The PARVEEN X and R Running Tools are used to set model ‘X’, ‘XN’, ‘R’, ‘RN’ and ‘RQ’ Lock Mandrels in their respective landing nipples. The X and R Running Tool can be set up to run either in selective or non-selective mode. In selective mode the lock mandrel can be run through several landing nipples of the same size and type before selecting the desired nipple to set the lock mandrel. In non-selective mode, the lock mandrel will locate the first corresponding nipple.
