ScaleFRAC Scale Inhibitor

One-Step Scale Inhibitor and Fracture Treatment

The ScaleFRAC system protects wellbores and propped fractures from scale damage and related production declines. This system overcomes scale inhibitor placement problems by integrating scale inhibitor and fracture treatments into one step, guaranteeing that the entire well is treated with scale inhibitor.

High-efficiency scale inhibitor is pumped into the matrix surrounding the fracture face during leakoff. It adsorbs to the matrix during pumping until the fracture begins to cut water. As water passes through the inhibitor-adsorbed zone, it dissolves sufficient inhibitor to prevent scale deposition. Water production is balanced by inhibitor contact to maximize treatment life.

Reduced total wellsite delivery cost

A field trial conducted in the Permian basin showed the cost of the ScaleFRAC system to be significantly less than conventional methods. This system provided the lowest water treatment cost on the basis of cost per barrels of water treated with inhibitor. Overall, this system is 30% less costly than conventional processes.
