Geologic Building Blocks for Reservoir Characterization - Lessons Learned from the Permian Brushy Canyon Formation, West Texas

Accurately imaging the architecture of a hydrocarbon reservoir requires populating the three-dimensional space with the sediment bodies that compose it. But what scale geologic building block is best for constructing a reservoir architecture? Should one start with smaller facies, or use larger sediment bodies, representing architectural elements, or should one focus on even larger stratigraphic packages that are more easily resolved on subsurface analog data? Strategies used to characterize reservoir architecture are generally based on the scale of investigation. If the problem is small, then the focus is narrow.
