Abstract
An indexing tool is incorporated into a tubular string. The indexing tool is intended to function as a variable travel stop so that on initial landing other tools associated with the string will not extend to an operating position for tools that would otherwise operate on contact with relative movement. The indexing device can prevent a shifting device from engaging a valve operator when the index device initially lands on a support either during normal operation or in an emergency such as when shear rams have cut the string to allow it to fall so that a blowout preventer can be operated to engage opposed rams. In such an emergency the barrier valve operator will not be actuated and the string is later fished with the barrier valve closed. A pickup and set down force then allows the barrier valve to open when desired.
