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 ... -
Subsea Chemical Storage and Injection Station - Single line batch re-supply of chemicals - An experimental investigation into displacement mechanisms and separation methods
(Master thesis, 2018)This thesis seeks to simplify the re-supply process of a subsea chemical storage and injection (SCS\&I) station by identifying possible alternative transport solutions. Specifically, this thesis explores the technical ... -
Subsea Chemical Storage and Injection Station - Single Line Batch Re-Supply of Chemicals - Operation Strategies and System Design
(Master thesis, 2018)The offshore industry is facing many challenges when it comes to maintaining operational efficiency. One of the biggest problems is related to flow assurance problems. To avoid such issues, different chemicals are transported ... -
Subsea CO2 Injection with Direct Offshore Offloading of CO2 – Modelling and Simulation Case Studies
(Master thesis, 2023)Abstract In the coming decades, burning fossil fuels will still be necessary, therefore Carbon Capturing and Storage (CCS) can aid in reducing greenhouse gas emissions. There are multiple technologies that can capture CO2 ... -
Subsea Drilling and Well Construction Cost Model
(Master thesis, 2020)Avgjørelser tas gjennom hele livssyklusen til et felt, der den største muligheten til å påvirke kostnadene er i de tidligste fasene. Det er derfor viktig å ta nøyaktige beslutninger i planleggingsfasene av feltutvikling. ... -
Subsea Field Layout Optimization
(Doctoral theses at NTNU;2022:33, Doctoral thesis, 2022)This study focuses on building a systematic method for the subsea field layout optimization with the aim of minimizing the overall field development cost. The subsea field layout optimization is a very complex problem which ... -
Subsea field layout optimization (Part I) – directional well trajectory planning based on 3D Dubins Curve
(Peer reviewed; Journal article, 2022)Directional well trajectory planning, which includes the optimization of the drilling site location and the trajectory between the drilling site to the completion interval, plays an important role in reducing subsea field ... -
Subsea field layout optimization (part II)–the location-allocation problem of manifolds
(Peer reviewed; Journal article, 2022)The location-allocation problem of manifolds, which is a part of subsea field layout optimization, directly affects the flowline cost. This problem has always been studied as a mixed-integer nonlinear programming (MINLP) ... -
Subsea field layout optimization (part III) --- the location-allocation problem of drilling sites
(Peer reviewed; Journal article, 2022)This study proposes an efficient method to optimize the subsea field layout with the aim of minimizing the subsea field development cost, based on the two methods introduced in Part I and Part II for solving the well ... -
Subsea road tunnels in the Faroe Islands
(Journal article; Peer reviewed, 2018)The Faroe Islands north of Scotland has a disproportionally large number of road tunnels. In addition to 44 km of existing tunnels, two further undersea tunnels totalling 22 km will be completed by 2023. A further 30 km ... -
Subsea templates for operation with subsea drones
(Master thesis, 2021)The next generation of subsea inspection, maintenance and repair (IMR) vehicles are drones capable of operating both autonomously and under human control. Many different technologies are required for the drones to as an ... -
Subsea Well Intervention in the North Sea - Learning from Mistakes and Experience
(Master thesis, 2012)BP Norway is well versed in well intervention from fixed platforms. The present Skarv field development will however require future subsea well interventions to take place from different floating vessels. BP has extensive ... -
