Why seismic sequence stratigraphy?
W. Wornardt Both exploration and exploitation programs can be greatly enhanced by applying seismic sequence stratigraphic analysis. It has dramatically increased the explorationist’s ability to interpret rock types associated with AVO anomalies and to predict hydrocarbons where AVO anomalies do not exist. This technique gives the explorationist the ability to recognize, discover and evaluate new hydrocarbon reservoirs and to reduce the risk in management’s decision making. The play concepts, source, seal and traps associated with different reservoir sands and their associated lowstand, transgressive and highstand systems tracts are an important aspect of this analysis. From an engineering perspective, seismic sequence stratigraphy can explain: Why one well has two pay sands, while another well in the same field has only one pay sand Why a waterflood does not work How to be more efficient in delineating and developing a new field. Seismic sequence stratigraphy analysis is the integratio
