Workshop 1

Seismic Marine Sources: State of the Art

Sunday 4 June 2023



  • Christopher Walker (BGP Offshore)
  • Edward Hager (Shearwater GeoServices)
  • Luca de Vincenzi (Ocre Geosciences Services)
  • Nicolas Tellier (Sercel)
  • Xander Campman (Shell)



A new focus within marine sources is yet drawing ever-increasing expectations in the industry to meet key evolutions in offshore seismic acquisition. The environmental impact of sources requires due assessment and mitigation measures, lower frequencies are more than ever expected, and the final application steadily transitions from hydrocarbons to new energies. This workshop intends to draw a state of the art of existing and expected solutions to address at best a changing environment.


Participant Profile

The target participants include (but not limited to):

  • Geoscientists
  • Acquisition specialists
  • Exploration managers
  • Researchers who have an interest in new advancements on marine seismic sources and their applications
