Abstract
(EN) A downhole seal (10) comprises an inflatable structure (14) which receives a volume of swellable particles (18) at a downhole location. The seal (10) is adapted to permit the swellable particles (18) to become exposed to an activator to initiate swelling of said particles (18) to inflate the inflatable structure (14).
(FR) La présente invention concerne un joint de fond de trou (10) comprenant une structure gonflable (14) qui reçoit un certain volume de particules gonflantes (18) en un emplacement de fond de trou. Le joint (10) est conçu pour permettre que les particules gonflantes (18) soient exposées à un activateur afin d’amorcer le gonflement desdites particules (18) dans le but de gonfler la structure gonflable (14).
