Abstract
In this project, new formulas for residual moveout of migrated reflection events will be developed. They aim to quantify errors in the velocity field and, in a further step, update it. This work is an extension of a previous one developed with Jörg Schleicher (DMA/IMECC/UNICAMP), which results were submitted for publication (Schleicher and Biloti (2004)). Algorithms for velocity update ba…
