Abnormal pressures are encountered during exploration drilling in different parts of Krishna-Godavari Basin in the east coast of India. Nature and the stratigraphic occurrences of the overpressure zones vary across the basin.

The purpose of this paper is to relate diagenetic processes in deeply buried sandstones in the fourth member of the Eocene Shahejie Formation interval, Bohai Bay Basin, China, to pore-fluid flow changes with progressive burial.

The purpose of this study is to understand the hydrocarbon charge history of a tight gas reservoir and to provide a model for further exploration through an integrated study including x-ray micro-computed tomography and scanning electron microscopy imaging, natural gas and light oil geochemistry, and fluid inclusion petrography.

The mechanism for petroleum accumulation in the Qinghuangdao 29 oil field, Bohai Sea, China, is examined by analyzing the gas and fluid composition and conduit architecture and calculating the intensity of boundary faults in order to better understand petroleum exploration on the Shijiutuo uplift.

Carboniferous volcanic rocks of the Junggar Basin, China, are primarily andesite and tuff. Diagenetic processes that control reservoir quality are examined. The controlling factors for oil distribution in these volcanic rocks are faulting, fracture development, and degree of weathering.
