A method and system for seismic data processing utilizes azimuthal variations in the velocity of seismic signals. The woven fabric of carbon fibers is impregnated with a binder, in particular with a resin, to form a binder-impregnated fiber material. A probabilistic joint inversion is applied on the TD-CSEM data and the further data to produce a model representing a subterranean structure that is a target of the subterranean survey. The hydrosilylated polymer is obtained by reacting at least one hydridosilsesquioxane compound of the following formula :.
