Analyses of Clastic Depositional Systems and Sequences

Clastic Depositional Systems owe most of their diversity and heterogeneity to the many different geologic processes that control their formation and give rise to the characteristics of the resultant sedimentary environments. Clastic depositional systems cover different environment ranging from the non-marine to the marine environment. In nonmarine environments the systems constitute the fluvial alluvial eolian and lacustrine sub-environments whereas in marine setting the systems cover deltaic shallow marine and deep marine settings. The aim of this work has been to demonstrate the effectiveness of geophysical approaches to accurately resolve subsurface geology in the absence of geological data. This work also contributes significantly to a wider spatial analysis of subsurface geology through seismic interpretation which is normally limited in space by the conventional one dimensional core analysis. In addition electrosequence analysis provides extra subsurface geological information which is useful in the accurate prediction of possible target and reduces exploration risk invariably.
