Slim Hole Hydraulic Stage Collar

Top-Co Products' stage cementing equipment allows for 2 and 3 stage cement jobs.

This reduces breakdown of weak formations due to high hydrostatic pressure from a tall column of cement and allows for effective zonal isolation around lost circulation zones. It also assists in selectively placing cement over specific casing intervals. Stage collars are available in different casing grades, weights, and thread connections.

Making it better

Stage cementing equipment designed for effective cement placement.

The Type 680 - Hydraulic Stage Collar features two internal sleeves that shift during the stage cementing operations. The stage collar can be field set to open hydraulically at different opening pressures. This is achieved through the addition or removal of the brass shear screws from the stage cementing tool. The bottom sleeve can also be shifted open mechanically by dropping the opening dart.
