Paleobiology as a driver in exploration activities ///

The main exploration objectives in the Netherlands are Permian gas reservoirs, but hydrocarbons occur in almost all stratigraphic intervals. However, after roughly 50 years of extensive exploration, the Dutch on- and offshore form a mature exploration area. New play development concepts rely on the integration of existing information and innovative techniques. The Upper Jurassic to Lower Cretaceous strata have been a target for oil and gas exploration in the Netherlands for several decades. During the initial stages of Dutch offshore exploration history, various oil fields and some gas fields were discovered, of which only the F3-FB Field proved to be economic. In the Dutch northern offshore, uppermost Middle Jurassic (Callovian) to lowermost Cretaceous (Ryazanian), or the so-called Upper Jurassic, strata are limited to the Central Graben and Terschelling Basin, Fig. 1. The geology of these non-marine to shallow marine strata is complex, with a combination of lateral facies changes, repetitive log and facies characteristics...
