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

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

Evaluate Innovate Re-regulate

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

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

Re-regulate Regulations are currently limited to cement

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

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

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

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
