The determination of the abundances CHx, C = O and aromatic groups in chondritic Insoluble Organic Matter (IOM) coals by Infrared (IR) spectroscopy is a challenging issue due to insufficient knowledge on absorption cross-sections their sensitivity molecular environment. Here, we report calibration approach based 13C synthetic model material whose composition was unambiguously determined Direct-...

Coal, which is usually land plant in origin, occurs in many oil-producing basins. Microscopically, coal consists of various macerals (liptinite, vitrinite, and inertinite). The generative potential of coal reflects the hydrocarbon potential of the composing macerals (Kelly et al., 1985). Although most coals consist of predominantly vitrinite, some contain significant amounts (>20% of total mace...

Possessed of easy access to development and fair economic benefits, medium-high maturity continental shale oil gas have become the focus study in future. Shale mainly occur pores, but studies on pore characteristics occurrence are by no means sufficient. Focused from Middle Jurassic Lianggaoshan Formation Well TYX, Fuling block, southeast Sichuan Basin where a breakthrough exploration was recen...

The organic-rich shale of the Upper Cretaceous Qingshankou Formation is an important hydrocarbon source rock in Northeast China. In this study, taking lacustrine as example, geochemical analysis, including total organic carbon (TOC), Rock-Eval pyrolysis, maceral compositions, X-ray diffraction (XRD), and biomarker analyses, were carried out on twenty-four samples to evaluate geochemistry enviro...

As sediment accumulation indicates basin subsidence, erosion often is understood as tectonic uplift, but the amplitude and timing may be difficult to determine because sedimentary record missing. Quantification of therefore requires indirect evidence, for example thermal indicators such temperature, vitrinite reflectance fission tracks in apatite. However, always, types quality data choice mode...

Abstract The aim of this study is to provide a better understanding the type source input, quality, quantity, condition depositional environment and thermal maturity organic matter from Bukit Song, Sarawak, which has not been extensively studied for hydrocarbon generation potential. Petrological geochemical analyses were performed on 13 outcrop samples location. Two samples, having III mixed ke...

In this study, gold tube thermal simulation experiments were carried out on the soluble components (extracts) and insoluble (extracted coal-measure mudstones) of mudstones, diamondoid compounds in pyrolysis products quantitatively analyzed. The results showed that extracts extracted mudstones had undergone process formation decomposition during evolution. Based quantitative composition calculat...
