FOCUS

FOCUS on Upper Jurassic sandstones

Publieke samenvatting

This project aims to update and increase our knowledge of the distribution and stratigraphic architecture of hydrocarbon reservoirs in the Upper Jurassic to Lower Cretaceous successions of the Dutch sector in the Central Graben area. Exploration efforts that focus on this stratigraphic interval are often hampered by the erratic and unpredictable distribution of reservoir sands. Moreover, production estimates still suffer from significant uncertainties, in the absence of well-constrained stratigraphic models for these active fields.

The integration of sedimentary facies analyses and detailed biostratigraphic and stable isotope analyses, in combination with a fit-for-purpose outcrop-analogue study, is expected to increase our understanding of these complex depositional systems. Important deliverables of the study will consist of a series of conceptually updated and stratigraphically realistic models of facies distributions, as well as stratigraphic trends in the interval of interest.
