R Lock

R Lock

Purpose

To locate and lock a variety of subsurface controls in the desired corresponding nipple profiles.

Description

The “R” lock mandrels with the flow control components are designed for the “R” seating nipples installed in heavy weight tubing. These lock mandrels similar in design are selective, this is made possible by their running tools.

The lock mandrels maybe installed in any one of multiple seating nipples installed in the tubing string of comparable size. Once the desired nipple has been located in the tubing string these mandrels are mechanically locked. This is done by driving the expander sleeve behind the keys, holding the mandrel in a locked position.

Operation

The “R” lock mandrels are ran selective, or can be ran in the non selective position when setting in the upper “R” profile in the tubing completion string. Both the running positions are built into the running tool which has a set of locating dogs to selectively run and set the lock mandrels in the lower nipples in the string.

The running tool is changed to a non selective position once the desired selective nipple has been located. This is done by lowering the running tool with the lock mandrel through the nipple profile and then pulling back up through. The “R” running tool procedures are explained in the “X” running tool operation in the running tools section.
