Stimulation through coiled tubing
Fracture multiple zones in a single trip.
ClearFRAC polymer-free fracturing fluids were 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 fluids
Because ClearFRAC fluids are formulated to avoid damage in the proppant pack, the fracture’s production is unimpeded. Even at low viscosity, the elastic properties of ClearFRAC fluids make them highly efficient at transporting proppant. The result is the ability to alter viscosity for better control of fracture geometry without compromising transportability.
Single-trip, multizone completion system expedites integrated gravel packing operations using ClearFRAC fluids in a challenging subsea reservoir.
Historically, leakoff analyses of stimulation fluids have been performed using in-house laboratory procedures. The lack of industry standard procedures to perform leakoff and wall building coefficient analyses of stimulation fluids has introduced inconsistency in both results and reporting for many years.
Oil production from the Llanos foreland basin in Colombia is seriously affected by sand production and high water cut. Sand production has been successfully controlled with horizontal openhole gravel packs; however, early water breakthrough causing water cuts as high as 90% remained a challenge.
