SEAL-BORE SUB

Description
The Seal-Bore sub is a simple short tubing sub with integral GO/NOGO made from the same casing material and the same connection with elastomer Sealing pack inside for the polished stinger used on the inner string.

This sub can be placed at the bottom of the screen assembly. This ensures treatment fluids are pumped all the way to the end or bottom of the production screens to promote complete screen covering with gravel.

The stinger is a simple polished tubing section with an integral NO-GO to provide wash-pipe isolation to enable wash-down and protect screens from mud solids plugging.

The standard length can be adapted to suit the application with shifting tool
interface and based on expected tubing movement etc.
