Joost received his PhD from the Delft University of Technology for his research on interferometric redatuming of seismic data by multidimensional deconvolution. During his studies, Joost visited several institutes, ranging from the Indian School of Mines in India to St. Petersburg State University in Russia, via universities in Utah, Texas, Colorado and British Columbia. He also collaborated closely with Shell, PGS and Saudi Aramco.

 

Clearing Method

Research

Currently, Joost focuses on seimic imaging with multiply reflected waves, using recent insights from and beyond seismic interferometry. His goal is to integrate these insights with a novel inversion scheme to transform conventional data, recorded with sources and receivers at the earth's surface into virtual data as if sources and receivers are locally surrounding a selected target zone in the subsurface. After this transformation, the target zone will be illuminated not only from above, as in the original data, but also from below. This transformation from so-called one-sided illumination into two-sided illumination is likely to improve resolution and constrain the inversion of seismic data for rock and fluid properties.

Various other benefits are obtained as well:

  1. As multiply reflected waves are exploited, shadow zones that can not be seen with primary reflected waves can now be illuminated.
  2. After transformation, the data volume is reduced, saving dramatically on computational resources during further processing.
  3. If a shallow section of the subsurface is strongly heterogeneous, wave propagation through this section can be eliminated from the seismic data by generating virtual sources and receivers below it.
  4. Changing rock and fluid properties can be monitored locally in the target zone, independent of changes that occur elsewhere in the subsurface.
