Abstract
Seismic reservoir characterization within the pre-salt carbonate context faces two challenges. One is that the data quality, resolution and amplitudes reliability might not be good enough to let classical approach working. Second is that although Ip-Porosity or Ip/Is- Ip laws are often used to interpret the seismic as a porosity or a geological facies indicator of the reservoir, carbonate rocks rarely follow a simple relationship. That being said, seismic is the main tool for the petroleum explorationist and should be used to derisk presalt exploration or optimize appraisal campaigns. Well will expose some lessons learned from different approaches that we used in seismic reservoir characterization in the pre-salt domain.
