Gan, S. (author), Wang, S. (author), Chen, Y. (author), Qu, S. (author), Zu, S. (author)Direct imaging of simultaneous-source (or blended) data, without the need of deblending, requires a precise subsurface velocity model. In this paper, we focus on the velocity analysis of simultaneous-source data using the normal moveout-based velocity picking approach.We demonstrate that it is possible to obtain a precise velocity model directly...journal article 2016
