Latest Patents

Marie-Lise Bernard holds a patent for a method of joint inversion of seismic data represented on different time scales. This invention involves constructing an image representative of a heterogeneous medium by sequentially inverting seismic data. The process determines a first model from seismic data expressed in one time scale and a second model from data in another time scale. A scale factor is defined by a differential equation that relates the traveltime variations of a seismic wave to the models obtained from the inversion. The joint inversion minimizes a cost function using this scale factor to evaluate the difference between synthetic data and seismic data expressed in another time scale. She has 1 patent to her name.
