Abstract
A method of sealing an annulus formed between a casing string and a surface in a well includes: positioning a seal element in the annulus, a swellable material of the seal element being positioned between the casing string and the surface; and flowing cement through a channel formed between the swellable material and the casing string. A method of sealing in a well includes the steps of: positioning an annular seal element comprising a swellable material in the well; and flowing cement into at least one channel formed longitudinally through the seal element. A method of sealing an annulus between two casing strings includes: providing multiple arcuate segments, each of the segments comprising a swellable material; and installing the segments in the annulus, each of the segments thereby occupying a respective circumferential portion of the annulus.
