The purpose of this study is to characterize the relationship between organic material and thermal maturity during the process of evaluation of hydrocarbon potential. Samples studied include Miocene high volatile bituminous coal and coaly shale collected from outcrops and exploration wells in Hsinchu-Miaoli area, NW Taiwan, density centrifuge separated macerals, bituminous coal and anthracite f...

The lacustrine shale in the second member of Kongdian Formation (Ek2) is most significant target oil exploration Cangdong Sag, Bohai Bay Basin, China. To investigate occurrence mechanisms and to reveal influencing factors mobility Ek2, a series analyses (X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), total organic carbon (TOC) analysis, Rock-Eval pyrolysis, low-t...

Sediments of Stefanets Mb. (Etropole Fm.), consisting mainly shale and siltstones, are investigated by Rock-Eval pyrolysis. The samples from the Middle Jurassic section (Bajocian in age), outcropping within western part Balkan orogenic system Bulgaria, were analyzed to study their hydrocarbon generative potential. obtained TOC contents range 0.69–1.97 wt.%. Inorganic carbon (TIC) total sulphur ...

Understanding the performance and role of each formation in a petroleum play is crucial for the efficient and precise exploration and exploitation of trapped hydrocarbons in a sedimentary basin. The Lorestan basin is one of the most important hydrocarbon basins of Iran, and it includes various oil-prone potential source rocks and reservoir rocks. Previous geochemical studies of the basin were n...
