Abstract
If lateral velocity variations are generated by tectonic and structural features, the subsurface is considered as seismically complex structure due to perturbed propagation of seismic waves in geological layers. In this case, time seismic sections are very distorted and application of depth migration, requiring a structural depth model, is necessary to obtain seismic images according to geological reality. ``Integrated structural interpretation`` is the method combining seismic and geological techniques and data in order to determine a structural model and the associated seismic depth image. The subject of this thesis is the building of a structured method of integrated interpretation by working out of coherent sequences and plans. The first step is the study of the system integrating data and actions: links between all the forms of structural models and between data and seismic techniques (processing and interpretation) are described. Based on this schematic organization and on results of four real case studies, coordination of seismic and geological techniques is done in three sequential phases, from global geological study to structural details understanding. We conclude that analysis of geological assumptions is essential because they are used to control and validate the method to obtain a geologically and geophysically consistent result. (author).
