My research interests have focused on the sedimentology, stratigraphy and reservoir characterization of fluvial and shallow marine depositional systems and the potential effects of sedimentological heterogeneities at a variety of spatial scales on fluid flow. I am interested in understanding the 3D variability within modern and ancient sedimentary systems and relate that to controlling factors. This understanding, in combination with forward modelling simulations, is used to predict subsurface property distributions and related uncertainties.

MSc at Utrecht University, The Netherlands (sedimentology and palaeoecology of macrofauna invertebrates)

PhD at Technical University of Delft (fluvial reservoir characterization)

My full time job is with Equinor ASA as Specialist Sedimentology and Stratigraphy. I am based in Trondheim, Norway

I am a sedimentary geologist working the interaction between hydrodynamics, surface dynamics and subsurface preservation forced by past, present and future climate change. I feel strongly committed to apply our knowledge of sedimentary systems to improve our understanding and prediction of the impact of climate change on both natural and urbanised areas. My research focuses on deltaic, coastal, lacustrine and fluvial systems and how they respond to imposed changes in river discharge and sealevel (climate-driven). I favor a combined approach of numerical simulations and sedimentological and geophysical field data analysis, generally from both present-day systems (e.g. Kangerlussuaq Fjord (Greenland), Strynvatnet (Norway), Lake Turkana (NE Africa), Caspian Sea, Adriatic Sea, Mahakam delta (Indonesia), Golo delta (France) and from various outcrop locations. By combining modelling and field research more can be learned from both worlds. I collaborate nationally and internationally with Universities, Research Institutes and companies

Deyan is associate professor at Delft University since 2019, although he has been appointed to this university since 2008 on two research grants and as an assistant professor.

He does this with physical arrivals retrieved by seismic interferometry, but also with non-physical arrivals, which result from non-compliance with the assumptions needed for application of seismic interferometry. Currently, Deyan Draganov is co-supervisor in one Ph.D. project in Delphi and he is eager to bring his expertise on seismic interferometry in the Delphi consortium.
