White<ref name=ch04r112 />) compiles data on the depositional setting of more than 2000 major oil and gas fields in 200 transgressive and regressive wedges within 80 basins. With clearly stated qualifications, White shows that most hydrocarbons found in siliciclastic reservoirs occur in the base to middle of the wedge in generally lowstand to transgressive depositional facies. This can be attributed to the greater probability of effective top seal in contrast to the highstand systems tract. By using the stratal stacking pattern, supplemented by lithofacies and biofacies data, depositional environments can be properly identified and paleogeographic maps constructed for each systems tract to predict between and beyond data points.
