Products Description
- Mechanical Stage collar allows cementing of casing string in two stages.
- These collar set the standard for reliability, cost effectiveness, and ease of use with outstanding built-in features and quality.
- They are the collars of choice when drilling requirements call for proven technology and low risk.
- The compact, simple design minimizes the number of moving parts and makes the tools easier to handle.
- The collar's clear opening and closing indications at the surface 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.
