Abstract

En teknikk er tilveiebrakt for å isolere regioner av en brønnboring. Teknikken anvender en svellbar materialpakning som omfatter et lag av svellbart materiale som er anordnet omkring et rørformet element i en komplettering. Når laget utsettes for en substans som forårsaker svelling av det svellbare materiale, ekspanderer laget mellom røret og en omgivende vegg for å isolere en region av brønnboringens ringrom.
