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.
