	Landing Nipples and Lock Mandrels

ACTX and ACTR Landing Nipples and Lock Mandrels

ACTX and ACTR landing nipples are run into the well on completion tubing to provide a specific landing location for subsurface flow control equipment. The common internal profiles of these landing nipples make them universal. The ACTX landing nipple is used in standard weight tubing. The ACTR landing nipple is typically used with heavyweight tubing.

The completion can have as many selective nipples with the same ID in any sequence as desired on the tubing string. This versatility results in an unlimited number of positions for setting and locking subsurface flow controls. The flow control, which is attached to the required ACTX or ACTR lock mandrel, is run in the well via selective running tool on slickline.

The slickline operator using the selective running tool can set the flow control in any one of the landing nipples at the desired depth. If this location is unsatisfactory or if well conditions change, the flow control may be moved up or down the tubing string to another nipple location. These operations can be done by slickline under pressure without killing the well.

ACTXN and ACTRN No-Go Landing Nipples and Lock Mandrels

This equipment is designed for use in single nipple installations or as the bottom nipple in a series of ACTX or ACTR landing nipples. These landing nipples have same packing bore ID for a particular tubing size and weight. ACTX and ACTXN landing nipples are designed for use with standard weight tubing. ACTR and ACTRN landing nipples are designed for use with heavy weight tubing. (The N designates no-go nipples.)
