Depositional Systems (An Overview)
Within the realm of terrigenous clastic depositional systems there exists a broad spectrum of varying depositional environments. Because of physical limitations and the scope of this study, only shelf and shoreline depositional systems will be examined. Therefore, emphasis is placed in this short course on Barrier Island, Tidal Inlet, Shoreface and Inner Continental Shelf Sand bodies in both deltaic and non-deltaic settings.
Figures & Tables
This lecture course is designed to provide geologic insights towards the development of depositional and exploration models for sandstone reservoirs associated with one or more of a variety of shelf and shoreline environmental settings. Sedimentologic and stratigraphic criteria will be utilized to more accurately predict the subsurface distribution and trend of reservoir quality sandstones. These criteria include a number of basic geologic “tools” such as well logs, cores, outcrop, seismic, and isopach and structure maps, all of which will be utilized in varying degrees during this course. Equally important in the development of models for shelf and shoreline sandstones is the subsurface analysis of modern depositional systems. An understanding of the three dimensional framework of modern clastic sedimentary environments is critical to the proper interpretation of vertical sequences, lateral facies relationships, sand body geometries and inhomogeneities of sandstone reservoirs.
