TLDR
Pore-evolution models from immature organic-matter (OM) -rich Barnett and Woodford mudstones were compared with models previously developed from low-maturity OM-lean Boquillas (Eagle Ford-equivalent) mudstones to investigate whether different mineralogy (siliceous vs. calcareous) exerts different catalytic and sorption effects and influences OM-pore origin and evolution as discussed by the authors.About:

A review of shale pore structure evolution characteristics with increasing thermal maturities
TL;DR: Gao et al. as mentioned in this paper presented the state-of-the-art of shale pore structure evolution studies with increasing thermal maturities and found that both the inorganic and organic diagenesis control the shale protein structure evolution process.

TL;DR: In this paper, small angle neutron scattering (SANS) analysis was performed on six Bakken Shale samples with different maturities to reveal the complexities in the pore structure, and the results showed that the Bakken samples have a very small porosity value (less than 1%) and a very large specific surface area (larger than 180995 cm−1) in the measuring pore size range (pore diameter: 1-200 nm).

Mechanism of shale gas occurrence: Insights from comparative study on pore structures of marine and lacustrine shales
TL;DR: In this article, the pore structures of marine and lacustrine shales were characterized and the effects of organic matter abundance, maturity and inorganic minerals on porosity were investigated.
Journal ArticleDOI
On the petrographic distinction of bituminite from solid bitumen in immature to early mature source rocks
TL;DR: In this article, the distinction of solid bitumen from bituminite and alginite in immature to early mature source rocks is discussed, using typical organic petrography images, including samples from hydrous pyrolysis experiments.
Journal ArticleDOI
Formation and occurrence of organic matter-hosted porosity in shales
TL;DR: In this article, the authors show that the vast majority of SEM-visible organic matter-hosted pores develop within solid bitumen and not in structured organic matter (kerogen), and reaffirm that shale mineral content is a key factor in preservation or destruction of organic-matter-hosting porosity.

Petroleum Formation and Occurrence
TL;DR: The early transformation of organic matter from organisms to geochemical fossils and Kerogen has been studied in the literature as mentioned in this paper, with a focus on the migration and accumulation of oil and gas.
Journal ArticleDOI
Unconventional shale-gas systems: The Mississippian Barnett Shale of north-central Texas as one model for thermogenic shale-gas assessment
TL;DR: In this article, the authors estimate that the Barnett Shale has a total generation potential of about 609 bbl of oil equivalent/ac-ft or the equivalent of 3657 mcf/acft (84.0 m 3 /m 3 ).
Journal ArticleDOI
Morphology, Genesis, and Distribution of Nanometer-Scale Pores in Siliceous Mudstones of the Mississippian Barnett Shale
TL;DR: In this article, the authors used scanning electron microscopy to characterize the pore system in the Barnett Shale of the Fort Worth Basin, Texas, showing that the pores in these rocks are dominantly nanometer in scale (nanopores).
Journal ArticleDOI
Spectrum of pore types and networks in mudrocks and a descriptive classification for matrix-related mudrock pores
TL;DR: In this paper, a pore classification consisting of three major matrix-related pore types is presented that can be used to quantify matrix related pore and relate them to pore networks.

Sedimentary Organic Matter: Organic facies and palynofacies
TL;DR: The importance of sedimentary organic matter is highlighted in this article, where the authors discuss the nature of organic matter in sediments and the importance of the palynofacies analysis in sequence stratigraphic context.
