  1. EPOXY RESIN DEMONSTRATES INTEGRITY & FINANCIAL ADVANTAGES IN O&G WELL ABANDONMENTS Tyler James: IOGCC 2018

  2. CSI Technologies, LLC 1. Research Quality Lab 2. Team of Well Integrity Specialists

  3. The Number of Wells Needing to be Plugged and Abandoned Why is it a problem: Cost Why plug and abandon: Risk

  4. The cost to restore zonal isolation for uneconomic wells Reduce Cost The Solution:

  5. Evaluate Innovate Re-regulate

  6. Evaluate Evaluate post P&A well integrity Evaluate P&A cost

  7. SCP Occurrence 100 87% 90 80 After Stimulation 70 Before Stimulation % of Wells 60 50 40 30 18% 20 10 0 PRE REGULATION POST REGULATION CHANGE CHANGE

  9. B Annulus

  10. Evaluate Evaluate post P&A well integrity  Moving in the correct direction Evaluate P&A cost  Identify largest impact areas

  11. Innovate Alternative methods to place barrier material Alternative barrier materials

  12. Alternative barrier materials Mechanical Failures Micro-annulus Dehydration Chemical Attack Contamination

  18. Innovate Alternative methods to place barrier material • Limited Alternative barrier materials • Developed

  19. Re-regulate Regulations are currently limited to cement

  20. Case Study  13,000 psi wellhead pressure  BOP use not feasible  Obstruction in the flow path  Needed to isolate formation at 30,000 ft MD 23 10/4/2018

  21. The Operation: Abandon  Pumped 37 bbls of ControlSEAL  Injected 10 bbls of resin into formation 24 10/4/2018

  22. The Success  Well killed and pressure isolated  No Health, Safety, Environmental incidents  Significant financial benefits for operator – Highest risk well  First resin-only approved lower abandonment 25 10/4/2018

  23. Summary The Problem: – The cost to restore zonal isolation for uneconomic wells The Solution: – Lower cost  Evaluate  Innovate  Re-regulate Epoxy Resin is a alternative barrier material that has showed integrity and finical advantages compared to cement
