Geomechanics field characterization of Woodford Shale and Barnett Shale with advanced logging tools and nano-indentation on drill cuttings

Abstract

The Woodford Shale and Barnett Shale have emerged as prolific gas plays in the US midcontinent. However, the intrinsically low permeability of these gas shales hinders profitable pro-duction unless horizontal well drilling and multistage hydraulic fracturing are employed. The success of these operations depends on accurate de-terminations of the anisotropic elastic and poroelastic properties of these shale formations.
