Course Content

Geophysical challenges in presalt plays are significant from acquiring the right data, imaging, to property estimation of the subsurface in presalt environment. The presence of complex geology due to salt, carbonates, and basalts leads to complex wave propagation recorded in the seismic data. It is crucial to understand reservoir depositional systems, petrophysical properties, and seismic imaging issues to increase the efficiency of exploration and development activities and production strategies to maximize recovery. The focus of this workshop is to discuss latest geophysical ideas, and industry practices from locating, imaging to characterizing the reservoir.
