Abstract
Estimation of pressure and saturation changes from seismic data is an important step in reservoir characterization and planning of future IOR programs. In addition to estimating such reservoir property changes, the assessment of the estimation uncertainties is important for risk assessment and quantitative integration of observed and modelled data in reservoir model updating. This paper describes a quantitative petro-elastic inversion approach that determines pore pressure and saturation changes from inverted seismic data and assesses the asociated uncertainties. An application to a field where repeated saturation logs are available demonstrates its applicability and correctness.
