Shale Play Characteristics and Correlation with Anisotropic Logs - A Case Study of Eagle Ford Shale in Texas

We used a model based inversion solving for Vp, Vs and Density and computed Young’s modulus and Poisson’s ratio to determine rock brittleness/ductility and total organic carbon (TOC) from rock properties. Although the lower Eagle Ford shale appears fairly consistent in its properties, we note specific variations in those rock properties that suggest they can be used to improve prospecting for hydrocarbons in the Eagle Ford shale play.
