Sweet spot identification for source rocks involve detection of organic rich, high porous facies combined with brittleness, which is prone for hydraulic fracturing for optimized production. The current study focuses on identifying the best shale out of three shale plays (Barnett, Marcellus and Eagle Ford). The aim of the study is to understand how the source rock properties such as organic richness and porosity will affect elastic and geomechanical properties. We found from the study that Barnett shale is the best shale out of the three shale plays, because this play not only has better organic richness and porosity development, it also has better brittle nature and these properties can be characterized from seismic data.
