Latching Seal Assembly

Coiled tubing latching to velocity string
Description

Applications

 

  • Isolation of a sliding sleeve or production tubing leak.
  • A velocity string to enhance production.
  • Dual-zone production by utilizing a sliding sleeve.
  • Coiled tubing drop-off to unload liquid below an existing completion.

Features

 

  • Lip-Seal Packing Unit provides a robust seal between the coiled tubing and seating nipple.
  • Coiled tubing is anchored to prevent unlatching of the seal assembly due to pressure differentials.
  • Seal assembly may be customized to latch and seal in a wide variety of well configurations.
  • Coiled tubing may be dropped off and hung below the seal assembly, extended from the seal assembly to surface or both.
  • Seals and metallic components may be customized to suit a wide range of well environments.

The Evolution Latching Seal Assembly provides a means to latch and seal a coiled tubing velocity string inside conventional production tubing. The seal assembly features a rugged Lip-Seal Packing Unit and a shear style Latching Collet to anchor and isolate the coiled tubing. The Latching Seal Assembly is deployed into existing production tubing on coiled tubing and latched into a downhole flow control seating nipple. Once latched, the seal assembly and tailpipe may be dropped off and used as a downhole velocity string or tied back to surface as a full-length velocity string. When coiled tubing is extended to surface, hang-off is achieved with a Select threaded or flanged hanger.
