C021 Stereotomographic picking in practice Abstract 1 GILLES LAMBARÉ* MATHIAS ALERINI 1 PASCAL PODVIN* *École des Mines de Paris France 1 Sintef Petroleum Research Trondheim Norway Stereotomography allows estimating velocity macro models from seismic reflection data. Compared to travel time tomography the specificity of the method is that it considers locally coherent events. As a result Stereotomographic picking is easier and leads to a much denser coverage of the model. Several applications have demonstrated the efficiency but also the principal difficulties of the approach : regularization and picking. For picking in order to retain the efficiency of the method we
