Normalized gamma ray and density porosity values are provided for six sand zones in a well containing a sand-shale lamination sequence. The sand layers may or may not contain dispersed clays. Do the following. a. Plot the normalized gamma ray and density porosity values for each sand zone on the Thomas-Stieber plot below b. Determine the sand porosity in each zone c. Determine the net/gross percentage for each sand zone d. Which zones contain gas?
