The progress in ultrahigh-resolution mass spectrometry (UHRMS) and related technologies
has significantly promoted the development of petroleomics. The study of petroleomics has …

Oil migration may influence the reliability of molecular maturity parameters. Sample extracts
from a shaly sequence subjected to intrasource migration, were characterized using FT-ICR …

Carbazole compounds are widely used in determining the direction of petroleum migration,
but the effect of thermal maturity on carbazoles is still ambiguity. In this paper, using …

Heavy oil is one of the most significant unconventional petroleum resources and one of its
formation mechanisms is biodegradation. The characterization of the molecular …

The maturity of sedimentary organic matter is a key parameter for evaluating oil and gas
resources. Existing maturity indicators have different evaluation principles and application …

The quality of any reservoir is strongly controlled by diagenetic processes, especially of
those that are comprised of mixed siliciclastic-carbonate sequences. An Eocene mixed …

The molecular fractionation of organic compounds through adsorption in minerals has wide
implications, including tracing the origins of life, carbon sequestration, and climate change …

如何准确评价沉积有机质特征是油气资源勘探开发工作的关键问题之一, 勘探开发实践证实高—
过成熟有机质特征评价尤其困难. 为此, 以松辽盆地下白垩统沙河子组, 四川盆地下志留统龙马溪 …

Research has identified and increasingly explored the micro-migration phenomenon in
shaly strata, which is currently one of the key scientific issues affecting shale oil …

Hydrothermal fluid plays a crucial role in the generation and migration of hydrocarbons
within sedimentary basins. Herein, we employed bulk analysis and high-resolution mass …
