Abstract

Reflection seismic techniques have a number of limitations to get suitable images in hard rock environment. Many seismic migration algorithms need to know the values of propagation velocity of acoustic waves. In sedimentary basins, where layers are usually continuous reflectors, that information could be obtained directly from acquired data, but there are many steeply dips and lack of the horizontal boundaries in hard rock media. In this way, the estimation of velocity model is a really difficult task. Here we describe the velocity-less pre-stack time migration in application to hard rock conditions and demonstrate the results on synthetic data.
