The evolution and characteristics of the time-to-depth conversion method of time-migrated data that has been used successfully at Petrobras for the last 20 years is described. Such methodology is primarily based on the image-ray concept, but also int

We developed a strategy for automatic Semblance panels pick, that uses Genetic Algorithm optimization method. In conjunction with restrictions and penalties set from a priori information it’s obtained as a result a nonlinear fit of time interval ve

The representation of compressional seismic waves velocity fields from geological models through numerical parameters has a strong geophysical importance, because, it makes possible to quantify such qualitative models, allowing its mathematical manip

In this work, based on the theory of modal propagation of acoustic energy in deep oceans and using the analogy between acoustics and quantum mechanics, we show that it is possible the existence of almost dispersionless Airy beams propagation at great

In this work we present an alternative migration velocity analysis strategy that uses pairs of delayed stacks to estimate velocity field. The method involves the migration of two delayed stacks (p and ‐p slowness), using the reverse time migration

We developed a strategy for automatic construction of the stacking velocity field. This strategy is divided into two steps. The first step performs the automatic pick in Semblance panels through the Genetic Algorithm optimization method. In conjuncti
