SF Cementor D Stage Collar

Cementing Tool for Monobore Completions

The Packers Plus SF Cementor® D stage collar is designed to be hydraulically opened and closed using an actuation ball or specialized wiper plug. This design enables the stage collar to be opened and closed without any mechanical movement at surface.

Cemented-back monobore well construction involves cementing the vertical and build sections of a well from the heel back to surface with a stage tool, rather than running intermediate casing. This technique reduces total wellbore construction costs, and eliminates trips needed to remove the running string and install the fracture string. The stage tool is run as part of the system liner in open hole, multi-stage completions.

The SF Cementor D stage collar offers many features and benefits

Reduced wellbore construction costs by elimination of intermediate casing

Lower risk of lost stages using integrated secondary closure sleeve with no loss of inside diameter

Reduces time and cost of clean-out operations

SF Cementor D Stage Collar

The StackFRAC® (SF) Cementor® D stage collar is a hydraulically opened stage cementing tool that is closed using an actuation ball or specialized wiper plug. It is used to cement the section above Packers Plus open hole multi-stage systems. The SF Cementor D stage collar design allows it to be opened and closed without any mechanical movement at surface.

Debris Sub

The Debris Sub is used in conjunction with cementing stage tools such as the SF Cementor stage collar. The main functions of the Debris Sub are to provide a barrier to cement stringers or debris during cementing, and to act as a platform for clean-up operations. The Debris Sub accepts a standard Packers Plus actuation ball, and can be fully milled out to regain communication with the tool string.

The Packers Plus SF Cementor D stage collar helps operators improve operational efficiencies of open hole, cemented-back completions and can be combined with a liner hanger to cement-back zones above the target depth
