<p>Apparatus and methods for controlling fluid flow within a subterranean well. A longitudinally spaced apart series of selectively set and unset inflatable packers (30,32,34) is utilized to substantially isolate desired portions (20,22,24,26) of a formation (14) intersected by a well (12). Setting and unsetting of the packers (30,32,34) may be accomplished by a variety of devices, some of which may be remotely controllable. Additionally, a series of fluid control devices (36,38,40) may be alternated with the packers (30,32,34) as part of a tubular string (28) positioned within the well (12).</p> |
