian Continental Shelf become more challenged. They include drilling of highly inclined long wells in depleted reservoirs within narrow geo-pressure margins. In addition, drilling ... -

Making a simple steady state model more appropriate for underbalanced drilling
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)In an underbalanced operation the well needs to be kept in underbalanced conditions at all time. That is, from the beginning to the end of the drilling process. This is necessary to keep well from formation damage and ... -
Managed pressure drilling from floaters
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-05)Drilling in challenging environments with different drilling hazards cause a lot of non-productive time (NPT), ie time where the rig is not drilling. Much of the challenging environments are in water depth demanding the ... -
