Abstract	In spite of the unfavourable oil price, the interest in unconventional shale oil resources has caused a resurgence of activity in mature hydrocarbon-bearing basins in China. In the evaporate dominated Jianghan Basin, for example, historical conventional plays have focused on clastic reservoirs, and heritage fields now face production declines. Along with the successful commercial development of Silurian Longmaxi Shale in Fuling, the largest marine shale gas plays outside North America, rapid advancement has been achieved in many facets of completion and drilling technology targeting shale dominated strata. This has laid solid foundation for turning the focus of oil exploration and production activity towards the intersalt hypersaline lacustrine dolomitic shales in the Eocene-Oligocene Qianjiang Formation. Given the relative infancies of these shale oil plays, lack of stable long-term production, uncertainty in estimation of oil reserves in these unconventional plays, and complexity in the lithofacies of inter-salt shales, a regional assessment has been undertaken at Sinopec to further our understanding of the stratigraphy and depositional environment of these plays in an effort to decrease shale oil exploration risk. In this contribution, we present both inorganic and organic geochemical data to constrain the stratigraphic framework, lithofacies variation and depositional environment of the inter-salt shales in the Qianjiang Formation.
