Buckling of composite Cable: Simulation and physical testing of buckling of the composite cable inintervention operations within a production tubing
(Master thesis, 2011)Recent advances in drilling technology have enabled wells reaching up to 10 km and beyond. Conventional intervention technology has limitations when reaching into the high deviated and long horizontal sections of these ... -
Building a geological reservoir model in the North Sea
(Master thesis, 2014)This thesis is submitted as the partly requirement to fulfill the Masters of Science (M.Sc.) in Petroleum Geosciences at the Department of Petroleum Geosciences (IPT), Norwegian Universi-ty of Science and Technology ... -
Building, Testing and Qualifying New Hook Load Rig
(Master thesis, 2014)To meet the growing demand for energy, the petroleum industry is looking in places previously thought to be unreachable. The continued search is causing the oil and gas industry to drill more advanced wells than ever. With ... -
Bulk oil-water pipe separation: performance of MPPS prototype with spiked oil
(Master thesis, 2021)Vann produseres vanligvis sammen med hydrokarboner under utvinning av olje og gass. Når et felt modnes, forventes den produserte vannmengden å stige. Vannet må skilles fra olje og gassen og behandles før det slippes ut ... -
Bullheading- Praksis og modelering
(Master thesis, 2014)I denne oppgaven vil bullheading bli vurdert og modellert. Oppgaven vil vise utvalgte bruksområder for metoden og hvilke problemer og utfordringer som ligger i bruken av disse og sette fokus på momentene som genereres under ... -
Burial induced changes in physical sandstone properties: A case-study of North Sea and Norwegian Sea sandstone formations
(Journal article; Peer reviewed, 2017)The changes in physical properties of sandstones with burial depth are a result of mechanical and chemical compaction processes. These processes are affected by rock microstructure, pressure regimes and temperature history. ... -
Burst Dynamics, Upscaling and Dissipation of Slow Drainage in Porous Media
(Peer reviewed; Journal article, 2021)We present a theoretical and experimental investigation of drainage in porous media. The study is limited to stabilized fluid fronts at moderate injection rates, but it takes into account capillary, viscous, and gravitational ... -
Byåsentunnelen: Setningsproblematikk, tids- og kostnadsberegninger
(Master thesis, 2012)Bygging av tunnel fra Sluppen til Byåsen har igjen blitt aktuelt under utbedring av den siste delen av Stamvegringen rundt Trondheim. Tunnelen er planlagt med stigning opp til 7 % og rundkjøring i fjell. I tillegg vil ... -
Bæreevnen til utvidbare friksjonsbolter ved varierende installasjonstrykk, borehullruhet og borehulldiameter. Basert på uttrekkstester fra betongblokk og utviding av bolter i friluft
(Master thesis, 2022)18 uttrekkstester ble utført på utvidbare friksjonsbolter installert i en betongblokk. Boltene er av Swellex-typen som installeres med vanntrykk, og ikke behøver mørtel eller polyester. Ved uttrekkstestene ble deformasjonen ... -
Calculation and Visualization of Energy Dissipation and Energy Balance in Reservoir Models
(Master thesis, 2020)During the production lifetime of a hydrocarbon reservoir, various forms of energy are involved: external energy through wells, internal energy stored in the reservoir itself, and dissipated energy as heat released to the ... -
Calculation of acoustic wave velocities based on digital rock models
(Master thesis, 2021)Beregning av bølgehastigheter basert på μCT-bilder av bergarter kan gi verdifull kunnskap som kan brukes ved tolkning av seismisk data. For å sammenligne hastighetsresultatene fra en avlastet kjerneprøve med petrofysiske ... -
Caledonian structural, metamorphic and magmatic evolution of the Rödingsfjället Nappe Complex
(Master thesis, 2022)Rödingsfjälldekkekomplekset og Helgelanddekkekomplekset utgjør de to store komponentene i øverste allokton og består av bergarter med både oseanisk og kontinental affinitet som representerer den ytterste marginen av ... -
Can Heating Induce Borehole Closure?
(Peer reviewed; Journal article, 2020)The current study shows that heating a cased borehole in low-permeability shale rock can induce plastic deformation, leading to the closure of the casing annulus and decreasing annulus connectivity. The thermally induced ... -
Can heating-induced creep result in shale barriers for P&A applications?
(Chapter, 2017)It has been shown that some shale formations form barriers around a casing of a well due to shale creep that results in closure and sealing of the annulus around the casing. The existence of such shale barriers facilitates ... -
Capacity Enhancement in Rock and Tunnel Engineering in Nepal
(Journal article, 2022)In the recent past, infrastructure development activities have gained momentum in Nepal. Many roads are being and will be upgraded to enhance transport efficiency. The hydropower development activities are in full momentum. ... -
The capacity of creeping shale to form an annular barrier
(Master thesis, 2017)This report was written in Pau, France, as part of an internship in Total E&P Drilling & Wells Division, Geomechanics Entity, under supervision of Kun Su. Shale displacing inwards in the wellbore is a well-recognized ... -
Capillary washboarding during slow drainage of a frictional fluid
(Peer reviewed; Journal article, 2023)Numerous natural and industrial processes involve the mixed displacement of liquids, gases and granular materials through confining structures. However, understanding such three-phase flows remains a formidable challenge, ... -
