Almond Formation reservoirs in Canyon Creek and Trail fields: Paleostructural evolution of a tight-gas accumulation, by Brent Greenhalgh. This paper details a predictive model for the Almond reservoir sweet spots in the Canyon Creek and Trail fields. The techniques and concepts used in this study can be applied to any tight accumulation where the overprint of hydrocarbon migration, structural evolution, and reservoir degradation are operative.

Integrated and improved direct hydrocarbon indicators: A step forward in petroleum risk discrimination, by P. W. Monigle, T. S. Hedayati, and F. J. Goulding. A significant challenge to predictability between success and failure in petroleum exploration involves reconciling contradictory information between geological and geophysical observations. Applying a new integrated workflow, allows for integration of all observations into a single chance of success value in a simple, repeatable manner.

Coexistence of coalbed methane, shale gas, and tight sandstone gas in coal measure strata: A case study from the southern Qinshui Basin, China, by Lianbo Zeng, Yunzhao Zhang, Yongchen Li, Xiaoyao Wang, Jinxiong Shi, and Shaoqun Dong. Recent exploration has revealed the coexistence of coalbed methane, shale gas, and tight sandstone gas within the coal-bearing strata in the Qinshui Basin, China. This study will enhance unconventional gas utilization and provide a theoretical foundation for understanding the compatibility of superimposed gas-bearing systems in coal measure strata.

Seismic-constrained reservoir modeling and simulation for CO2 sequestration potential assessment of the Arbuckle Group: Wellington field, Kansas, by Abidin B. Caf, Matthew J. Pranter, Zulfiquar A. Reza, David Lubo-Robles, Heather Bedle, and Kurt J. Marfurt. The Arbuckle Group in the Wellington field in Kansas has recently been a focal point for CO2 geosequestration feasibility studies, mainly through petrophysical, geophysical, and geostatistical modeling methods. The workflow described in this paper created three-dimensional reservoir models that show stratigraphic variability of subsurface properties in greater detail and further reduce the subsurface uncertainty in the study area.

Regional productivity in the Austin Chalk, with emphasis on fault zone production in the Karnes trough area, by Frank Male and Chris K. Zahm. Despite the several thousand horizontal wells drilled in the Austin Chalk, regional productivity analyses are limited. This study incorporates recent production trends and includes recent completion techniques within the Austin Chalk play in Texas. The authors also investigated the Karnes trough fault and fractured trend to determine potential influence on productivity.
