The formation time of the Chang 6 reservoir was determined semi-quantitatively by petrographic observation, fluorescence spectral analysis, homogeneous temperature test and salinity calculation of fluid inclusions in the Chang 6 reservoir of the Qilicun oilfield, as well as sonic time difference method to recover the stripping thickness of the strata at the end of the Early Cretaceous, based on the study method of burial-thermal evolution history map with homogeneous temperature cast points of i...

Weathering of biomarkers is a physical, geochemical and biological process
that alters the oil components. Whether in petroleum geochemistry or
environmental impact studies, knowledge of mechanisms, residence times and
chemical intermediates is essential to describe the scientific and technical
bases of oil deterioration. This report attempts to review the concepts of oil
weathering and its biomarkers specifically, in order to inform studies related
to the impact of spills in marine environments...
