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.

Abstract: A visual inspection system intended for inspection of the difficult to reach lateral wellhead ports and annulus is provided. The inspection of the annular ports is carried out prior to running a simplified annulus intervention system. The imaging assembly of the visual inspection system of the present invention can be manoeuvred to view and capture images of remote, inaccessible, difficult to reach locations in the lateral access port and the adjacent annular region, prior to running of annulus intervention system, thus enhancing the success rate of carrying out annulus interventions and increasing safety by increasing the efficiency of well intervention operations and reducing the risk of unintended incidents.
