Resumen
With the advancement of hydrocarbon exploration, the oil industry has been searching
for ways to minimize exploratory risks, with one of these ways being the improvement
of the used tools. There are three steps in this exploration: the seismic data acquisition,
the seismic processing and seismic interpretation. This work is part of the seismic processing,
more specifically of one of its stages, the seismic velocity analysis, which aims to
find the seismic velocity field that offers reliable earth subsurface models through known
algorithms of velocity analysis. One of the objectives of this work is the creation of tools
to facilitate this velocity analysis by implementing these algorithms so that they work
integrated in a single platform of analysis. Another point that this advance brought, was
the considerable increase in the volume of seismic data acquired, which led to an increasing
need of computer processing power. Given this need, we present a methodology for
velocity analysis using GPUs and its results, showing the viability of using it to accelerate
Geophysics algorithms, particularly algorithms for velocity analysis. Finally, case studies
will be presented, showing the performance results of the algorithms in CPU and GPU
versions.
