A quarter of them are producing petroleum Before exploitating in a new area attemting to locate drillabe prospects it is necessery to establish the type of basin what productive horizons it may contain and where they may be broadly located Even though petroleum reserves can be found in rocks of all ages most giant fields and most of the world s reserves occur in sequences of Late Mesozoic and Cenozoic age Figure .
