Schlumberger has developed an isolation solution based on a responsive cement blend with intrinsic self-healing properties. FUTUR active-set cement technology is automatically activated upon contact with hydrocarbons, improving long-term zonal isolation and protecting against hydrocarbon leaks and SCP at the wellhead. Pumped and placed as part of any primary cementing operation, FUTUR creates a cement sheath that provides an additional level of protection above the reservoir, reacting whenever the cement sheath is damaged during the long-term productive life of the well.
