Fluid Heterogeneity in Tight Unconventional Reservoirs
(Doctoral theses at NTNU;2020:270, Doctoral thesis, 2020)This thesis deals primarily with layer-wise fluid heterogeneity in tight unconventional reservoirs. The industry has almost exclusively assumed that the fluid system within a well-box, i.e. contributing production to a ... -
Forearc crustal structure and controlling factors on basin formation across the southernmost Northern Andes: Geophysical and Geological Investigations
(Doctoral theses at NTNU;2021:11, Doctoral thesis, 2021)The southernmost region of the Northern Andes was subject to the collision and accretion of the Caribbean Large Igneous Province (CLIP) during Late Cretaceous. A process that led to the entrapment of an oceanic crustal ... -
Framework Factors with Critical Influence on Safety, Health and Environment in the Mining Industry

Framework for automated well planning and Digital Well Management
(Doctoral theses at NTNU;2020:357, Doctoral thesis, 2020)This research was initiated to establish mitigations of the performance gap in well construction. Expert representatives from each discipline spend on average 4,000 to 6,000 manhours of planning for each offshore well, ... -
A framework for evaluating deep sea mining systems for seafloor ma ssive sul phides deposits
(Doctoral theses at NTNU;2020:280, Doctoral thesis, 2020)Loki’s Castle, a SMS site of interest located in the Norwegian jurisdiction, was used to illustrate the established framework. The established economic block model was used to support a sensitivity analysis which shows ... -
Frå Nidarosen til Nidarneset: Ein ingegrert naturvitskapleg – arkeologisk – historisk rekonstruksjon av framveksten av Trondheim
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:65, Doctoral thesis, 2006)The centre of Trondheim is located on a peninsula at the mouth of Nidelva in the county of Sør-Trøndelag, Norway. A limited part of the town is an automatically protected heritage site Mellomalderbyen Trondheim (the medieval ... -
Free convection flow and heat transfer in pipe exposed to cooling
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:189, Doctoral thesis, 2010)One of the challenges with thermal insulation design in subsea equipment is to minimize the heat loss through cold spots during production shut down. Cold spots are system components where insulation is difficult to ... -
Frequency dependent elastic properties of shales – Impact of partial saturation and stress changes
(Doctoral theses at NTNU;2017:151, Doctoral thesis, 2017)Shales are the most common constituent of the overburden of conventional hydrocarbon reservoirs. As such, they have a strong influence on seismic waves and knowledge about overburden mechanical properties is required for ... -
