The marine shale of the Upper Ordovician Wufeng Formation–Lower Silurian Longmaxi Formation is main source rock and target gas exploration in southern Sichuan Basin. maturity organic matter (OM) a vital indicator for evaluation. Due to lack vitrinite, Wufeng–Longmaxi Formations Basin difficult accurately evaluate. In total, 33 core samples were selected observe optical characteristics solid bit...

Estimation and correct determination of vitrinite equivalent reflectance in rock is crucial for the assessment source both conventional unconventional hydrocarbon deposits. These parameters can be determined laboratories on samples. Laboratory measurements provide only point information. However, use well logs could overcome discontinuities data throughout a study interval. Attention has been p...

We determine the organic matter content, its thermal maturity, genetic type, and source rock potential of Miocene sedimentary rocks in Czech Carpathian Foredeep. In Republic Foredeep represents a peripheral foreland basin formed due to tectonic emplacement loading Alpine-Carpathian Thrust Wedge onto passive margin Bohemian Massif. Random vitrinite/huminite reflectance measurements maceral analy...
