RESUMO:

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.
