Velocity-Porosity-Mineralogy Model for Unconventional Shale and Its Applications to Digital Rock Physics
By examining wireline data from Woodford and Wolfcamp gas shale, we find that the primary controls on the elastic-wave velocity are the total porosity, kerogen content, and mineralogy.At a dali ballast fixed porosity, both Vp and Vs strongly depend on the clay content, as well as on the kerogen content.Both velocities are also strong functions of t
