Full wavefield AVO inversion

Commercial highlights

  • released in 2024

Client value

  • dispersion time depth relationships accounting for dispersion
  • improved reservoir characterisation in the presence of short period multiples, mode conversion, dispersion and attenuation
  • can be applied to both new and legacy data

Technical highlights

  • fast, accurate, flexible forward model
  • 1.5D approximation to elastic full wavefield inversion
  • inversion uses all the energy in the gather to estimate the true subsurface properties
  • demonstrated in land and offshore settings and on 2D & 3D and PP/PS data
  • outputs available in seismic and elastic property domains

Full wavefield AVO (FW-AVO) - A technical description

Qeye’s FW-AVO is a fast, accurate and flexible forward model of the full 1.5D elastic wavefield including all requested multiple modes, mode conversions, attenuation and dispersion effects. Critically, it is formulated such that it can be applied directly to the seismic data in the inverse sense to yield outputs in the seismic amplitude and/or elastic property domain.
