Facies models of the Achimov Formation of East-Urengoiskoe license as the basis for optimizing exploration and field development patterns

Georesursy, 2020
The results of sedimentological core analysis of the Achimov Formation (Upper Valanginian, Lower Cretaceous) confirm that it was formed by higher efficiency systems of submarine fans in (relatively) deep marine basin.

Grain-Size and Discharge Controls on Submarine-Fan Depositional Patterns From Forward Stratigraphic Models

Frontiers in Earth Science, 2019
Submarine fans are important components of continental margins; they contain a stratigraphic record of environmental changes and host large accumulations of oil and gas.

Evolution of submarine canyons and hanging-wall fans: insights from geomorphic experiments and morphodynamic models [PDF]

Earth Surface Dynamics
Tectonics play a significant role in shaping the morphology of submarine canyons, which form essential links in source-to-sink (S2S) systems. It is difficult, however, to investigate the resulting morphodynamics over the long term.

Entangled external and internal controls on submarine fan evolution: an experimental perspective

The Depositional Record, 2020
Submarine fans are formed by sediment‐laden flows shed from continental margins into ocean basins. Their morphology represents the interplay of external controls such as tectonics, climate and sea level with internal processes including channel migration

Proximal to distal grain‐size distribution of basin‐floor lobes: A study from the Battfjellet Formation, Central Tertiary Basin, Svalbard

The Depositional Record, 2022
The grain‐size distribution of sediment particles is an important aspect of the architecture of submarine fans and lobes. It governs depositional sand quality and reflects distribution of particulate organic carbon and pollutants.

Quantification of Basin-Floor Fan Pinchouts: Examples From the Karoo Basin, South Africa

Frontiers in Earth Science, 2019
The topography of the seabed (orientation and gradient) and rheology of the flows greatly influences the character of basin-floor turbidity current deposits.

Spatial differentiation of submarine fans and distribution patterns of high-quality reservoirs in Miocene Meishan Formation, block 13-2, Lingshui Sag, Qiongdongnan Basin

Shiyou shiyan dizhi
Since the discovery of high-yield gas flows from the Miocene Meishan Formation in well LS13-C of block 13-2 in the Lingshui Sag, Qiongdongnan Basin, subsequent exploration drilling has failed to achieve commercial breakthroughs.

3D palaeogeographic reconstructions of the Phanerozoic versus sea-level and Sr-ratio variations: Discussion

Journal of Palaeogeography, 2015
Veacute;rard et al. (2015, Journal of Palaeogeography, 4(1): 64-84) claim that their global geodynamic model allows one to reconstruct the surface features of topography on land and in adjacent oceans (i.e., paleobathymetry) anywhere on the globe and at ...

Submarine landslides in the continental margins of the Arctic Basin

Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2018
A review of investigations devoted to submarine landslides of Norwegian-Barents Sea-Spitsbergen and Canadian-Alaskan continental margins is presented. The review includes general characteristics of the landslides and environments in which they are widely
