Basin Analysis of the Pegasus Basin, New Zealand - A Frontier Basin Uniquely Bounded by Two Opposing Subduction Systems
Sæterdal, Hanne S (Master thesis, 2017)Pegasus Basin is bounded in northwest by the active convergent Australian margin, and in the south by the bathymetric ridge of Chatham Rise, which represents the Mesozoic convergent plate boundary along the Gondwana ... -
Deep-seated faults and hydrocarbon leakage in the Snøhvit Gas Field, Hammerfest Basin, Southwestern Barents Sea
Mohamed, Yasin; Lippard, Stephen John; Omosanya, Kamaldeen Olakunle; Johansen, Ståle Emil; Harishidayat, Dicky (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 ... -
Electromagnetic Modelling and Inversion of Seafloor Massive Sulphide Deposits - Imaging of SMS Deposits and the Asthenosphere at the Atlantic Mid-Ocean Ridge
Tegnander, Jonas Fagerli (Master thesis, 2017)Seafloor massive sulphides (SMS) are seen as an increasingly important mineral resource for the future. Fewer mineral discoveries are being made in the shallow subsurface onshore, and therefore a more petroleum related ... -
Estimating Net Erosion in the Western Barents Sea
Elks, Richard Anthony (Master thesis, 2016)Quantification of uplift and erosion in the western Barents Sea has been a relevant and challenging problem for geoscientists for several decades. Uplift and erosion processes have implications for petroleum prospectivity, ... -
Evolution and Character of Supra-Salt Faults in the Easternmost Hammerfest Basin, SW Barents Sea
Omosanya, Kamaldeen Olakumle; Johansen, Ståle Emil; Hidayat, Dicky Haris (Peer reviewed; Journal article, 2015)Research analyzed the influence of parameters derived from urban planning, architecture, building materials and technology, building physics, users and patterns of use, the measured thermal performance of the envelope and ... -
Evolution of Tromsø Basin in the light of salt tectonics
Aghataghiyev, Elnur (Master thesis, 2015)Two dimensional (2D) seismic data was used for seismic interpretation of the main horizons in Tromsø Basin and mapping of the salt structures in the study area. Seismic data covers area of approximately 134x140 km comprising ... -
Fault-sill interaction: Implications for magma routing and overburden faulting in the Vøring Basin, Norwegian North Sea.
