Shale is highly heterogeneous in nature, leading to challenges in shale reservoir exploration and production. Geoscientists have been searching for solutions that can determine and qualify the “sweet spots” where the production and recovery rate are highest in the shale formation.
Seismic data carries important information about subsurface geology and rock properties.  When properly processed, imaged and analyzed, the seismic data becomes a vital source of information for the characterization and assessment of shale heterogeneity, in situ stress, TOC and brittle/ductile quality. However, the use of seismic data is often limited by the seismic resolution.
As increasing amounts of well data become available, incorporating seismic with well data provides a mechanism for accurately estimating rock properties that delineate the reservoir quality.  In this presentation we propose a workflow using prestack inversion with stochastic refinement to study shale property distribution in the Eagle Ford formation.
