Abstract
Certain aspects are directed to a testable isolation packer (10) that sets and provides the ability to test upper and lower packer elements (12, 14). In one aspect, the testable isolation packer includes at least two packer elements, a packer element setting system, a bypass system (62), and a testing subassembly (68). The testing subassembly generally includes a moveable element (22) with an outer port (74) and a sealing element (80), an inner mandrel (78) with an inner port (76), and a shear mechanism (36, 38, 46, 52, 70) to cause travel of the moveable element close the bypass system and to open the testing subassembly.
