Selectively set and unset packers |
摘要 |
Apparatus and corresponding methods are disclosed for controlling fluid flow within a subterranean well. In a described embodiment, a longitudinally spaced apart series of selectively set and unset inflatable packers is utilized to substantially isolate desired portions of a formation intersected by a well. Setting and unsetting of the packers may be accomplished by a variety of devices, some of which may be remotely controllable. Additionally, a series of fluid control devices may be alternated with the packers as part of a tubular string positioned within the well.
