One of the methods to cope with the increase of emitted greenhouse gases has been to capture CO2 gas from a point source and storing it within the Earths subsurface; “Carbon Capture and Storage” (CCS). Since 1996, Statoil and its partners have injected CO2 into a saline aquifer called the Utsira formation located in the North Sea. About 0.9Mt of CO2 is injected into the formation yearly, with a ...

Batymetridata, høyoppløselige seismisk data samt en sedimentkjerne fra indre Balsfjorden, Troms, nord-Norge, har blitt analysert for å undersøke sedimentasjonsprosesser i løpet av Holocen, med spesiell fokus på undersjøiske rasavsetninger. Hovedvekt av denne oppgaven ligger på analyse av den 8,67 m lange sedimentkjernen JM11-001-PC. Dette inkluderte beskrivelse av sedimentoverflate og røntgen ...

Geophysical evidence of a prominent BSR at Vestnesa Ridge and north to the northern flank of the Storegga slide escarpment infer that gas hydrates are ubiquitous within these regions. A wide range of fluid flow structures have previously been discovered from these regions, as well as gas seepage activity from pockmarks on the eastern segment of Vestnesa Ridge. This paper focuses on high-resolution ...

Oil and gas development in the Arctic is becoming a major focus in the industry today. However, compared to other regions, there is less experience regarding drilling operations in the Arctic environment. This fact raises concerns about high-risk scenarios, which might take place because of the harsh environmental conditions and the effects they have on various phases of operations, equipment and ...

With the increasing need for monitoring ship traffic in both coastal and open oceans, ship detection is an important application of synthetic aperture radar (SAR). This thesis investigates image products suitable for ship detection for complex data acquired in Terrain Observation by Progressive Scans (TOPS) mode. The research was based on studying how contrast enhancement algorithms suitable for SLC ...

Degradation of pressurized topside static mud equipment is a very complex process. Inspection is a helpful tool to monitor degradation and helps reduce the number of critical failures. If it is left undetected and unchecked, it can lead to leakage resulting in accidents. To set up an effective inspection program, the concepts of Risk-Based Inspection (RBI) can be utilized. RBI helps to develop an ...

In recent years, the petroleum industry started to look for new, unconventional energy resources. Peon, a shallow gas discovery in the northern North Sea, are being assessed as a possible energy resource. However, there are challenges related to reservoir pressure, sealing mechanism, and fluid migration. In this regard, geophysical and well log analyses is figured out to get a better understanding ...

Several ship detection algorithms have been developed over the years, where some of the most commonly used are the constant false alarm rate (CFAR) algorithms. There are challenges to the existing algorithms, both when it comes to processing time and difficult scene situations, such as heterogeneous ocean clutter and multiple targets. Existing algorithms that are equipped to handle situations ...

High-resolution two-dimensional (2D) multichannel seismic data was acquired in 2014 from the Svyatogor Ridge, a sediment drift on the northwestern flank of the Knipovich spreading ridge. Seismic data is here processed, and together with multibeam bathymetry data and a correlation with Ocean Drilling Program (ODP) Hole 909, an interpretation of the structural and stratigraphic framework of the Svyatogor ...

The 3D seismic survey ST0827 in the outer Vøring Basin reveals a complex fluid flow system consisting of hydrothermal vents, polygonal faults and acoustic pipes. The polygonal faults are bound to the fine-grained Top Brygge Formation and ooze-dominated Kai Formation. The Kai Formation is overlain by the Naust Formation, in which glacigenic debris flow units are observed. As polygonal faults can be ...
