S-wave kinematics in acoustic transversely isotropic media with a vertical symmetry axis
(Journal article; Peer reviewed, 2018)Acoustic transversely isotropic models are widely used in seismic exploration for P‐wave processing and analysis. In isotropic acoustic media only P‐wave can propagate, while in an acoustic transversely isotropic medium ... -
Samanhengen mellom skogsvegar, skogsdrift og skredfare - Ei studie av forhold i forbindelse med skogsvegutforming og flatehogst i hellande terreng som gir fare for jord- og flomskred ved Horg, Melhus kommune og Høvringslia, Sel kommune
(Master thesis, 2016)Det er ein tendens til at omfang av vassrelaterte skred er aukande i Noreg. Dette skyldast endringar i klima med meir nedbør og auka frekvens av ekstreme nedbørshendingar. Auka i omfanget av vassrelaterte skred kan også ... -
Same-Well Enhanced Oil Recovery (SWEOR) - Cyclic Hydrocarbon Production/Hydrocarbon Gas Injection in a Hydraulic Multi-Fractured Horizontal Well
(Master thesis, 2017)Unconventional reservoirs have gained big attention in the oil industry as these reservoirs constitutes huge amounts of hydrocarbon reserves. The required advanced production techniques as well as costs related to ... -
Same-Well Enhanced Oil Recovery in Tight Unconventionals
(Doctoral theses at NTNU;2023:67, Doctoral thesis, 2023)This thesis presents a numerical modeling study of two gas-based, same-well, enhanced oil recovery (SWEOR) processes—huff-and-puff (HnP) and fracture-to-fracture (F2F)—applied to tight unconventionals. The processes consist ... -

(Master thesis, 2014)- Teoretisk literaturstudie av bergmassekarrakter, grunnvannstrømning og for-injeksjonsteknikk- Presenter ulike metoder som kan benyttes for å oppnå en vanntett tunnel, med eksempler fra reelle prosjekter- Presenter ... -
Sammenligning av flybåren og bakkebaserte resistivitetsmålinger for å indikere kvikkleire i Orkdal, Trøndelag
(Master thesis, 2023)Denne masteroppgaven er skrevet som en del av et samarbeidsprosjekt mellom Norges geologiske undersøkelse (NGU) og Norges vassdrags- og energidirektorat (NVE), som ble initiert av Orkland kommune, Trøndelag i forbindelse ... -
Sammenligning av tre metoder for dimensjonering av oljevernberedskap
(Master thesis, 2011)Connie Synnøve Sperstad, Sammenligning av tre metoder for dimensjonering av oljevernberedskap, diplomoppgave i emne TGB4940, Institutt for geologi og bergteknikk, 102 sider. Arbeidet er utført i samarbeid med Det norske ... -
SAND & FINES IN MULTIPHASE OIL AND GAS PRODUCTION
(Master thesis, 2013)This thesis work focuses on multiphase flow in the oil and gas industry. As differences in temperatures and pressures come to play from the reservoir to the surface, in tubing and in pipelines, gas tend to dissolve and ... -
Sand Control solution for Ormen Lange ERD-Wells
(Master thesis, 2010)An Extended Reach Drilling (ERD) well is planned for the Ormen Lange field in order to tap isolated reserves and maintain production. However Low fracture gradient, poorly consolidated formation and high fines content all ... -
Sand injectites in the Northern North Sea: Mapping and understanding sand injectites on the Fram Field
(Master thesis, 2011)Sand injectites are found in several stratigraphic positions in the Cenozoic succession, over large parts of the North Sea. Sand injection occurs when the fluid pressure in a source sand exceed the lithostatic pressure, ... -
Sand injektitter i Oseberg området, nordlige Nordsjøen
(Master thesis, 2011)The main objective of this master's thesis has been to interpret sand injectites in the Cenozoic succession in the Oseberg area, northern North Sea. A sand injectite is mobilized sand that has intruded into a host lithology. ... -
Sand production modeling based on Acoustic Emission
(Master thesis, 2022)I denne artikkelen skal leseren finne en detaljert beskrivelse av en forskning dedikert til overvåking av sandproduksjon basert på akustiske utslippsmålinger. Løssandproduksjon er et alvorlig problem som vi kan finne i de ... -
Sand volumetric prediction study using SINTEF’s SandPredictor tool
(Master thesis, 2011)In this project a study of sand production using the Sand Predictor tool developed by SINTEF is presented. The program requires input data such as: logs of the field, which were collected; production data, which was processed ... -
Sandstone Provenance of the De Geerdalen Formation, Svalbard - Emphasis on Petrography and Chromium Spinel Compositions
