Title: Luis D'Afonseca: Seismic Imaging Innovation

Introduction

Luis D'Afonseca is an inventor associated with Rio de Janeiro, Brazil, and Cgg Services Sas. His patent work addresses a challenge in seismic imaging: identifying data that may cause cycle-skipping during full waveform inversion.

Latest Patents

The provided information lists one patent for D'Afonseca: “Device and Method for Mitigating Cycle-Skipping in Full Waveform Inversion.” The invention describes a computing device, computer instructions, and a method for identifying seismic traces prone to cycle-skipping. It receives recorded seismic data from sensors over a subsurface of interest, selects a model of that subsurface, and calculates estimated seismic data using the model and recorded measurements. It then selects a probabilistic measure, including at least one statistical function, to characterize the relationship between the recorded and estimated data. This approach is intended to help identify traces that could affect the inversion process.
