Seismic Sequence Stratigraphy Applied to Reservoir Recognition and Evolution on Marine Carbonatic Ramp—Macaé Group (Albian to Cenomanian) of Campos Basin

Geological Journal, EarlyView.
A classic oil producing interval of the Campos Basin—Macaé Group is revisited through seismic stratigraphic analysis, providing a stratigraphic framework, characteristic depositional and relative time positioning for several complex structural settings.

Formation conditions and the main controlling factors for the enrichment of shale gas of Shanxi Formation in the southeast of Ordos Basin, China

Journal of Natural Gas Geoscience, 2023
Based on the dissection of the geological characteristics of typical shale gas wells, the relationship between reservoir-forming factors and shale gas enrichment is deeply analyzed, and the controlling factors of shale gas enrichment are summarized.

Characteristics of Gravity Flow Deposits in the Benin Basin (Benin) and Implications for Oil and Gas Exploration

Geological Journal, EarlyView.
This study reveals that the underexplored Benin Basin features a narrow shelf and steep slope, which promoted the development of multi‐phase, stacked channel‐lobe complexes. These gravity flow deposits, further enhanced by bottom current reworking, reveal a significant undiscovered Upper Cretaceous stratigraphic play with considerable petroleum ...

Bryozoan‐Rich Carbonate Units of the Erfoud Area (SE Morocco) Record Latest Katian to Early Hirnantian Interglacial Intervals

Geological Journal, EarlyView.
In this study, we re‐examine the depositional architecture of the Erfoud limestone in Morocco. Introducing new biostratigraphic constraints from chitinozoan assemblages, we show that Katian to Hirnantian bryozoan‐pelmatozoan meadows reflect flooding events linked to a series of interglacial transgressions known to have occurred immediately prior to the

Micropore Characteristics and Gas-Bearing Characteristics of Marine-Continental Transitional Shale Reservoirs in the East Margin of Ordos Basin

Adsorption Science & Technology, 2021
In order to deeply study the exploration potential of Carboniferous-Permian marine-continental transitional shale reservoirs in the Ordos Basin, the shale samples from well Y1 in the central-southern part of the Hedong Coalfield were used as the research object.

Miocene to Quaternary Tectonostratigraphic Evolution of the Northern Section of the Burdur‐Fethiye Shear Zone, South‐Western Türkiye

Geological Journal, EarlyView.
New zircon ages reveal that lacustrine sedimentation initiated in the Late Miocene (Messinian), revising earlier Pliocene age assignments. The study results support the interpretation of the northern BFSZ as a broad left‐lateral transtensional shear zone rather than a discrete sinistral fault or simple extensional graben array.

A preliminary study on the geological conditions and indexes for the accumulation of shale gas in the marine-continental transitional facies sediments in the South North China Basin

Frontiers in Earth Science, 2022
At present, the Carboniferous-Permian shale gas in the South North China Basin is still in the exploration stage, and the understanding of the microscopic pore structures, mineral composition and hydrocarbon enrichment law of the marine-continental ...

Ichnology of the Rhätsandstein in the Exter Formation (Triassic), Germany

Geological Journal, EarlyView.
Trace fossils from the Rhätsandstein of southern Germany record repeated colonization of high‐energy shallow‐marine substrates before the Triassic–Jurassic transition. The assemblage reflects environmental and preservational controls on ichnodiversity.

Geological conditions and reservoir characteristics of various shales in major shale-hosted regions of China

China Geology
China is home to shales of three facies: Marine shale, continental shale, and marine-continental transitional shale. Different types of shale gas are associated with significantly different formation conditions and major controlling factors.
