The X Running Tool is designed for the deployment and setting of subsurface flow control devices with X® and XN® lock mandrels. These devices are intended to land in corresponding selective or no-go landing nipples within the well bore. The X Running Tool offers the flexibility to operate in either selective or non-selective modes. In selective mode, operators can run devices through landing nipples of the same size and type. The operator can then perform manipulations at the desired location nipple before setting the device. Alternatively, in non-selective mode, the lock mandrel automatically locates the first corresponding nipple.
