However, the application of FWI on land datasets is a much more challenging process than its application on marine datasets. This paper suggests a step-by-step guide for the 2D acoustic FWI on a synthetic dataset, in particular, in which we used the SEAM Phase II-Foothills dataset that exhibits many of the characteristics of real land data. The methodology includes tools for the processing of seismic data based on the features of acquisition geometry, source estimation, first arrival tomography, plus the software strategies to meet the requirements of the FWI (memory and computation requirements). The document also includes a discussion of the results of velocity models obtained for a low-resolution Dip 2D line of the SEAM data, using a workstation with low-to-intermediate hardware requirements.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[RESUMEN La inversión de onda completa (FWI, por sus siglas en inglés) se ha aplicado con éxito en la exploración sísmica de hidrocarburos porque permite encontrar modelos de velocidad y densidad de alta resolución. Sin embargo, la aplicación de FWI en conjuntos de datos terrestres es más difícil que su aplicación en conjuntos de datos marinos. Este artículo presenta una metodología para aplicar FWI acústico 2D en el conjunto de datos SEAM Phase II-Foothills que se asemeja a los datos reales de la tierra. La metodología incluye las herramientas para el procesamiento de datos sísmicos que consideran las características de las geometrías de adquisición, la estimación de la fuente, la tomografía de primera llegada; y los desarrollos software para satisfacer los requisitos del FWI (requisitos de memoria y cómputo). El documento también incluye una discusión sobre los resultados de los modelos de velocidad obtenidos para una línea de baja resolución Dip 2D de los datos SEAM, utilizando una estación de trabajo con requerimientos de hardware de bajo a intermedio.]]></p></abstract>
