Case History

Numerous successful wells were drilled as the result of applying iDEPTH, iTOMO and iPRIM methodologies, tying wells and improving images. The key was the regional calibration of seismic velocities with well data early. As suggested in the following figure.

Case history

Regional calibration using all available wells in a survey area can provide geologically feasible velocity heterogeneity and filter out blunders in velocity analysis. It provides eventually the best PSDM images.

Case history  

Then reflection tomography can estimate heterogeneity first before estimating anisotropy. Practical solutions for tomography can solve depth imaging problems with automated procedures.

Case history

Anisotropy parameter estimation, residual focusing and de-stretching can improve imaging for interpretation and prospect evaluation.

The following case study has shown that SeisLink velocity packages have proven to be the best “mouse trap” for finding oil and gas prospects and reducing risks.
