Of basic importance to an under standing of these strata is an outline of the sedimentation involved and a comprehensive division of the sedimentary facies present. Accordingly, we must recognize such qualifying features as the paleogeography, the average high-tide level, sea level and wave-base level during each portion of the geologic time under discussion. We suggest that the sed imentary rocks of the Carboniferous and Permian Systems can be divided into 3 major facies and 13 minor facies. The major facies are divided into those that accumulated in a regime, those that were deposited near the shoreline, and those that formed in a carbonate platform environment. The continental rocks include volcanic facies, eluvial facies, and fluvial-plain facies. Those deposited near the shoreline include shore-plain facies, shoreside tidal-flat facies, shoresideshoal facies, and shoreside-basin facies. Strata formed in a carbonate-platform environment include platform basinswamp facies, platform-flat facies, platform-depression facies, platform-bank facies, platform-reef facies, and platformbasin facies. In order to assess how these facies relate to favorable zones for oil and gas development, we must consider the following three aspects: Some sedimentary facies are favorable for oil and gas generation; other facies are favorable for the accumulation of hydrocarbons; and other facies are favorable as oil and gas reservoir rocks. Finally, prospective regions for oil and gas production must be analyzed according to the distribution of favorable facies for oil and gas gen eration, accumulation and entrapment in combination with conditions of regional conservation.Read More
