| Popis: |
First break times (FBT) of P-wave and S-waves picked from three-component (3C) VSP data were used to produce tomographic velocity profiles and Vp/Vs ratio distribution. 3C Eigenvalue rotation is critical for correctly identifying and accurately picking FBTs of S-waves. The resultant tomographic images provide important information for formation evaluation and produce suitable velocity models for improving migration imaging of subsurface structures. |
