Sedimentary characteristics and oil-gas geological significance of northern slope in Lingshui Sag, Qiongdongnan Basin [PDF]

Youqicang pingjia yu kaifa
A gasfield with reserves exceeding 100 billion cubic meters has been discovered in the Central Canyon on the southern slope of the Lingshui Sag in Qiongdongnan Basin. However, the northern slope shows poor oil and gas enrichment, with gas detected but no

Three-Dimensional Numerical Modeling of Confined and Unconfined Turbidity Currents – Model Development and Validation [PDF]

Port Said Engineering Research Journal
Turbidity currents are sediment-laden gravity currents that transfer sediments to deep sea and lake floors through erosion and deposition. These deposits form subaqueous fans in deep marine environments and can reduce reservoir storage capacity ...

Lithofacies and depositional regimes of the Kolosh Formation Successions in the Tigran region, North-eastern Iraq

Tikrit Journal of Pure Science, 2023
The current study depends on lithofacies analysis of Kolosh Formation at Tigran region in north-eastern Iraq. Depending on the physical criteria as grain size, color, texture, and etc., the formation is divided to five lithofacies: pebbly sandstone ...

Carbonate submarine fan deposits of the Mississippian Lake Valley Formation, Sacramento Mountains, New Mexico

The Depositional Record, 2023
Deep‐water carbonate deposition is relatively poorly understood but an area of vigorous research in academia and industry, where these deposits are a significant component of many unconventional petroleum reservoirs.

Water on Mars: Do submarine cyclic steps exist on the red planet?

Progress in Earth and Planetary Science, 2018
Submarine cyclic steps have a significant impact on the evolution of the ocean floor on Earth. These upper-flow regime bedforms should be even more common in Martian reduced-gravity environments.

Unraveling the Origin of the Messinian? Evaporites in Zakynthos Island, Ionian Sea: Implications for the Sealing Capacity in the Mediterranean Sea

Journal of Marine Science and Engineering, 2023
The new approach on depositional conditions of the Messinian evaporites in Zakynthos Island indicates that the evaporites in the Kalamaki and Ag. Sostis areas were redeposited during the Early Pliocene. They accumulated either as turbiditic evaporites or

Evolution of Miocene Submarine Fan Systems in the Northern Lingshui Sag, Qiongdongnan Basin, South China Sea

Journal of Marine Science and Engineering
The Miocene Sanya, Meishan, and Huangliu formations in the Qiongdongnan Basin (QDNB) record a complete evolutionary history of submarine fan systems, yet a continuous Miocene-scale depositional framework has not been established for the Northern Lingshui
