1. Versaprop Increased Value Increased Strength Increased Profitability

2. Versaprop Higher Conductivity per $ –25% to 37% more conductivity Greater Strength –Only 1.4% Crush at 7,500 psi Increased Productivity –More conductivity means increased effective fracture half-lengths

5. Versaprop provides conductivity within 10% of premium light-weight ceramics at lower costs

6. Versaprop provides conductivity above that of intermediate ceramics as lower costs

9. 30/50 API ceramic proppants range in MPD from 0.43 mm to 0.512 mm

10. 20/40 API ceramic proppants range in MPD from 0.635 mm to 0.723 mm

11. 16/30 API ceramic proppants range in MPD from 0.928 mm to 0.974 mm

12. While Versaprop is not a 20/40 API proppant, It’s MPD is very similar to one

13. Typical

17. Versaprop A medium density (3.2 g/cc) ceramic proppant which through grain size and strength provides increased conductivity (25% - 37%) at competitive prices to light- weight economic ceramic proppants.

18. Versaprop A proppant for the widest range of application High conductivity at low stresses High conductivity and strength at high stresses
