Additionally, an analysis of brittleness was proposed to identify brittle/ductile intervals and areas of potential reservoirs. The petroelastic properties were analyzed at well and seismic scales using ternary rock physics templates. These templates were built from a self-consistent micromechanical model. In addition, the analysis allows for preserving the conditions of the environment subsurface in the seismic and log information. A workflow for petroelastic lithology interpretation was coupled with a workflow of brittleness modeling. The results correlate well with conventional qualitative methodologies applied in previous studies. A brittleness analysis methodology was developed and tested to identify reservoirs associated with the Lower Cretaceous in the Stybarrow field in Australia; the results highlight the high brittleness zones attenuated by hydrocarbons (BA&gt;0.5). The proposed seismic-based methodology is an improvement to conventional analysis trends for identifying lithologies and prospective hydrocarbon zones.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen Se propone un método para identificar las propiedades litológicas del medio basado en el análisis conjunto de los parámetros de Lamé, Módulo de Young y Relación de Poisson. También se propone un análisis de fragilidad para identificar intervalos frágiles/dúctiles y áreas potenciales de yacimientos. Las propiedades petroelásticas se analizaron a escala sísmica y de pozo utilizando plantillas ternarias de física de rocas. Las plantillas ternarias se construyeron con un modelo micromecánico auto-consistente. El análisis permite preservar las condiciones del ambiente del subsuelo en la información sísmica y de registros. Se combinó un flujo de trabajo para la interpretación petroelástica de litologías con un flujo de trabajo de modelado de la fragilidad. Los resultados se correlacionan bien con las metodologías cualitativas convencionales aplicadas en estudios previos. Además desarrolló y probó una metodología de análisis de fragilidad para identificar yacimientos asociados con el Cretácico Inferior en el campo Stybarrow en Australia; los resultados resaltan las zonas de alta fragilidad atenuadas por hidrocarburos (BA&gt;0.5). La metodología propuesta basada en sísmica es una mejora a las tendencias de análisis convencionales para identificar litologías y zonas prospectivas de hidrocarburos.]]></p></abstract>
