Abstract

Practical application of traveltime inversion on multi 2D seismic surveys is limited by difficulties to be confident of the final velocity-depth model reliability due to a lot of mis-ties. An integrated approach combining seismic interpretation techniques and seismic processing like traveltime inversion and depth migration is developed in order to improve the geological and geophysical consistency of results. This approach is characterized by the use of coherence criteria firstly applied to each 2D seismic profile and secondly extended to 3D structural analysis. Consistency control procedures are described using examples deduced from multi 2D dataset study recorded in the Paris Basin. The objective is then to obtain accurate layer velocity estimates and reliable time to depth conversion of seismic sections.
