System and method to seal using a swellable material

A sealing system for use in a well, comprising:

• a swellable material disposed on a conveyance device;
• wherein the swellable material swells when in contact with a triggering fluid to contact a wellbore wall or a casing to form a first annular barrier in the well;
• and
• wherein cement is disposed in the well to contact the wellbore wall or the casing to form a second annular barrier adjacent to the first annular barrier.

A method for sealing for use in a wellbore, comprising:

• deploying a swellable material on a conveyance device in the wellbore;
• exposing the swellable material to a triggering fluid to cause the swelling of the swellable material;
• monitoring the swelling process of the swellable material, comprising monitoring a temperature of the swellable material;
• and
• using the results of the monitoring of the temperature to determine whether swelling of the swellable material has been initiated.
