ABSTRACT:
A well test tool including a valve lowerable into a well on a flexible line and locked and sealed in a downhole landing receptacle, the valve being openable and closable to permit or prevent flow therethrough, well pressures below the test tool being sensed and recorded by a recording pressure gage both during periods of flow and during shut-in periods, the recording pressure gage being either carried by the test tool as a part thereof or being supported in the well independent of the test tool, the valve of the test tool being shiftable between open and closed positions by suitable tools lowered into the well on the flexible line, the flexible line and tools being not required in the well during either of the shut-in or flow periods, excepting only during the shifting operation, thus permitting the flexible line to be slacked during such flow or shut-in periods, or removed from the well altogether. In either case, the well test will be unaffected by movement (as by wind, wave, or similar forces) of super craft on which the flexible line reel and equipment, and personnel relating thereto, may be carried.
