Effectiveness of Post-injection Grouting in Controlling Leakage: A Case Study
(Journal article; Peer reviewed, 2011) -
The effects of anisotropy on AVO behavoir on shallow reflectors from Sleipner
(Master thesis, 2015)AVO analysis is an important tool in discriminating between oil, gas and brine saturated rocks in a given reservoir unit. Although, to use AVO analysis can be challenging as there are many pitfalls connected to different ... -
Effects of Confining Stress on the Post-Peak Behaviour and Fracture Angle of Fauske Marble and Iddefjord Granite
(Peer reviewed; Journal article, 2019)In general, the strength of rock and rock mass is non-linearly associated with the confining stress. Thus, the non-linear Hoek–Brown strength criterion (Hoek and Brown 1980, 1982) is more appropriate than the linear ... -
Effects of Fracture Capillary Pressure and non-straight Relative Permeability Lines
(Master thesis, 2012)This thesis will investigate the effect of fracture capillary pressure in the fractures, and the effect of non-straight fracture relative permeability lines. -
Effects of Harsh Weather on Delayed Wireline Formation Fluid Sampling
(Springer Series in Geomechanics and Geoengineering;, Chapter, 2019)This paper discusses two cases where formation fluids were sampled after prolonged exposure to drilling fluid invasion. The long exposure occurred due to suspension of rig activities following the arrival of the Typhoon ... -
Effects of Mechanical Stirring and Ultrasound Treatment on the Separation of Graphite Electrode Materials from Copper Foils of Spent LIBs: A Comparative Study
(Peer reviewed; Journal article, 2023)In this paper, mechanical stirring and ultrasonic treatment are used to separate graphite electrode materials from copper foils in recycling spent lithium-ion batteries (LIBs). Firstly, the effects of ultrasonic power ... -
Effects of Particle Shape on Mechanical Properties of Aggregates
(Master thesis, 2015)Aggregates are one of the primary building material used in the world. The durability of construction aggregates will therefore depend upon the quality of aggregate mechanical properties. It is therefore important to ... -
Effects of pre-salt structures onpost-salt structural development investigated by analogue sand box experiments
(Master thesis, 2011)The Angola margin displays a broad range of salt-related structures such as, normalfaults, rollovers, salt diapirs, folds and reverse faults, developed by gravity sliding which is the major mode of deformation of post-salt ... -
Effects of reservoir compaction on seismic and gravity monitoring
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:6, Doctoral thesis, 2011)The compacting reservoir embedded in a homogeneous, isotropic and elastic medium, known as Geertsma’s model, is a model commonly used in feasibility studies for forecasting time-lapse changes due to hydrocarbon production. ... -
Effects of surface roughness on the hydrophilic particles-air bubble attachment
(Peer reviewed; Journal article, 2022)Bubble-particle attachment is a key factor in various material processing such as wastewater treatment and flotation separation. Nanobubble's formation and its stability on hydrophobic surfaces with and without surfactants ... -
Effects of Well Temperature on Wellhead Fatigue Assessment
(Doctoral theses at NTNU;2018:175, Doctoral thesis, 2018)Summary Construction and later re-entering of subsea wells require the use of a tubular component called riser to connect the rig to the wellhead. The motions of the rig and of the riser itself, which are created by the ... -
Effekt av injeksjonsmateriale på skjærstyrken til diskontinuiteter
(Master thesis, 2020)Berginjeksjon er et viktig tiltak for å redusere vanninnstrømning i tunneler og andre bergrom. Det har derfor vært mye fokus på å forstå hvordan injeksjonsmateriale trenger seg inn i bergmasser og hvordan benytte injeksjon ... -
Effekten av Binære Interaksjonsparametere på Fase-oppførsel
(Master thesis, 2020)Nøyaktig modelering av fluider har vært en målsetting for reservoaringeniører siden 1940-tallet. Basert på forbedringer i datakraft siden 1970-tallet, har kubiske tilstandslikninger (EOS) blitt brukt for å beskrive ulike ... -
Effekten av kunstig infiltrasjon i basseng for økt uttak av grunnvann - En case på Doroøya i Orkland kommune
(Master thesis, 2023)Masteroppgaven er et bidrag til et forskningsprosjekt i regi av Norsk Vann som undersøker potensiale kunstig infiltrasjon har for små og mellomstore vannverk i Norge. Et vannverk på Doroøya i Orkland kommmune som benytter ... -
Effekten av Romeriksportens tunnellekkasjer under Østmarka - Tolkning av hydrologiske tidsserier fra langtidsovervåkning
(Master thesis, 2018)Grunnvann i fjellmassiver er en stadig utfordring ved konstruksjon av undergrunnsanlegg. Ved siden av at vanninnsig under driving reduserer fremdriften, kan innlekkasjene resultere i senket grunnvannsnivå i omkringliggende ... -
Effekten av streamer feathering på seismisk data
(Master thesis, 2019)Når en seismisk kabel blir eksponert for sterke havstrømmer i løpet av en 2D seismisk undersøkelse, blir den planlagte 2D undersøkelsen isteden til en 3D seismisk undersøkelse med begrenset dekning. Kablene drives sidelengs ... -
Effektiv prosjektering og 3D-modellering av samferdselstunneler
(Master thesis, 2015)Samferdselsutbygginger har store kostnadsoverskridelser. Bedre modeller å bygge etter vil gi mindre feil og mangler i prosjekteringen og føre til lavere kostnader for prosjektene. Kravene som samferdselsetatene stiller ... -
Efficient Drilling Problem Detection: Early fault detection by the combination of physical models and artificial intelligence
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:170, Doctoral thesis, 2009)The drilling of an oil or gas well is an expensive undertaking. Hence, it is not surprising that mistakes and accidents during drilling incur a high cost. Accidents could result in the loss of expensive equipment and ... -
