Prevention, actuation and control of deployment of memory-shape polymer foam-based expandables |
| abstract |
Actuation and control of the deployment of a polymeric memory-shape material on a wellbore device on a downhole tool may be accomplished by treating a compacted or compressed polymeric memory-shape material with an optional deployment fluid to lower its Tg and/or decrease its rigidity, thereby softening the polymeric shape-memory material at a given temperature and triggering its expansion or recovery at a lower temperature. Recovering the polymeric shape-memory material may occur by its being exposed to a particular temperature range. Alternatively, the deployment of the compacted or com pressed polymeric memory-shape material may be prevented or inhibited by shielding the material with an environment of a fluid that does not substantially lower its Tg, decrease its rigidity or both, and then subsequently contacting the material with a deployment fluid. The deployment fluid may be removed during the method. |
