For SCVF, 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 perform a mechanical cement squeeze by expanding the casing and compressing the cement in the annulus, thus re-sealing the interval and closing micro-annular passages or cement wormholes.

The REED system is less invasive than perforating. Testing has proven that casing cement has plasticity, and the REED system compresses the cement. The cement used in wellbores is not like construction concrete, which is a mixture of cement and aggregate. Wellbore cement is uniform and does not have any internal shear points created by mixing cement with sand or gravel.

What REED can achieve:

• Three sets of nine expansions – 27 expansions total – have been conducted at three different intervals in nine hours of rig operating time
• Compelling results greater relative to stand-alone cement squeeze success results of approximately 30% (Source: NRCAN)
