Abstract
An apparatus for isolating a first zone ( 12) from a second zone (14) in a subterranean wellbore (10). The apparatus includes an outer tubular (102) and an inner tubular (124) disposed within the outer tubular forming an annular flow path (174) therebetween that is in fluid communication with the first zone. The inner tubular defines a central flow path (172) that is in fluid communication with the second zone. A sleeve ( 176) having at least one seal ( 178) is positioned in the annular flow path and is axially movable relative to the inner and outer tubulars between a closed position wherein the seal engages the inner tubular and an open position wherein the seal engages the outer tubular. A mandrel ( 150) is slidably disposed within the inner tubular and is coupled to the sleeve. The mandrel is operable to shift the sleeve between the open position and the closed position responsive to changes in pressure within the central flow path. FIGURE 3B
