Abstract
A method and a device for sealing a void incompletely filled with a castable material, in which an expandable material is placed in the void which is to be filled with the castable material, the expandable material expanding into spaces which are not filled with cast material. A method of sealing an annulus in a borehole includes the steps of: positioning an expandable material on a tubular structure; installing the tubular structure in the borehole, the annulus being formed between the tubular structure and the borehole; flowing a castable material into the annulus, the castable material partially displacing a fluid in the annulus, but leaving at least one space containing the fluid in the annulus; and expanding the expandable material into the space.
