The source rocks in the Bohai Sea area have been systematically examined, and the expulsion history of hydrocarbons in different sags has been simulated. Source rocks formed in deep lake facies have higher levels of organic matter and have better hydrocarbon generation characteristics.

Differences in hydrocarbon chemistry between the western and eastern portion of the Tazhong Uplift, Tarim Basin, China, are mainly the result of thermochemical sulfate methane with sulfate contact ion pairs in the west and thermal cracking of liquid hydrocarbon in the east.

Four seals and five pressure systems are recognized in the Sichuan Basin, southwest China; Based on mechanisms analysis and hydrocarbon generation history, a pressure evolution model has been constructed which includes a normal pressure stage, an overpressuring stage, and an overpressure releasing stage.

Organic-rich shale and siliceous shale that was deposited from suspension near upwelling zones are key exploration targets for shale oil and gas in the southeastern Sichuan Basin, China. Seven lithofacies have been identified, and turbidity current mudstones are the principal exploration targets for tight oil.

Kela-2 is a giant gas field with a proven reserve of 597 tcf in the Kuqa depression, northern Tarim Basin. Widespread overpressures have been encountered in the Eocene and Cretaceous sandstone reservoirs of the field, with pressure coefficients up to 2.1 from drill-stem tests and well-log data analysis.

Bulletin Discussion

 
Zheng et al. provide evidence based on facies, geometry, and sandbody orientation and thickness that the incised-valley fill mentioned by Jiang et al. (2012) is in actuality a barrier island. Jiang et al. offer additional proof based on core, well logs, thin section, field study, seismic analysis, and well correlation to reinforce their original interpretation.

Bulletin E P Note

 
Structures related to the Penglai 19-3 and 25-6 fields are fault restraining bends produced by dextral strike-slip movement on faults within the Tan-Lu fault zone, east China. These structures formed after deposition of source rocks and are favorable locations for hydrocarbon accumulation.
