Petrological characteristics and shale oil enrichment of lacustrine fine-grained sedimentary system: A case study of organic-rich shale in first member of Cretaceous Qingshankou Formation in Gulong Sag, Songliao Basin, NE China

Petroleum Exploration and Development, 2018
Taking organic-rich shale in the first member of Cretaceous Qingshankou Formation in the Gulong Sag, northern Songliao Basin as an example, this study examined the lithofacies classification, petrological characteristics, pore size distribution and their

Pore structure and fractal characteristics of transitional shales with different lithofacies from the eastern margin of the Ordos Basin

Energy Science & Engineering, 2023
To better characterize the heterogeneity of transitional shale pore structure and understand its impact on shale gas enrichment, fine characterization of the pore structure of different shale lithofacies was performed by field‐emission scanning electron ...

Paleo-sedimentary environment and lithofacies of Jurassic Da’anzhai Member in the Central Sichuan Basin-A case study of Well Ren’an 1

Frontiers in Earth Science, 2023
The Jurassic Da’anzhai Member in Sichuan Basin is an important target for shale oil exploration. Whole rock X-ray diffraction analysis, thin section, SEM and TOC testing, as well as major and trace element analysis are used to analyze the relationship of

Ultrasonic velocity anisotropy of Jurassic shales with different lithofacies

Journal of Geophysics and Engineering
AbstractGiven the growing importance of organic-rich shale as unconventional reservoirs, a thorough understanding of the elastic and anisotropic behavior of shales is of great concern. However, for lacustrine shales, the complex lithofacies assemblage with geological deposition makes it challenging. Four lithofacies (argillaceous, mixed, siliceous, and

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

Types of shale lithofacies assemblage and its significance for shale oil exploration: A case study of Shahejie Formation in Boxing Sag [PDF]

, 2023
In order to realize the efficient development of lacustrine organic-rich shale oil reservoir in the lower sub-member of the third member of the Eocene Shahejie Formation and the upper sub-member of the fourth member of the Eocene Shahejie Formation in ...

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.

Lithofacies types, reservoir characteristics and silica origin of marine shales: A case study of the Wufeng formation–Longmaxi Formation in the Luzhou area, southern Sichuan Basin

Natural Gas Industry B, 2022
Shale, which is a fine-grained sedimentary rock, differs in reservoir quality (RQ) and completion quality (CQ) as the result of variations in its mineral and organic-matter compositions. The RQ and CQ directly affect shale gas exploitation.
