Abstract

Métodos y aparatos para procesar datos sísmicos adquiridos con sensores de múltiples componentes construyen un modelo preciso de velocidad de ondas S de una formación subterránea analizada mediante el uso de un planteamiento de inversión de forma de onda completa (FWI). Los datos sintéticos PS se generan mediante el uso de ecuaciones acústicas aproximadas en medios anisotrópicos con un modelo de ondas P, un modelo vigente de velocidad de ondas S y un modelo de reflectividad como entradas. El modelo vigente de velocidad de ondas S se actualiza mediante el uso de FWI para minimizar una función de costo que mitiga la discrepancia de amplitud que atenúa la disparidad de amplitud entre los datos observados PS y los datos sintéticos PS debido al uso de las ecuaciones acústicas aproximadas.
