Given that kerogen is a source of vast amount hydrocarbons and organically–bound inorganic elements, it’s important to understand the thermal decomposition kinetics kerogen. Green River Shale contains significant immature (Type I), which can be an ideal for sample experimental study. In this study, Thermogravimetric Analysis Derivative Thermogravimetry (TGA/DTG) was used quantify weight loss du...

High hydrogen pressure pyrolysis (hydropyrolysis) was performed on samples of solvent extracted Kimmeridge Clay Formation source rock with a maturity equivalent to ca. 0.35% vitrinite re ̄ectance. We describe the types and distributions of organic nitrogen compounds in the pyrolysis products (hydropyrolysates) using GCMS. Compounds identi®ed included alkyl-substituted indoles, carbazoles, benzoc...

the kazhdumi formation of the bangestan group is a well-known and important source rock in most oil-fields in the zagros basin. in order to examine productivity of this formation in southwestern iran, and to correlate petrographical and palynological data with geochemical properties, one of the best outcrops of this formation, located in tange-maghar 45 km northwest of behbahan city, was sample...

The largest recorded carbon isotopic excursion in Earth history is observed globally in carbonate rocks of middle Ediacaran age. Known from the Sultanate of Oman as the 'Shuram excursion', this event records a dramatic, systematic shift in δ(13) Ccarbonate values to ca. -12‰. Attempts to explain the nature, magnitude and origin of this excursion include (i) a primary signal resulting from the p...

To study the influence of different organic-inorganic composition on adsorption in shale, taking Niutitang Formation shale Huijunba syncline southern Hanzhong as research object, based acid treatment to extract kerogen and wet chemicals. Extracting mineral components by oxidation method, a series isothermal experiments were carried out original rock, kerogen, samples. Through three-dimensional ...

Organic geochemical evaluation of the Madbi Formation as the main source rock of the Al-Jawf Basin, NE Central Yemen was the main objective of this study. The organic geochemical methods used in the study include: rock-eval pyrolysis, total organic carbon, and optical measurements as the vitrinite reflectance and thermal alteration index. In this study, 67 well core and side-well core samples o...
