In this paper, we propose accelerating the process of seismic modeling on the Groningen...

... When seismic data are acquired over an irregular topographic surface, honoring topographic variations poses challenges to existing modeling algorithms. To deal with the challenges, the mesh-free scheme is introduced to seismic modeling with surface topography because of its two advantages. First...

... Generating seismic modeling software is a prime activity in exploration seismology as it plays an important role in almost all its aspects such as data acquisition, processing, interpretation, and reservoir characterization. The need to write high performance code is inevitable, even though...
