"Most of the worlds largest oil fields are stratigraphic traps."
huh ? ghawar and burgen ,numero uno and dos, are certainly not stratigraphic traps. and you may be correct on the basis of the distribution of fields over a certain size, but this statement does not fit with my understanding. could you point me to a study that shows that most of the world's largest fields are stratigraphic traps ?
