Solid bitumen is the intermediate products during the oil and gas generation, and widely
exists in petroliferous basins all over the world. Besides damaging the reservoir physical …

Asphaltene-trapped (adsorbed or occluded) biomarkers are considered a valid source of
information for crude oil with severe secondary alterations. However, thermal stress might …

Large amounts of natural gas have been discovered in the Sinian-Cambrian reservoirs of
the central Sichuan Basin, southwest China. However, the gas origin and accumulation …

Understanding the origin of natural gas in deep and ultra-deep reservoirs with multiple
potential source rocks remains challenging due to the complex thermal evolution of …

The thermal evolution of components trapped in matrix of asphaltenes is supposed to be
retarded, as compared to the free ones. Studying the geochemical evolution of trapped …

In this study, a series of 3D molecular models of solid bitumen from the Sichuan Basin were
established using solid-state 13 C nuclear magnetic resonance (NMR) spectroscopy and …

In this study, swelling experiments for three natural solid bitumen samples in two types of
organic solvents were conducted to explore the location of the swelling between the solid …
