Sedimentary facies and depositional processes of the Diexi Ancient Dammed Lake, Upper Minjiang River, China

, 2020
Landslide events causing rivers to become dammed are common natural disasters in mountainous area. Based on the sedimentary facies analysis of 44 sections between proximal and distal parts of a dammed lake, this study reveals the sedimentary facies ...

Fusing multiple frequency-decomposed seismic attributes with machine learning for thickness prediction and sedimentary facies interpretation in fluvial reservoirs

Journal of Petroleum Science and Engineering, 2019
Defining the boundaries, thicknesses and sedimentary facies of fluvial reservoirs (sand bodies) is critical for predicting hydrocarbon volumes, designing schemes for petroleum exploration and development and improving oil recovery.

Sedimentary facies and diagenesis of the Lower Miocene Rudeis Formation (southwestern offshore margin of the Gulf of Suez, Egypt) and implications for its reservoir quality

Marine Geology, 2019
Studying sedimentary facies and diagenetic peculiarities are highly important for the understanding of carbonate-reservoir quality, including those of relatively poorly-known areas of great economic importance. The Early Miocene Rudeis Formation (~60–191

Combining Image Editing and SinGAN for Conditional Sedimentary Facies Modeling

IEEE Geoscience and Remote Sensing Letters
Traditional sedimentary facies modeling using generative adversarial networks (GANs) usually requires extensive datasets for network training. However, obtaining large datasets that align with reservoir depositional characteristics is often complex and ...

Seismic stratigraphy and sedimentary facies analysis of the pre- and syn- Messinain salinity crisis sequences, onshore Nile Delta, Egypt: Implications for reservoir quality prediction

Marine and Petroleum Geology, 2019
This study provides the first high-resolution outlines of the Messinian sequence in the Nile Delta based on an integrated sedimentological, petrophysical and seismic stratigraphic approach.

Neritic Sedimentary Facies

2010
Understanding this vast depositional realm has been a protracted study. As each new sector of the continental margin was documented, the new findings necessitated re-evaluation of previous interpretations. This chapter is the result of a total re-study of all bottom samples acquired since 1989 and their placement in a facies scheme that is applicable ...

Sedimentary facies of iron formation

Economic Geology, 1954
Discussion of conclusions relative to the intensity and duration of chemical weathering during the Precambrian contained in a paper on the origin of the iron formations of the Lake Superior district; points out that lateritic iron ores locally more than 100 meters thick are being formed at present by chemical weathering processes in the Conakry ...
