Relationship between the origin of organic-rich shale and geological events of the Upper Ordovician-Lower Silurian in the Upper Yangtze area

Marine and Petroleum Geology, 2019
Based on detailed sedimentological observations and geochemical analyses, four geological events have been identified, and a genetic depositional model has been established within a sequence stratigraphic framework.

Experimental evaluation of oxidation sensitivity in organic-rich shale reservoir

, 2020
Organic-rich shale reservoirs are rich in reductive minerals, such as pyrite and other organic matters. The working fluid for the development of shale gas reservoirs contains large amount of dissolved oxygen.

Studies of the storage and transport of water and oil in organic-rich shale using vacuum imbibition method

, 2020
The inorganic pores, organic pores, and kerogen matrix are important media to store water and oil in shale rocks. We present a vacuum imbibition method to identify the volume of water and oil in these media.

Influence of Pore Water on the Gas Storage of Organic-Rich Shale

, 2020
Previous studies that utilize dry samples have been conducted on the nanoporosity of organic matter in shale. However, underground shales contain pore water that may greatly influence their pore structures and adsorbed gas content.

Geochemical characteristics of organic-rich shale, Upper Yangtze Basin: Implications for the Late Ordovician–Early Silurian orogeny in South China

Palaeogeography, Palaeoclimatology, Palaeoecology, 2020
The tectonic–sedimentary environment of the Upper Yangtze Basin in China underwent significant changes from the Late Ordovician to Early Silurian. The widely distributed shale formed during this interval has recorded key information about paleo-ocean ...

The Maturity of Organic-Rich Shales Using Microimpedance Analysis

SPE Annual Technical Conference and Exhibition, 2010
Abstract The increasing importance of organic-rich shales, ORS as hydrocarbon reservoir rocks has lead to a demand for better understanding of the processes that lead to shale maturity. An improved understanding of these processes in the laboratory can lead to development of methods for their indirect geophysical detection at in-situ ...

Fluid expulsion and microfracturing during the pyrolysis of an organic rich shale

Fuel, 2019
During progressive burial, low permeability organic-rich shale rocks evolve chemically and physically as the temperature and stress increase and organic matter matures. The transformation of organic matter into hydrocarbon, followed by its expulsion into

Petrographic and geochemical characteristics of organic-rich shale and tuff of the Upper Triassic Yanchang Formation, Ordos Basin, China: implications for lacustrine fertilization by volcanic ash

Canadian journal of earth sciences (Print), 2019
The Upper Triassic Chang 7 Member lacustrine organic-rich shale of the Yanchang Formation of the Ordos Basin is a significant hydrocarbon source rock containing abundant of tuff intervals ranging from millimeters to tens of centimeters thick. The present
