Stage Tools

Cementing stage collars for monobore completions

Cemented-back monobore well construction reduces total wellbore costs by 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 also eliminates trips required in traditional operations of removing the running string and installing the fracture string.

Packers Plus offers a range of field-proven stage tools that are specially designed to reduce operational risk and improve efficiency.


Packers Plus stage tools offer many features and benefits

Reduced wellbore construction costs by eliminating intermediate casing

SF Cementor® and SF Cementor D stage tools lower risk of lost stages with integrated secondary closure sleeve that provides no loss of diameter

Degradable stage tool options eliminate time and cost of clean-out operations

SF Cementor Stage Collar

The SF Cementor stage collar is a hydraulically opened, mechanically closed stage cementing tool. The SF Cementor is closed without the use of a wiper plug or dart, which eliminates the need for a cement head and reduces post-cement cleanout operations, debris issues and associated costs.

SF Cementor D Stage Collar

The SF Cementor D stage collar is a hydraulically opened stage cementing tool that is closed using an actuation ball or specialized wiper plug. A degradable version is available that includes a degradable wiper plug and landing seat to eliminate millout operations.


SF Stage Collar

The SF Stage Collar is a hydraulically opened stage cementing tool that is closed using an actuation ball or specialized wiper plug. This simplified version of the SF Cementor D stage collar does not include a secondary closure sleeve, but is available in degradable version to eliminate millout.

Debris Sub

The Debris Sub is used in conjunction with cementing stage tools to provide a barrier to cement stringers or debris during cementing, and to act as a platform for clean-up operations. The Debris Sub is easily milled out to regain communication with the tool string. A degradable version is available to eliminate millout operations.
