PARVEEN X and R Landing Nipples and Lock Mandrels
PARVEEN X and R landing nipples are run into the well on the completion tubing to provide a specific landing location for subsurface flow control equipment. The common internal profiles of these landing nipples make them universal. PARVEEN X landing nipple is used in standard weight tubing. PARVEEN R 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 PARVEEN X or R lock mandrel, is run in the well via the 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.
PARVEEN XN and RN 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 PARVEEN X or R landing nipples. These landing nipples have the same packing bore ID for a particular tubing size and weight. PARVEEN X and XN landing nipples are designed for use with standard weight tubing. PARVEEN R and RN landing nipples are designed for use with heavy weight tubing. (The N designates no-go nipples.)
