To assess how the grain size/rock fabric of laboratory-matured shale samples impact oil, gas production, and formation pores during laboratory thermal maturation, cores (4.5 mm*1 cm) bulk rock, millimetric equidimensional rock fragments (3*3 mm), fine grind powder (<200 μm) were obtained from an organic-rich mudstone (Kimmeridge Clay Fm. “KCF”, Yorkshire, UK) artificially matured under anhydrou...

The exploration well ANH-CR-Montecarlo-1X, in the southern part of Cesar-Ranchería basin Colombia, cuts sedimentary rocks assigned to Cogollo Group (Barremian-Cenomanian). present study integrates petrographic techniques (thin section microscopy and scanning electron microscopy), geochemistry (total organic carbon pyrolysis rock-eval) basic petrophysics establish thermal maturity potential thes...

The Taranaki Basin in New Zealand presents the most promising territory for strategies of hydrocarbon exploration and development. This basin contains multiple source rock levels its sedimentary successions formed during syn- post-rift periods. deepest rocks, found Rakopi Formation, were deposited deltaic to deep marine environments consist gas-prone coal organic-rich mudstone lithofacies. Howe...

Contrasting tillage strategies not only affect the stability and formation of soil aggregates but also modify concentration thermostability organic matter associated with aggregates. Understanding carbon retention ability under different systems is essential to ascertain potential terrestrial storage. We characterized (SOC) within various aggregate size classes both zero conventional using nove...

In this study, we propose a predictive model for maceral discrimination based on Raman spectroscopic analyses of dispersed organic matter. micro-spectroscopy was coupled with optical and Rock-Eval pyrolysis set seven samples collected from Mesozoic Cenozoic successions the Outer sector Carpathian fold thrust belt. Organic petrography evidence type II/III kerogen complex organofacies composed by...

Abstract The present study aims to investigate the origin, type, thermal maturity and hydrocarbon generation potential of organic matter paleo-depositional environment Early Paleocene (Danian) Hangu Formation outcropped in Kala-Chitta Range Northwest Pakistan, Eastern Tethys. Organic-rich shale coal intervals were utilized for geochemical analyses including TOC (total carbon) Rock–Eval pyrolysi...

The paper discusses the issues of interaction organic matter and siliceous-carbonate mineral matrix in unconventional reservoirs Upper Devonian Domanik Formation Kama Depression Volga-Ural Basin. is composed organic-rich low-permeability rocks. Lithological geochemical peculiarities rocks were studied using light microscopy, X-ray diffraction analysis (XRD), scanning electronic microscopy (SEM)...
