Abstract

A travel joint comprises an outer housing, an inner mandrel, a first release device positioned between the outer housing and the inner mandrel, and a second release device positioned between the outer housing and the inner mandrel. The first release device is configured to actuate from the locked position to the unlocked position in response to a fluid pressure supplied to the first release device. The second release device is configured to selectively prevent and allow relative axial movement between the outer housing and the inner mandrel in response to an axial force applied to at least one of the outer housing or the inner mandrel, and the first release device is configured to prevent the application of the axial force to actuate the second release device in the locked position and allow the axial force to actuate the second release device in the unlocked position.
