Abstract

Summary

Interpretation of subsalt targets is often very challenging in insufficient illumination zones where the weak signal is hidden under strong coherent noise. To remove the noise and improve interpretability, we developed a geologic-structure based image enhancement technique. Originally designed for reverse time migration vector image partitions, our technique is now applicable to any image by decomposing the image to directional components. A novel automated selective stack is further introduced to improve the result and allow flexibility for different requirements of the enhancement. Real data examples clearly show significant improvement in the subsalt image, for both general purpose amplitude-friendly noise removal, and targeted structural interpretation purpose harsh enhancement that reveals subsalt events masked by noise.
