Products Description

Hydraulic stage collar meets the challenges of cementing holes at any angle with a hydraulically opened port system.
Stage collar designed specifically for horizontal completion.
It is specifically used for Primary cementing in deep vertical or high deviated horizontal-well conditions.
It reduces total hydrostatic pressureon weak formations to prevent lost circulation during cementing.
Clear surface indications of opening and closing pressures provide safer and more efficient operations.
The opening pressure of the stage collar can be adjusted at rig site to meet well requirements, providing operational flexibility.
