Abstract
A method of deploying an expandable composition in a cement top job in a well system includes identifying evidence of actual or potential gas migration within an annulus cement of the well system. Once the evidence of gas migration is identified, a first component and a second component are mixed in a mixer to form the expandable composition and the expandable composition is pumped from the mixer through a conduit to a top of cement of the annulus cement. The expandable composition expands to form an expanded composition that seals the annulus above the top of cement of the annulus cement. Cement can be added onto the expanded composition.
