Revolutionizing Wellbore Integrity Solutions
Since 2016, Radial Casing Solutions has been developing a revolutionary and patented casing expansion tool we call REED – Radial Elastomer Expansion Device. By expanding the casing under forces controlled from surface, REED uses the casing itself to resolve wellbore integrity issues in the casing annulus without compromising casing integrity
For the first time, operators can materially reduce the cross-sectional area and change the behavior and characteristics of the casing annulus without perforating and injecting sealants. This retains casing integrity while resolving complex wellbore integrity issues such as Surface Casing Vent Flows (SCVF) or interzonal communication of liquids or gases.
For vent flows, Radial’s REED can be considered a “mechanical cement squeeze” whereby the annular cement is compressed and reformed, thereby sealing micro-annular leaks and “worm holes” at a fraction of the cost of conventional methods.
REED can expand a wide range of common casing sizes, grades, and weights, from 4-1/2” to 9-5/8” and can easily be adapted or custom made the most challenging applications.
Through extensive shop testing followed by successful field deployment, the REED technology has also been adapted for use as a liner top steel-on-steel seal/barrier for SAGD operations.
Since 2020, REED has completed numerous jobs with consistent success. Radial has demonstrated reliability without any issues related to tool performance or retrieval of the tool post well expansion.
