On Processing and Inversion of Marine Magnetotelluric Data
(Doctoral theses at NTNU;2017:311, Doctoral thesis, 2017) -
Physics of Strain Burst in Hard Rock – Fracture characteristics and influences of the stiffness of the host rock mass
(Doctoral theses at NTNU;2022:242, Doctoral thesis, 2022)Rock burst is a phenomenon in which rock disintegrates, accompanied by the ejection of debris. Strain burst is a type of rock burst. It is directly associated with stress concentration after rock excavation. Overstressed ... -
Prediction and early detection of karsts for safer drilling in carbonates
(Doctoral theses at NTNU;2022:108, Doctoral thesis, 2022)Underestimation of drilling hazards in carbonates can lead to serious consequences to personnel and the environment. The history of drilling in carbonates has shown that the vast majority of drilling incidents are associated ... -
Processing of S-Wave Data in Orthorhombic Media
(Doctoral theses at NTNU;2020:296, Doctoral thesis, 2020) -
Quantitative Seismic Monitoring
(Doctoral theses at NTNU;2022:127, Doctoral thesis, 2022)Seismic data is the main input for reservoir characterization in developing plays, when - in general - only conceptual geological models and few wells are available. When repeated over time, in a process called 4D seismic ... -
Rock physics assessment of overburden stratigraphic sequences in the offshore Rovuma Basin, East African margin
(Doctoral theses at NTNU;2021:258, Doctoral thesis, 2021)The overall goal of this PhD research is to investigate production planning and control challenges in the semi-process industry and to develop an approach for addressing these challenges based on lean production and Industry ... -
Rock Stress Estimation for Unlined Pressure Tunnel Design
(Doctoral theses at NTNU;2021:345, Doctoral thesis, 2021)In underground hydropower projects rock tunnels are used extensively to convey water for the purpose of generating power. As these tunnels represent a major cost element in typical hydropower developments, efforts are made ... -
Seismic interpretation of the Levant Basin with emphasis on the Messinian Salinity Crisis
(Doctoral theses at NTNU;2019:269, Doctoral thesis, 2019)Brief summary: Sequences of evaporites kilometers-thick were deposited during the Messinian Salinity Crisis (5.97-5.33 Ma) in the various sub-basins of the Mediterranean Sea, forming a salt giant of more than 1 million ... -
Single-mineral provenance method development with a case study from the Late Triassic Barents Shelf
(Doctoral theses at NTNU;2021:300, Doctoral thesis, 2021) -
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 ... -
Subsurface structure and hydrothermal fluid circulation at the Mohns mid-ocean ridge: a multi-geophysical investigation
(Doctoral theses at NTNU;2020:283, Doctoral thesis, 2020)Despite the small size of submarine hydrothermal vents exposed on seafloor, the extent and geological significance of hydrothermal systems span over distance of kilometers both laterally and in depth. However, due to ... -
Surfactant Enhanced Oil Recovery in Fractured Reservoirs: Simulation study of surfactant spontaneous and dynamic imbibition
(Doctoral theses at NTNU;2019:387, Doctoral thesis, 2019)Water flooding has poor performance in fractured reservoirs with mixed- or oil-wet wettability. Surfactant could be used to improve oil recovery by changing wettability to more water-wet or reducing water/oil interfacial ... -
Well-Log Database and Automation of Well Log Depth Matching by Using Analytical Methods and Deep Learning
(Doctoral theses at NTNU;2022:104, Doctoral thesis, 2022)Well log data formats remain rigid, outdated, and difficult to understand and to work with. The amount of available documentation is limited, thus much of the valuable information held in these data formats is left behind ...
