• Schlumberger published the fits to many of their rock dielectric measurements in a 1990 Geophysics paper

• Below is a summary of the fitted parameter representing the high frequency limit for the sandstone data

• Some scatter would be expected from measurement error and uncertainty about porosity

• While none of the results are outside the "absolute or Wiener bounds", the extent of the scatter indicates potential serious problems with this data
