Sandstone depositional models for exploration for fossil fuels
This syllabus is intended as a brief summary of the depositional processes, Holocene sediments, ancient counterparts and examples of stratigraphic traps in five depositional environments. The emphasis of this syllabus is the understanding of five types of sandstone depositional models which are proven to contain reservoirs of petroleum and natural gas, and also to contain uranium deposits. These five types are: (1) fluvial sand body model; (2) beach and barrier island sand body model; (3) tidal flat and tidal sand body model; (4) deltaic sand body model; and (5) turbidite sand body model. Both the geological and geophysical criteria that will permit recognition of such sand bodies as potential stratigraphic traps for exploitation and production are developed. The outline to be followed is relatively simple. Each section begins with a discussion of Holocene sediment deposition processes where such sand bodies evolve. Next, the sedimentary criteria and geometry of each of these sand bodies are reviewed from Holocene sediment data. Third, examples of ancient counterpart sandstone bodies are presented. Each section closes with a very brief review of examples of oil field and uranium deposit case histories. Electric log and seismic characteristics of some of these sand bodies are reviewed in the applied section of each chapter. The models reviewed here are of world-wide occurrence and importance for hydrocarbon and uranium exploration, although the majority of examples discussed are from North America.
