This study analyzed crude oils from the lower part of the third member of the Eocene Shahejie Formation (Es3L) and three prospective source rocks from the Shulu Sag, Bohai Bay basin, eastern China using a variety of organic geochemical methods. Biomarker characteristics were used to interpret source-rock organic matter input and depositional environment, and oil-source rock correlation.

The geochemistry and reservoir characteristics of the lacustrine shale in the Eocene Dongying depression are described in detail based on thin section and field emission scanning electron microscope (FESEM) observations of well cores combined with X-ray diffraction, physical property testing and geochemical indicators.

Variations in environmental and biological origins contributing to the heterogeneity of lacustrine source rocks can be illustrated in their diverse genetic facies. The Zhu 1 depression, eastern Pearl River Mouth Basin, South China Sea, is characterized by two thick Paleogene organic-rich syn-rift units, the Wenchang and Enping Formations.

Two hundred twenty five rock samples and thirty seven oil samples from the Beibuwan Basin, South China Sea, were analyzed with geochemical and organic petrological techniques to evaluate the Eocene lacustrine source rocks, and investigate controls on their properties and the distribution of different oil families in the basin.

The deep high-temperature, high-pressure Lower Cretaceous Bashijiqike sandstone (buried to depths as great as 6.5-7.1km) is an important natural gas reservoir in Keshen gas field, Kuqa depression of the Tarim Basin. Reservoir quality is a critical risk factor in the development of these ultradeep reservoirs.
