Product advantage of hydraulic double stage collar
>>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.
