The apparatus comprises an activation-device seat, one or more bypass ports, a J-slot with an indexing pin and a spring. When an activation device, for example a ball, lands in the activation-device seat, fluid communication through the tubular body is blocked, allowing pressurization. During pressurization, the activation-device seat moves downward, causing the spring to compress and the indexing pin in the J-slot to move to the bottom position. Upon depressurization after the test, the activation-device seat moves upward, causing to spring to decompress and the indexing pin the J-slot to move to the top position. Upward movement of the activation-device seat unblocks the bypass ports, thereby reestablishing fluid communication through the tubular body. The tubular body may be drillpipe, casing or coiled tubing that is installed in the borehole of a subterranean well. | 06-28-2012 |
