New cement reacts to microleaks in the cement sheath and responds immediately to seal them permanently.

Schlumberger announced today the availability of its FUTUR* active set-cement technology that automatically seals microleaks in a cement sheath.

Pumped and placed as part of any primary cementing operation, the active components of the FUTUR cement system remain dormant until exposed to hydrocarbons, such as those seeping through cracks or microannulae in the cement sheath. Upon activation by contact with hydrocarbons, the FUTUR cement sheath will self-repair without intervention. This prevents the annular migration of fluids behind the casing between zones or the sustained casing pressure (SCP) at surface.
