The Geological Survey of the Netherlands has a large archive with historical North Sea data. A vast volume of vintage seismic data recorded in the 2nd half of the 20th century is recorded on paper scrolls. These data are commonly of very high quality and can be the only available seismic information for particular areas. They give valuable insights into the geological architecture and distribution of sediment type in the North Sea subsurface. Over the past years, we scanned all paper sections to make them available for further digital processing. A method to transform these scanned images to a digital seismic format (SEG-Y) has been optimized and tested for several datasets. In the SEG-Y format the historical data now fit the “create once, use many times” principle and can easily be included in modern-day mapping and modelling programs. The aim for the near future is to make these datasets easily accessible for the public through our open-access portal, helping users in science, government and industry to increase their understanding of the North Sea.
