Higher-Resolution Determination of Zero-Offset Common-Reflection-Surface Stack Parameters

Higher-Resolution Determination of Zero-Offset Common-Reflection-Surface Stack Parameters

We developed a higher resolution method for the estimation of the three travel-time parameters that are used in the 2D zero-offset, Common-Reflection-Surface stack method. The underlying principle in this method is to replace the coherency measure performed using semblance with that of MUSIC (multip...
