Title: Innovations of Nicolas Chazalnoel

Introduction

Nicolas Chazalnoel is an accomplished inventor based in Houston, TX (US). He has made significant contributions to the field of geophysics, particularly in seismic data analysis. His innovative approach has led to the development of advanced methods for subsurface formation evaluation.

Latest Patents

Nicolas holds a patent for "Reflection full waveform inversion methods with density and velocity models updated separately." This method focuses on updating a density model and a velocity model of a surveyed subsurface formation independently. It involves generating a model-based dataset that corresponds to the seismic dataset using both models. The objective function measures the difference between the seismic dataset and the model-based dataset. A high-wavenumber component of the objective function's gradient is utilized to update the density model. Subsequently, the model-based dataset is regenerated to calculate an updated objective function, which is then used to update the velocity model. Ultimately, a structural image of the subsurface formation is generated using the updated velocity model.
