Abstract
System and methods for efficient sealing within an annulus outside the casing of a subterranean wellbore using annulus intervention insertion system are disclosed. Some examples describe a system that includes a magnetorheological cementitious material and a magnetic field induced by electromagnet provided inside the wellbore. Efficient cementing is achieved by holding the magnetorheological cementitious material to in the desired position by the magnetic forces of the electromagnet; and allowing the magnetorheological cementitious material to harden and set in the annulus.
