Evaporative fractionation is a complex phenomenon associated with the separation of gas from oil in the subsurface, generally involving migration fractionation and gas invasion. The concentrations and distributions of diamondoid hydrocarbons in…
Thermal maturity level of crude oil samples is commonly investigated using popular biomarkers such as steranes and hopanes. Although crude oil's thermal maturity is an important goal for petroleum engineers and geochemists, fewer researches have been…
SINOPEC has made significant progress in natural gas exploration in terrigenous tight sandstone in the Western Sichuan Depression, making it one of the predominant exploration areas in the Sichuan Basin. Although the Chengdu large gas field was…
Position-specific isotope analysis (PSIA) of propane provides novel insights into formation mechanisms and thermal maturity of natural gas. The evolution of thermogenic propane in natural gas was simulated with pyrolysis experiments using types I,…
Fifty-five oils and condensates produced from unconventional reservoirs in lower Eagle Ford Shale were characterized. Most of the samples are from the play area east of the Maverick Basin and west of the San Marcos Arch, while five samples are from…
Pyrolysis experiments were conducted on lacustrine organic-rich shale from Cangdong Sag in Bohai Bay Basin, China, to investigate the impact of hydrocarbon generation on shale pore structure evolution. Thermal evolution is found to control the…
The level of crude oil thermal maturity has so far been done using biomarker ratios. Despite valuable geochemical information provided by biomarker ratios, they usually face problems in thermal maturity assessment. This paper aims to introduce new…
