Summary: Salt structures can provide valuable insights into tectonic and depositional processes due to their distinct responses. However, previous studies have not systematically identified, mapped, or classified the evolution of multi-stage salt structures in a regional context. The Southern North Sea, with its abundant 3D seismic data, offers a unique opportunity to investigate the evolution of salt structures. Our study used a comprehensive seismic dataset and analyzed the time-thickness variations around salt structures to examine their evolution across different sub-basins. We found that multi-stage salt diapirs in the Southern North Sea developed through three regional phases and up to five local stages.

Summary: The study utilized high-resolution seismic data to conduct a detailed analysis of Quaternary sediments in the northern North Sea, revealing that the sediment deposition in the North Sea trough-mouth fan may have occurred later than previously thought. Additionally, evidence of sediment disturbance by ice-stream activity near the base of the Norwegian Channel was observed. A new age model proposed for the Quaternary sediments in the northern North Sea provides insights into glacial events and aids in reconstructing spatial and temporal patterns of sediment subsidence and fluid overpressure in the North Sea Basin.

Summary: Salt interpretation using seismic data is crucial for structural interpretation and oil and gas exploration. The current interactive segmentation methods cannot be directly applied to 3D seismic data and require significant human intervention. Therefore, we propose a workflow that involves simulating salt data and training and testing on large amounts of 3D synthetic salt data. Our approach, which combines a 3D U-net model with graph-cut, achieves more efficient and accurate segmentation of 3D salt bodies compared to fully automatic methods.

Summary: This study investigates the palaeostress state around a rising salt diapir in the Dutch North Sea using 3D seismic volume and borehole data. The results reveal radial, polygonal, and keystone faults, and show that the stress conditions around the diapir vary in different zones. Stress inversions for 10,401 interpreted faults indicate sub-horizontal minimum and intermediate principal palaeostresses, with a close to vertical maximum principal palaeostress. The findings have implications for the analysis of salt diapirs in carbon sequestration, gas storage, and oil and gas production.

Summary: The application of high-resolution seismic geomorphology and lithological data offshore The Gambia documents a complex tectono-stratigraphic history through the Cretaceous, revealing the spatial-temporal evolution of submarine canyons and estimating the intra- versus extra-basinal sediment budget. The evolution of the continental margin from the Jurassic to Aptian is characterized by carbonate escarpment development followed by the first major siliciclastic sediment delivery during the Albian age, linked to hinterland exhumation events. Submarine canyonisation initiated at the palaeo-shelf edge, controlled by lithological contrast, and lasted for approximately 28 million years, dissecting the inherited seascape topography.

Summary: An extensive 3D seismic dataset was used to study the contemporary hydrocarbon distribution and historical fluid migration in Melville Bay offshore northwest Greenland, providing the first inventory of shallow gas and gas hydrate in this area. The study found that gas accumulation is influenced by underlying paleo-rift topography and multiple glacial events, which have led to gas concentration in Cenozoic stratigraphy above the ridge. Gas hydrate deposits mainly adjusted to glacial-interglacial changes by expansion and dissociation at the base, and are relatively inert to current global warming levels.

Summary: 3D seismic reflection data was used to map 784 enigmatic ridge-furrow structures in water depths of 0.8-1.7 km offshore Angola. These structures are characterized by asymmetric ridges and intervening furrows, with two possible origins considered: erosional scours or bottom-current generated sediment waves. The interpreted sediment waves are likely transported by a palaeo-bottom-current regime with specific flow characteristics towards the west-southwest/south-southwest direction.

Summary: The petroleum resource assessment obtained from laboratory tests on old core samples tends to underestimate the in situ resources. This study investigates the hydrocarbon loss and restoration by comparing preserved and exposed core samples. It is found that previous studies have severely underestimated the in situ hydrocarbon potential due to factors such as sample crushing and crucible waiting. A new restoration model is proposed to compensate for these losses.

Summary: Quartz cement is an important authigenic mineral in the tight sandstones of the Shaximiao Formation in the Sichuan Basin. This study analyzed the silicon sources of the quartz cement using mineralogical, fluid inclusion, and geochemical data. The results showed that smectite alteration and dissolution of aluminosilicate minerals were the primary sources of silicon for quartz cementation. Contributions from volcanic material hydrolysis and pressure solution were relatively minor. The presence of chlorite films inhibited the development of quartz overgrowths and had minimal impact on reservoir quality.
