Abstract
A replaceable gas lift valve system. In this system, the device is inserted into the production tubing (or gas producing zone) at a desired level. This allows gas to be pumped down the space between the casing and production tubing (or flowed from the zone). Although the tool is placed in the production tubing, space is provided to allow almost normal production through the tool. Once in place, the device has a metering valve that allows the appropriate amount of gas of other fluid to enter the production tubing to provide lift for the oil. If the device fails, it can be quickly extracted and a replacement device quickly installed. Once installed, the replacement device allows resumed production. The recovered device can be dismantled, repaired and staged for another quick replacement where needed.
