The Way to a Clearer Seismic Image: An Integrated Approach in South Tunisia Ghadames Basin
- 611 Downloads
In order to unlock the remaining exploration/appraisal potential within South Tunisia Ghadames Basin, OMV adopted an integrated approach focused on the enhancement of the seismic image. One of the crucial reservoir imaging challenges is the attenuation of the interbed multiple energy which is hampering the seismic image at both shallow and deep targets. The approach focused on optimizing a seismic data acquisition design as well as applying advanced/customized processing workflows. The QC of the final product with the synthetic well trace showed that the method adopted so far is the most efficient way to clean the seismic dataset from multiples.
