Investigation of Leakage Paths in Well Abandonment
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)A large number of wells will have to be abandoned at the NCS and around the world. NORSOK D-010 states that a well that is permanently abandoned shall be abandoned with an eternal perspective and with zero leakage [1]. ... -
Investigation of mechanical property of aplite-based geopolymer for plug and abandonment
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)Historically and up to date, ordinary Portland cement (OPC) or a slight variation is the most widely used material for permanent Plug & Abandonment operation. However, there are several challenges related to cement usage. ... -
Investigation of temperature- and pressure effects on drilling fluid properties and related downhole torque and drag calculations
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)Increasing temperature and pressure with depth, affects the properties of drilling fluid. The effect of temperature and pressure on the density and viscosity of drilling fluid is of great importance. This is because, among ... -
Investigation of the transport mechanism of the cutting transport in drilling horizontal wells using high speed camera and PIV for analysis
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)Dynamical feature of particle dunes is investigated in a horizontal drilling well. Apparently, it is quite challenging to transport the cuttings in horizontal section of the well because the cuttings tend to settle down ... -
Investigation of transient scenarios in underbalanced drilling
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)When drilling underbalanced wells, the standard way consists to drill with a very low mud weight in order to obtain a well pressure lower than pore pressure. The flow of the fluids from the reservoir up to the tubing is ... -
Investigations of a drilling operation by using a simplified gas-liquid mathematical model
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-05-22)There was a strong wish to investigate the physics of fluid flow involved in drilling operations where nitrogen injection is used to lower the hydrostatic pressure. This work is based on a reduced version of the full ... -
Kalavryta and Kerpini Fault Block: Investigation into correlation and nature of sub-horizontal layers; Corinth Graben, Greece.
(Master thesis, 2015-06)The Gulf of Corinth is located in West-Central Greece and is the result of a Pliocene-Recent, asymmetric extensional rift system. The region offers an excellent opportunity to study rotated fault blocks and the various ... -
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 ... -
