ClearFRAC CO2 Polymer-Free Fracturing Fluid

Overview Library

Designed for CO2 foam fracturing treatments

ClearFRAC CO2 polymer-free fracturing fluid was developed specifically for wells requiring the added flowback energy and hydrostatic benefits of hydraulic sandstone with liquid CO2.

The fluid was designed to be CO2-compatible, specifically addressing the technical aspects of creating a stable foam with supercritical CO2. Possessing all of the attributes normally associated with Schlumberger viscoelastic surfactant systems, ClearFRAC CO2 fluid exhibits low friction pressure and excellent proppant-carrying capacity, leaves no damage in the proppant pack, improves location logistics, and creates greater effective fracture half-lengths.

Because ClearFRAC CO2 fluids are formulated to avoid damage in the proppant pack, the fracture’s production is unimpeded. Even at low viscosity, the elastic property of the ClearFRAC CO2 surfactant makes it highly efficient at transporting proppant. The result is the ability to alter viscosity for better control of fracture geometry without compromising transportability.
