Inspection method for cement assessment behind multiple steel barrier in P&A wells (TC13)

2021 Success Stories - 29 Oct

Pain Points:

Conventional logging technology is inadequate for assessing cement quality behind multiple steel barriers in Plug and Abandonment (P&A) operations. It fails to log through multiple layers of metal, making it impossible to accurately evaluate the condition of the cement. This limitation necessitates the development of advanced inspection methods to ensure reliable cement assessment.

Requirements:

A non-intrusive, efficient inspection technique is needed to accurately evaluate cement integrity behind multiple steel layers during online P&A without tubing removal, reducing costs and providing a clear zone-isolation log and map.

Winner:

Probe Technology Services Inc.'s "Multi-String Isolation Logging (MSILM)" uses acoustic waveform analysis and proprietary algorithms to assess cement integrity behind multiple strings without tubing removal, delivering a clear zone-isolation log and map.
