Validate sealing performance of multiple barriers

Well system integrity depends on the collective performance of the many barriers that form it. A single breach can happen anywhere, at any time, and undermine the integrity of the entire system.

 

Multi Seal evaluates the seal performance of multiple barriers, locating leaks and flowpaths throughout the well system, from the wellbore to the outer annuli.

 

Delivered by our True Integrity system with Chorus (acoustic) technology, Multi Seal Integrity provides a clear diagnosis of leaks and rogue flowpaths so the right corrective action can be taken.

 

Multi Seal Integrity is used in a targeted fashion to investigate a known integrity breach anywhere in the well system. Barriers can also be validated proactively to confirm integrity. Either way, Multi Seal provides the insights needed to restore or maintain a secure well.

Challenges

  • Evaluate integrity and sealing performance of multiple barriers
  • Sustained pressure in one or more cemented annuli (SAP)
  • Abnormal production or injection performance
  • Barrier leaks and unwanted flowpaths throughout the well system
  • Micro-leaks throughout the well system
  • Completion component failures

Benefits

  • Comprehensive diagnosis of leaks and unwanted flowpaths throughout the well system
  • Identify true source of SAP in any annulus
  • Locate micro-leaks and flowpaths
  • Locate leaks and flowpaths to mitigate integrity risk and ensure regulatory compliance
  • Rapid deployment through-tubing minimises disruption and cost
  • Better remediation decisions, precisely targeted

Indicative logplot for Multi Seal Integrity Oil producer was never perforated due to an integrity issue in the A-annulus. Multi Seal Integrity was executed under A-annulus pumping conditions to determine leak points across multiple barriers. Log plot shows collars of 9⅝ casing is leaking at 35.5m, 85.0m, 122.2m, 196.3m, 419.0m, 443.5m, 628.9m, 665.8m and 789.7m.
