Overview

Analysis reveals that a Thru-Tubing system improves well abandonment efficiency, reducing costs and operational risks in South Texas.

Key Points

  • Permanent well abandonment reduced costs significantly using a Thru-Tubing system with flow diverters.
  • The Thru-Tubing method established a cement plug that complies with regulations in a case study in South Texas.
  • Intervention utilized innovative bottomhole assembly tools, optimizing efficiency without a conventional rig.
  • Reduction in operational risks and environmental impact highlights the advantages of this advanced abandonment technique.
