Comparison of Organic-Rich Shales of Pennsylvanian Age in Indiana with New Albany Shale [PDF]
AAPG Bulletin, 1983 ABSTRACT Abundant black organic-rich shales occur in rocks of Pennsylvanian age in southwestern Indiana. They have not been well characterized except for a few thin intervals in small areas, the best example being at the abandoned Mecca Quarry in west-central Indiana.

Predicting the characteristic parameters of shale sweet-spot with complex resistivity
Terrestrial, Atmospheric and Oceanic Sciences, 2020 It is important to predict the capacity related parameters of reservoir such as brittleness, total organic carbon (TOC), in-situ stress, maturity of organic carbon (Ro), and buried depth in shale gas exploration and exploitation.

Molecular Simulation of CH4 Nanoscale Behavior and Enhanced Gas Recovery in Organic-Rich Shale
, 2022 Occurrence and transport are two important nanoscale behaviors in the exploitation of shale gas. Nanopores in a realistic shale organic matrix are composed of kerogen molecules, which will have a great impact on surface-gas interactions and gas ...

Depositional conditions of siliceous microfossil-rich shale during the Ordovician–Silurian transition of south China:Implication for organic matter enrichment [PDF]
, 2023 Knowledge of the paleoenvironment is crucial to understand organic matter enrichment and shale gas development. Like organic matter, siliceous microfossils such as radiolarians and sponge spicules are widely distributed in Late Ordovician to early ...

The influence of CO2 and CH4 mixture on water wettability in organic rich shale nanopore
Journal of Natural Gas Science and Engineering, 2020 CO2 has been considered as an effective fluid to replace CH4 in shale rock. Wetting behavior of water in CO2 / CH4 mixtures in organic nanopores is a key parameter influencing CO2 based enhanced gas recovery processes in shale.

Oil retention and porosity evolution in organic-rich shales [PDF]
AAPG Bulletin, 2017 ABSTRACT Petroleum is retained in shales either in a sorbed state or in a free form within pores and fractures. In shales with oil resource potential, organic matter properties (i.e., richness, quality, and thermal maturity) control oil retention in general. In gas shales, organic pores govern gas occurrence.
