Sedimentological Influence on Physical Properties of a Tight Sandstone Reservoir: The Cretaceous Nenjiang Formation, Southern Songliao Basin, Northeast China

Frontiers in Earth Science, 2021
:The Nenjiang Formation, south of Songliao Basin, has many hydrocarbon bearing units, but currently the understanding of the distribution of viable reservoir sandstones is too limited to support a development strategy.

Alluvial ridge morphology on avulsing rivers

Sedimentology, EarlyView.
ABSTRACT Alluvial ridges are built by preferential channel‐belt deposition and control river avulsions, yet a systematic analysis of their morphology has been missing. To address this gap, we analyse a globally distributed dataset of 8970 alluvial ridge flanks on 14 different rivers.

Geomorphic characteristics of dryland distributive systems

Revista de Geomorfologie, 2021
Dryland distributive systems include different types of depositional bodies: distributary systems, alluvial fans, fan deltas, lacustrine deltas and sea deltas.

Outcrop and subsurface characterisation of a mixed tidal and wave‐influenced coastline (Triassic Red Beds, SE Spain)

Sedimentology, EarlyView.
ABSTRACT Paralic depositional systems are complex and heterogeneous sedimentary environments, presenting challenges for predicting reservoir architecture and connectivity. Their stratigraphic and facies variability arises from the dynamic interplay between fluvial, tidal and wave processes, and their sensitivity to sea‐level fluctuations, sediment ...

Airborne radar imaging of subaqueous channel evolution in Wax Lake Delta, Louisiana, USA

Geophysical Research Letters, 2016
Shallow coastal regions are among the fastest evolving landscapes but are notoriously difficult to measure with high spatiotemporal resolution. Using Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) data, we demonstrate that high signal‐to ...

Prototype geological model of distributary channel based on the high density well pattern

IOP Conference Series: Earth and Environmental Science, 2019
Abstract The western part of the central zone lies in the middle of the Saertu anticline structure. It can be divided into 77 sedimentary units, with the permeability ranging from less than 10 mD to more than 1000 mD. Diversity of plane sand body morphology, phase change frequently.

Multi‐proxy sequence stratigraphy of a mixed carbonate–siliciclastic shelf across the Jurassic–Cretaceous transition

The Depositional Record, Volume 12, Issue 4, September 2026.
An integrated facies, MS and XRF‐based approach applied to the Tithonian–Berriasian Sidi Khalif Formation (central Tunisia) resolves five Tithonian and eight Berriasian third‐order sequences, showing how mixed carbonate–siliciclastic shelves record coupled eustatic, climatic and tectonic controls and providing a transferable template for similar mud ...

Study on sedimentary architecture of single sand body in shallow water deltas based on dense well pattern and interwell tracer data： A case study of Es21 and Es22 in Shenger District of Shengtuo Oilfield， Dongying Sag

Youqi dizhi yu caishoulu
Sand bodies in distributary channels and mouth bars of shallow water deltas are often distributed in continuous sheets， making it difficult to accurately classify the single sand body， limiting the accurate prediction of remaining oil distribution and ...

Impacts of Sedimentation and Diagenesis on Deeply Buried Reservoir Quality of a Rift Basin: A Case Study of Wenchang Formation in the Lufeng Depression, Pearl River Mouth Basin, China

Geofluids, 2022
The deeply buried reservoirs of Wenchang Formation in the Lufeng Depression, Pearl River Mouth Basin, display strong heterogeneity, and the major controls for the development of high-quality reservoirs remain unclear.

River Sand and Gravel Mining: Global Drivers, Impacts, and Pathways for Sustainable Management

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract River sand and gravel are mined worldwide at volumes that now rival their natural replenishment, yet quantitative knowledge of this mining activity and its consequences lags far behind many other global environmental pressures. We synthesize 411 peer‐reviewed studies published since 1974 within a new Driver‐to‐Management Pathway for ...
