In this study, we identified the luminescent layers containing a significant amount of alginite in Upper Jurassic–Lower Cretaceous Bazhenov Formation named “the alginite-rich layers”. Lithological and geochemical methods were used to determine distinctive features these evaluate their impact on total petroleum generation potential Formation. We have shown that composition differs significantly ...

Chemometric methods can enhance geochemical interpretations, especially when working with large datasets. With this aim, exploratory hierarchical cluster analysis (HCA) and principal component analysis (PCA) methods are used herein to study the bulk pyrolysis parameters of 534 samples from the Persian Gulf basin. These methods are powerful techniques for identifying the patterns of variations i...

Organic matter (OM) type critically controls the hydrocarbon generation potential and organic pore development in black shales. However, maceral variation lacustrine shales its control on are not yet well understood. In this study, 15 Chang 7 Member shale samples of Yanchang Formation, Ordos Basin, were investigated with petrography, Rock-Eval pyrolysis, a scanning electron microscope to study ...

The exploration of hydrocarbon resources plays a critical role in fulfilling the world’s increasing demand for energy. In this regard, distribution and source rock characteristics coal measure stratum whole basin are important must be studied. However, systematic research has not been conducted yet. study, organic geochemical data, drilling fieldwork were used to examine Upper Paleozoic stratum...

This study focuses on the thermal maturity of Permian deposits from Zagros Basin, Southwest Iran, employing both optical methods (Thermal Alteration Index, Palynomorph Darkness Vitrinite Reflectance, UV Fluorescence) and geochemical analyses organic matter (Rock Eval Pyrolysis MicroRaman spectroscopy) applied to Faraghan Formation along two investigated Darreh Yas Kuh e surface sections. Furthe...

A~tract--The Cretaceous/Tertiary (K/T) boundary is marked by extensive changes in the sedimentary fossil record of continental and marine life. Organic matter in sediments from above and below the K/T boundary has been studied to identify consequences of the biotic extinctions and of the changes in biological productivity which occurred at this time. Data from locations encompassing a variety o...

The purpose of the study in Karangkobar area was to investigate source rock potential fine-grained surface samples clastic sediments. use for Indonesia is still limited. We conducted geochemical laboratory analyses this research, including Total Organic Carbon (TOC), Rock-Eval Pyrolysis (REP), and Gas chromatography–mass spectrometry (GCMS). Seventeen have been analyzed their TOC content. resul...
