Oiliness gradation of hybrid sedimentary shale with low-moderate organic matter content: a case study of the Paleocene Shahejie Formation in Dongpu Depression, Bohai Bay Basin

Abstract Shale oil resources are abundant on Earth, of which hybrid sedimentary shale (HSS) oil is an important component, including high and medium–low organic matter content (TOC). Oil content, especially the oiliness gradation, is a key parameter for shale oil evaluation and numerous studies had...
