In situ evidence of earthquakes near the crust mantle boundary initiated by mantle co2 fluxing and reaction-driven strain softening
(Journal article; Peer reviewed, 2019)This study aims to understand the process behind the worldwide connection between deep crustal/upper mantle earthquakes and CO2 emissions along faults in rift zones. We do this by studying CO2-induced mineral reactions ... -
In-depth assessment on the structural geological and engineering geological condition of the weakness zone at Svandalsflona HPP
(Master thesis, 2019)Stutakvelven er en sjakt med 45 graders helning som fungerer både som innløpstunnel og svingesjakt. Den er en del av Svandalsflona vannkraftverk som er lokalisert i et område preget av deformerte kaledonske skyvedekker. ... -
In-Depth Understanding of ICD Completion Technology Working Principle
(Journal article, 2022)The rate-controlled production (RCP) inflow control devices (ICDs) are valves placed in the lower completion of oil and gas wells, capable of autonomously controlling the reservoir inflow. This completion technology ... -
Inclination Control and Deviation Detection (Create Matlab agents to report wellbore Inclination and Deviation)
(Master thesis, 2019)Inclination or deviation related well problems are well known problems during drilling operation. These problems are like tool failure, stuck pipe, logging problem, casing running challenge and borehole cleaning problem. ... -
Inclusion of advection in fractures in the line source equation for analysis of thermal response tests
(Peer reviewed; Journal article, 2024)Proper design of larger ground source heat pump installations, and borehole thermal energy storages (BTES) requires determination of on-site thermal properties of the ground by performing a thermal response test (TRT). The ... -
Index Tests and Their Applications - Determining Rock Strength and Strength-anisotropy as a Function of Inclination by use of Index Testing and Mathematical Modelling
(Master thesis, 2015)Drilling problems in shale continue to be an expensive problem in the petroleum industry due to lack of information concerning rock mechanical parameters. Conventional laboratory tests are expensive and time consuming, as ... -
Inducing Latereal Drillstring Movements to Improve Hole Cleaning
(Master thesis, 2020)Borestrengsrotasjon er en velkjent måte å forbedre hullrensing i høyavviksbrønner. I denne oppgaven undersøkes hullrensingseffekten av heisesysteminduserte laterale borestrengbevegelser både for seg selv, og i kombinasjon ... -
Influence of annular mud and barite content on ultrasonic detection of shale barriers
(Master thesis, 2020)I denne avhandlingen undersøkes forholdene rundt baritt og dets bruk i boreslam. Ultrasoniske metoder for logging bak brønnrør beskrives, med fokus på å skille mellom barittholdig boreslam, lav-impedans sement og skifer. ... -
Influence of Casing Shoe Depth on Sustained Casing Pressure
(Master thesis, 2012)In 2006 the Petroleum Safety Authority Norway (PSA) performed a well integrity survey. The survey indicated that about 20 % of wells on the Norwegian Continental shelf (NCS) may suffer from well integrity issues. Most of ... -
Influence of Drilling Parameters on Cuttings Transport
(Master thesis, 2019)Transport av borekaks er et viktig tema i boreindustrien, som med rett utførelse kan spare industrien masse penger. Kunnskap om hvordan hver enkelt boreparameter påvirker hullrensing er essensielt for å unngå nedetid på ... -
The Influence of Elastic Anisotropy on Borehole Stability
(Master thesis, 2016)This thesis investigates the effect of elastic anisotropy on borehole stability, with the purpose of determining how significant this effect is. How this anisotropy affects borehole stresses and borehole failure through ... -
Influence of Groundwater on Measurements of Thermal Properties in Fractured Aquifers
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:113, Doctoral thesis, 2012)Shallow boreholes equipped with borehole heat exchangers (BHE) connected to ground-coupled heat pumps are used for the heating and cooling of buildings. Accurate estimates of ground properties are essential to properly ... -
Influence of Hole Trajectory and Direction on MWD Survey Errors
(Master thesis, 2018)Wellbore positioning is important to meet directional drilling objectives. Inaccurate wellbore surveys can lead to wellbore collision, failure to penetrate thin reservoir sections and drilling of relief wells etc. Such ... -
Influence of ice to the stability of engineering rock slopes and ice securing measures in Cold Regions
(Master thesis, 2018)In cold regions, freezing is an important factor for weathering processes in rock slopes. The presence of ice in discontinuities can contribute to maintain the stability of rock slopes. But degrading permafrost and thawing ... -
Influence of jaw crusher parameters on the quality of primary crushed aggregates
(Journal article; Peer reviewed, 2020)A parameter study using a jaw crusher is designed to investigate the influence of feed gradation, feed rate, crusher setting and crusher speed on the crusher operation and the quality of the produced aggregates. The study ... -
Influence of lattice-preferred orientation with respect to magnetizing field on intensity of remanent magnetization in polycrystalline hemo-ilmenite
(Journal article; Peer reviewed, 2012)New experimental and computational approaches to interpret orientation and intensity of natural remanent magnetization (NRM) carried by lamellar magnetism are applied to historic magnetic measurements on a collection of ... -
