Study of Cuttings Transport Using Water-Based and Oil-Based Drilling Fluids
(Doctoral theses at NTNU;2018:108, Doctoral thesis, 2018)Cuttings transport is a topic of great interest in the oil and gas drilling industry. Insufficient cuttings transport leads to several expensive problems. Knowledge and selection of the drilling fluids is one of the important ... -
Study of development alternatives for remote offshore, low energy reservoirs: the Wisting field case
(Master thesis, 2017)This work summarizes a series of analysis conducted to determine an optimized field development plan for Wisting oil field. The field presents several unique challenges, such as low reservoir pressure, very shallow reservoir ... -
Study of Fluid Velocity in Eccentric Annulus
(Master thesis, 2011)To provide zonal isolation and avoid leakages behind the casing it is important to obtain a high quality cementing job. High quality cement is a result of a good drilling fluid displacement. In order to be able to control ... -
Study of Inflow Control Device Completion in Gullfaks field
(Master thesis, 2010)This report is written with focus on advanced completion with Inflow Control Valves in Gullfaksfield. ICD is meant to have two effects; first is to even out the pressure difference between heel and toe of the well, which ... -
Study of non-local equilibrium options in reservoir simulators
(Master thesis, 2013)AbstractThe recent IT improvements in areas such as CPU speed, memory, parallel computing and programming languages have allowed more complex physical models to be created for reservoir simulators. One of the issues that ... -
Study of Pattern Search Optimization and Implementation of Hooke-Jeeves Direct Search for Production Optimization using Perforations
(Master thesis, 2016)This thesis concerns the topic of petroleum production optimization using perforations. A plug-in by PhD student Einar Baumann was extended to include a second pattern search method: Hooke-Jeeves direct search. Originally ... -
A study of the Lower Cretaceous Åsgard Formation in the South Viking Graben, North Sea
(Master thesis, 2017)The Åsgard Formation of Lower Cretaceous age in the South Viking Graben represents a formation of great interest in petroleum exploration in the North Sea, but is poorly understood. The area of study is in the North Sea; ... -
STUDY ON MATERIAL PROPERTIES AND TESTING OF VARIOUS ROCK TYPES, DEVELOPMENT OF INVESTIGATION PROCEDURE AND TEST METHODOLOGY FOR FUTURE PROJECTS
(Master thesis, 2017)This master thesis aims to provide insight and qualitative information about swelling mechanisms in volcanic rocks, in particular the swelling of rocks related to hydropower water tunnels. Additionally, traditional laboratory ... -

(Master thesis, 2019)Den norske vannkraftindutrien er et resultat av over hundre år med erfaring fra utvikling av design og bygging av vannkraftprosjekter. Erfaringene har resultert i en norsk spesialitet, ufôrete trykktunneler og -sjakter. ... -
Study on the swelling potential of some selected rocks
(Chapter, 2014)For clay minerals the swelling mechanisms and factors influencing on the swelling potential is widely explained and confirmed through comprehensive research. When it comes to intact rocks there are questions regarding both ... -
Study on the Swelling Potential of some Selected Rocks
(Master thesis, 2014)Weaknesses zones consisting of sheared and fractured rock mass have a swelling potential in the presence of clays rich in montmorillonite. When it comes to intact rocks there are questions regarding both the swelling ... -
Sub-basalt imaging: a new approach to model and understand the Faroe Islands basalt
(Master thesis, 2011)The main part of the work carried out in this thesis has been concentrated around the building of in-homogeneous velocity and density models, representing basalt. The models have a strong link to the real geology since ... -
Subaqueous rock-avalanche deposits exposed by post-glacial isostatic rebound, Innfjorddalen, Western Norway
(Journal article; Peer reviewed, 2016)This paper presents a detailed description of deposits and landforms of multiple rock avalanches in Western Norway, one of which fell onto water-saturated sediments in Innfjorddalen below the former water level. Deposits ... -
Subsalt imaging: Sensitivity to the velocity model
(Master thesis, 2011)Subsalt exploration is an area of increasing interest, but imaging under salt structures is still very challenging and an increased understanding of subsalt imaging is needed. The focus of this master’s thesis is on the ... -
