Losseal Microfracture

Seals fractures fast to reduce NPT, lower costs, and achieve required top of cement

Losseal Microfracture™ lost circulation control treatment blends specially engineered fibers with optimally sized solid bridging materials. This combination enhances the solid volume fraction (SVF) of carrier fluids—such as muds, spacers, or cements. It is effective in both water- and oil-based systems. By using the Losseal Microfracture treatment, operators can regain or maintain circulation, run casing without fluid losses, and achieve the required top of cement (TOC) —all while minimizing NPT and operational costs.

• Drilling, casing, and cementing operations with fluid losses less than 40 bbl/h
• Microfractured formations with fracture widths less than 1 mm
• Weak zones and depleted formations

• Mitigates risk of fluid losses
• Cures losses without needing to set cement plugs
• Eliminates the need to pull out of hole because it can be pumped through small bit nozzles
• Helps regain circulation quickly
• Enables achieving required TOC
• Reduces time-consuming and costly remedial operations
