Product Description
Mechanical Stage collar
Mechanical Stage collar allows cementing of casing string in two stages. These collar set the standard for reliability, and ease to use with outstanding built-in features .Low risk, compact, simple design to minimizes moving parts and makes the tools easier to handle.
The collar's clear opening and closing indications at the surface to accommodate the hydraulic conditions of the well for safer, more efficient operations. The internal sleeves increase reliability and prevent premature opening from formation restrictions on applied pressures.
It reduces total pumping pressure in long casing strings.
Hydraulic stage collar
Hydraulic stage collar meets the challenges of cementing holes at any angle with the hydraulically opened port system. Stage collar is designed specifically for horizontal completion and used for Primary cementing in deep vertical or high deviated horizontal-well conditions.
It reduces total hydrostatic pressure on 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.
Features:
1. Available to mechanical stage and Hydraulic stage type.
2. makes the tools easier to handle.
3. compact, with outstanding built-in features.
