Non-Linear AVO Inversion

Technical Aspects

Non-Linear Inversion Overview

  • All terms O(2) in r.p. contrasts

(i.e.  DVp/Vp, DVs/Vs, Dr/r, (DVp/Vp)2, (DVs/Vs)2, (Dr/r)2

DVp/Vp * DVs/Vs, DVp/Vp * Dr/r, DVs/Vs,* Dr/r
  • Accuracy/stability of AVO parameters/rock property contrasts
  • Handle larger rock property contrasts
  • Handle larger angles of incidence
