Morphology and depositional facies of the Pennsylvanian Claytonville (Canyon lime) field, Fisher County, Texas, by Travis Moreland, Alexander Gonzales, and Lowell Waite. The Claytonville field, located in Fisher County, Texas, is a large Pennsylvanian carbonate buildup along the western margin of the Eastern shelf (Midland Basin). The authors present wire-line log, whole-core, and three-dimensional seismic data to characterize and interpret the facies and overall morphology of the Claytonville buildup.

Predicting the occurrence and development of regionally extensive sublacustrine fans in the Oligocene Bohai Bay Basin: From sequence stratigraphy to source-to-sink systems, by Changgui Xu, Chenglin Gong, Ronald J. Steel, Xintao Zhang, Dayong Guan, and Dongwei Li. Three-dimensional seismic and borehole data were used to interpret sequence stratigraphic frameworks of the Oligocene Dongying Formation of the Bohai Bay Basin and to predict the occurrence and development of volumetrically significant sublacustrine fans developed in the established sequence stratigraphic framework.

Scanning electron microscopy of tight oil reservoirs before and after low-temperature hydrous pyrolysis, lower Permian Wolfcamp shale, Delaware Basin, Texas, by Wayne K. Camp, Michael D. Lewan, Marvin Floyd, and Tim Ruble. Scanning electron microscopy images were acquired from core samples before and after low-temperature hydrous pyrolysis representing a variety of rock types from productive tight oil reservoirs of the Wolfcamp shale in the Delaware Basin, Texas. The results demonstrate the ability of this method to characterize potentially producible oils from a variety of lithologies.

Asphaltenes in petroleum generation and correlation: Example from the hypersaline Qianjiang shale in Jianghan Basin, China, by Yuanjia Han, Dongqi An, Zhiliang He, Shiqiang Wu, Gangtian Zhu, Sheng He, and Nicolaj Mahlstedt. In this study, the authors compared the pyrolysis yields and phase kinetic differences of a pair of Qianjiang shale samples previously classified as source-rock and hybrid source-reservoir samples, respectively, to provide new insights into the use of asphaltenes in petroleum generation and source correlation.

Cretaceous sequence stratigraphy and gross depositional environments, Browse Basin, Australia: Implications for the extent of petroleum systems and plays, by Stephen T. Abbott, Emmanuelle Grosjean, Dianne Edwards, Nadege Rollet, Tehani Palu, and Megan E. Lech. The Cretaceous fill of the Browse Basin hosts the producing Ichthys-Prelude gas field and several subeconomic gas and oil fields. Using seismic surveys and 31 wells, and an approach that integrates the interpretation of gross depositional environments within a sequence stratigraphic framework, the aim of this study was to determine stratigraphic relationships between source, reservoir, and seal petroleum play elements.
