SUMMARY A carbonate play is the juxtaposition of a limestone or dolostone reservoir facies sealed by a carbonate or shale facies, with its hydrocarbons sourced from a nearby organic-rich carbonate or siliciclastic mudstone. Understanding the controls on carbonate play type distribution and geometry is critical to more successful exploration in any basin. As such, delineating potential carbonate plays from seismic or wireline logs requires a sound understanding of the depositional and diagenetic controls that create the reservoir facies, but it must be obtained within the context of geological age and physiographic setting. Specifically, one must appreciate the environmental controls on carbonate facies development, and potential pathways for diagenesis and porosity evolution. For this reason, strategies employed in the search for sandstone or mudstone reservoirs never work for carbonate sequences, including application of sequence stratigraphic models that assume sea level changes overridingly control carbonate facies and sequence evolution. This one-day short course reviews the key controls on carbonate facies occurrence and distribution, and demonstrates the strong influence of physiographic setting, both at the global and local scale. Because most carbonate reservoirs were developed within tropical or subtropical settings, paleotrade winds often were a major influence on their occurrence and distribution. In addition, the key controls influencing limestone diagenesis and dolomitization are reviewed, but with focused emphasis on how porosity and permeability evolve. The diagenesis discussion also will stress how to resolve the relative timing of secondary porosity development in these carbonates, which is key to exploiting regional porosity trends. The diagenesis discussion will further evaluate the role that deep-seated faulting often plays in carbonate diagenesis and development of reservoir quality, as well as hydrocarbon entrapment. This short course culminates with a discussion relating carbonate play type occurrence, geometry and distribution to geological age, but in the context of physiographic setting (platform versus ramp). This approach will be supported by case studies from different basins, and then applied to Paleozoic play type examples from West Texas and New Mexico.
