Technical Paper: Reducing Pitfall Risk Using Seismic Inversion and Rock Physics Analysis

Society: SBGF
Paper Number: 2949
Presentation Date: 2011


Four Partial stacked time migrated seismic data were inverted for absolute and relative impedance and Vp/Vs ratio, generating also as additional results Poisson ratio and Shear Impedance. Additionally, rock physics analysis using available well logs was made trying to discriminate oil from background (water sands and other lithologies). Integrating both information, it was possible to discriminate amplitude anomalies related to oil saturation from lithologic anomalies.

Technical Paper presented at the 12th International Congress of the Brazilian Geophysical Society, held in Rio de Janeiro, Brazil, August 15-18, 2011.
