The Surelocate feature of Kobold’s Sandhawk bottomhole assembly, assures positive sleeve locate at every frac stage for maximum speed and efficiency.

Kobold’s Surefrac service provides operators with a downhole system to fracture a well formation in an efficient and cost-effective manner. Faster sleeve locate and transition time between stages help reduce pumping, coil tubing and other associated operational costs. Kobold has engineered these downhole tools to ensure reliable results, while maximizing productivity over fracturing multiple stages.

The Surefrac service, with its Sandhawk bottomhole assembly, deliver unlimited stage sequencing within a frac program. The Surelocate feature reliably locates and locks only into our Sandport frac sleeve profile, providing operators with additional confidence at every stage.

These unique Kobold differentiators, enable the ability to always locate Sandport sleeves, open and/or close with confirmation, and quickly transition between stages.
