The depositional environment of the Bigenerina humblei 1, Bigenerina humblei 6, and Amphistegina “B” 1 sands of the Hog Bayou field in Cameron Parish, Louisiana, was investigated. To complete the investigation, analysis of well log data, along with the preparation of structure, isopach, and fault plane maps, as well as cross sections, were completed for the four sands. Paleontological data and regional literature pertaining to deposition were also utilized.
The conclusions made for this study are based on interpretation of maps generated and the comparison of these maps with maps and models of modern day and ancient depositional environments. All of the three sands studied in the Hog Bayou field are concluded to be those that are representative of varying stages in the development of a deltaic environment. All information gathered and generated for the study area indicates depositional characteristics of distributary mouth bar, distributary channel fill, and channel complex sands. The Hog Bayou field is structurally based on growth faulting that interacts with many of the strata in the field. Growth faulting and its associated rollover anticlines prove to be the primary targets of hydrocarbon accumulations.
The conclusions made from this study can put to use in the interpretation of other analogous middle Miocene depocenters found along the Gulf Coast. The understanding of the depositional environment may ultimately lead to new discoveries in yet to be explored fields.
