SX and SR Landing Nipples

SX and SR landing nipples are run into the well on the completion tubing to provide a specific landing location for subsurface flow control equipment. These landing nipples feature common internal profiles making them universal. The SX landing nipple is used in standard weight tubing. The SR landing nipple is typically used with heavyweight tubing.

The completion can include as many selective nipples with the same ID in any sequence asdesired on the tubing string. This versatility results in an unlimited number of positions for setting and locking subsurface flow controls.

SXN and SRN Landing Nipples

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


Applications of landing nipples

  • Gauge hangers for bottom hole pressure/temperature surveys
  • Positive locator for straddle systems
  • Plugging under pressure
  • Almost unlimited locations for setting and locking subsurface flow controls



Benefits of landing nipples

  • Versatility helps reduce completion and production maintenance costs
  • Simple operation
  • Multiple options when running, setting, or retrieving subsurface flow controls
