Abstract

Recently global approaches have been developed to compute geological models directly from seismic data. The present paper proposes to adapt on a large data set the method based on the minimization of a cost function developed by Pauget et al, 2009. This seismic data-set presented is a merging of several seismic blocks, located in the Gulf of Gabes off-shore Tunisia. The proposed workflow aims to compute separately geological models on fifteen individual sub- blocks. The interpretation of each sub-blocks produced independent geological models. The sub models were then synchronized using the same global approach but at the scale of the whole area. By this way it provides a large scale geological model with the same level of accuracy obtained on the sub blocks. Such result and approach can be used for the regional interpretation and push back the frontiers of the seismic interpretation for large volumes. Stratigraphic as well as a structural interpretations were achieved on the whole area. It enhanced new features in the existing reservoir in production and helped in the regional understanding of the geology.
