Popis:	Depth migration of seismic data is becoming more routine for imaging of complex geological structures. However, in some cases, the quality of the resulting depth section is lower than expected. A typical case is in imaging of salt bodies. The seismic images of steeply dipping salt flanks are frequently broken, smeared, and difficult to interpret. The study presented in this paper demonstrates one source of this imaging problem, and suggests a solution we call controlled stacking. The core of the solution is the correct muting of partial images produced by prestack depth migration (preSDM) before sorting and stacking to obtain the final depth section.
