Seismic acquisition
 
Land acquisition
  • 2D Seismic Reflection
    • Very High Resolution Seismic : sampling of ¼ to ½ ms, intertrace between 1m and 5m
    • High Resolution Seismic : sampling of 1 ms, intertrace between 5m and 20m
    • Conventional Seismic : sampling of 2 to 4 ms, intertrace between 20m and 100m
    • Crustal Investigations / ECORS
  • Seismic Refraction
  • Mini-VSP (Vertical Seismic Profile)
  • Drilling
  • Topography
  • Real-time quality control acquisition

    • Equipment

  • EOSYS uses
    • a 24 bits POLYSEIS laboratory (IFP trademark), 460 numeric channels with radio or line transmission
    • a SERCEL SN338 HR with 96 channels lab.
    • Sources : in house portable vibratory source (depth 5m to 500m), truck mounted vibratory sources, dynamite
    Seismic processing
  • 2D/3D and VSP Processing
  • Transcoding, transcription and reading of old tapes (21 tracks and 9 tracks)


    • Equipment
  • Landmark PROMAX processing software allows 2D, 3D and mini-VSP processing
  • Silicon Graphics O2 and IBM RS/6000 workstations are used in the processing centre.
