Abstract

We describe here the interpretation done for the appraisal of a CO2 geologic storage site in a saline formation in the Duero basin, Spain. This interpretation was done in two phases: (1) using 2D data only, (2) using 2D data plus newly acquired 3D data. As a result, this project was ideal to observe what the added value of 3D data was: fault and horizon mapping were improved, formation thickness was better constrained, geologic prognosis was more accurate and small faults could be mapped in the overburden. We also discuss how our seismic interpretation had to be used in the frame of CO2 storage: risks on containment, compartmentalization, and structural uncertainty were better evaluated.
