  • Use of swellable material in an annular seal element to prevent leakage in a subterranean well
    Patent number: 8127859
    Abstract: A method of sealing an annulus formed between a casing string and a surface in a well may include: positioning a seal element in the annulus with a swellable material of the seal element 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 may include the steps of: positioning an annular seal element in the well, wherein the element may include a swellable material; and flowing cement into at least one channel formed longitudinally through the seal element. A method of sealing an annulus between two casing strings may include: providing multiple arcuate segments that may include a swellable material; and installing the segments in the annulus, wherein each of the segments may occupy a respective circumferential portion of the annulus.
