This section summarizes the nature of cyclicity, controls on depositional patterns and the occurrence of hydrocarbons in Devonian and early Mississippian strata in the WCSB. These strata comprise a thick succession of shallow-water carbonates and basin-filling shales, limestones and evaporites. The foregoing account provides a sequence stratigraphic framework for these deposits. This framework was established through the recognition of cyclicity at a number of different levels. The first-order cycles approximate the group level stratigraphy of the basin. At a finer level, the use of the depositional sequences defined in this manual provides a higher resolution of correlation than can be attained from either biostratigraphy or seismic stratigraphy. The recognition of cyclicity allows for predicting depositional patterns at many different levels. The understanding of facies distributions in time and space is critical to successfull exploration. This is especially important in the Devonian and early Mississippian of the WCSB where the majority of hydrocarbon traps are stratigraphic in nature.
