Horizontal Drilling in Kansas Conclusions

• Currently a Mixed Bag of Successes and Failures
• Most Horizontal Candidates not Properly Screened
  and Completed
• Many Good Candidates not yet Tested
• Thin Beds in Lansing-Kansas City
• EOR in Multiple Reservoirs
• SAG-D Thermal in Cherokee Sands of SE Kansas
• Still not Far Up the Learning Curve
