Deep Sea Mining: Towards Conceptual Design for Underwater Transportation
(Chapter, 2020)This paper presents the first steps towards conceptual design for the underwater transportation of minerals from seabed to shore for deep sea mining (DSM). The methodology is based on conceptual design using a systematic ... -
Deep structure and sub-basalt exploration of the mid-Norwegian margin with emphasis on the Møre margin
(Doctoral Theses at NTNU, 1503-8181; 2010:154, Doctoral thesis, 2010)This thesis addresses the use of potential field data in two main topics: sub-basalt exploration and structure of the deeper crust. Synthetic models and forward models of the Møre margin were constructed to test the ... -
Deep water Riserless Drilling
(Master thesis, 2011)This master thesis presents different techniques for riserless drilling in deep waters. The objective has been to see advantages and challenges as well as limitations concerning the different solutions presented and identify ... -
Deep-Sea Mining–A Bibliometric Analysis of Research Focus, Publishing Structures, International and Inter-Institutional Cooperation
(Journal article; Peer reviewed, 2022)Deep-sea mining is a multidimensional concept that requires interdisciplinary research and development to close the current knowledge gaps. This study conducts a bibliometric analysis of the research focus, publishing ... -
Deep-seated faults and hydrocarbon leakage in the Snøhvit Gas Field, Hammerfest Basin, Southwestern Barents Sea
(Peer reviewed; Journal article, 2016)High-quality 3D seismic data are used to analyze the history of fault growth and hydrocarbon leakage in the Snøhvit Field, Southwestern Barents Sea. The aim of this work is to evaluate tectonic fracturing as a mechanism ... -
Deep-seated faults and hydrocarbon leakage in the Snøhvit Gas Field, Hammerfest Basin, southwestern Barents Sea
(Master thesis, 2015)Abstract High-quality 3D seismic data are used to analyze the history of fault growth and hydrocarbon leakage in the Snøhvit Field, southwestern Barents Sea. The aim of this work is to evaluate role of tectonic fracturing ... -
Deepwater Drilling: Return Flow Through Hose
(Master thesis, 2010)As the petroleum industry enhances their efforts to locate and produce fields in more and more challenged areas, bigger and deeper boreholes are required. The hydraulics of the borehole suddenly becomes the major power ... -
Deformation mechanisms of blueschist facies continental metasediments may offer insights into deep episodic tremor and slow slip events
(Peer reviewed; Journal article, 2022)Exhumed fossil subduction zones are archives of the deformation conditions and mechanisms from depths not directly accessible. Microstructural analysis of samples exhumed therefrom offers insights into the micromechanics ... -
Deformation, Phyllonitization and Associated Element Mobilization of Granitoid Rocks: - A geochemical study of the Fagervika granitoid, Norway.
(Master thesis, 2015)The Fagervika granitoid is a felsic, peraluminous intrusion that was emplaced in oceanic crust at 481 Ma, now represented as the Bymarka ophiolite in Trondheim, Norway. It belongs to the Støren Group in the Upper Allochthon ... -
Deghosting of Marine Seismic Data Using Dual Sensor Technology
(Master thesis, 2013)An inevitable phenomenon called the ghost reflection has always been a problem in marine seismic acquisition. The great contrast in acoustic properties over the air-water interface is causing an almost perfect reflection ... -
Deliverability of Wells in Shallow Confined Aquifers of Non-Integer Spatial Dimensions
(Journal article; Peer reviewed, 2015)We propose a generalized methodology to predict the deliverability of wells in fractional drainage areas. A fractional model is characterized by a single term power-law variation of the rock properties. Such a model may ... -
DENUDATIONAL PROCESSESAND RELIEF DEVELOPMENTIN MOUNTAIN VALLEYS INWESTERN NORWAY:: A HOLOCENE TO CONTEMPORARY TIME PERSPECTIVE
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:290, Doctoral thesis, 2013)The evolution of mountain landscapes is controlled by the interactions between tectonic, climate and geomorphic surface processes through time. The rates at which mountain landscapes change today are a response of both, ... -
