Reverse Time Migration (RTM)

Conventional wave equation migration is performed by propagating data downward through a velocity model into the earth and is limited where the structure and velocity field generate more complex arrivals, such as turning and 'prism' waves. Complex propagation paths give rise to arrivals that are seen as noise in the imaged data.

RTM propagates events both downward and upward through the earth model, explicitly handling turning waves and all other complex propagation paths. In many cases the ability to make use of these complex wave modes allows imaging of parts of the subsurface that otherwise have poor direct illumination.

Campos Basin TTI RTM


  • Imaging of all possible arrivals
    • Superior multi-path imaging
    • No dip limitation
    • Accounts for extreme lateral velocity variations
  • Wide azimuth and TTI capable
  • Mirror migration of ocean bottom or VSP data
  • Correct for amplitude anomalies using Q-compensating RTM.


  • Improved imaging of complex plays
    • Steep dips
    • Complex overburdens, regardless of dip or rugosity
  • More accurate focusing, positioning and amplitudes in complex areas
  • Inclusion of TTI produces high-fidelity velocity models
