Dear Mr. Corbin; STIM-LAB has completed the evaluations of the requested conductivity of the samples submitted by your firm marked 20/40 LWP 1215-2040 appearing as ceramic proppant arriving at Stim-Lab on January 12, 2016. The samples were evaluated in duplicated at 2 lb/ft2 at 250 °F and long-term for 50 hours at 2000, 4000, 6000, 8000, and 10,000 psi closure stress between Ohio Sandstone. The selected ISO 13503-2/API RP19C evaluations are also included. The procedures are outlined in the following section of this report. Figures 1 and 2 contain a summary of conductivity and permeability vs. stress. The conductivity data is presented in Tables 1 - 2. The sieve analyses of the samples are provided in Table 3. The remaining ISO 13503-2/API RP19C data is presented in Tables 4. Pictures of the representative sample are provided in Figures 3. Thank you and LWP Technologies for allowing STIM-LAB to perform this test series. If you have any questions, please do not hesitate to call. Sincerely, Kathy Abney
