Case Study

23 10/4/2018

  • 13,000 psi wellhead

pressure

  • BOP use not feasible
  • Obstruction in the flow

path

  • Needed to isolate

formation at 30,000 ft MD

slide-24
SLIDE 24

The Operation: Abandon

24 10/4/2018

  • Pumped 37 bbls of ControlSEAL
  • Injected 10 bbls of resin into formation
slide-25
SLIDE 25

The Success

25 10/4/2018

  • Well killed and pressure isolated
  • No Health, Safety, Environmental incidents
  • Significant financial benefits for operator

– Highest risk well

  • First resin-only approved lower abandonment

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
