CL-FREE™
Low Salinity Water-Based
Description
CL-Free™ meets challenging drilling targets with minimal environmental impact. CL-Free™ should be considered in formations such as micro fractured shale, formations with interbedded dispersive clays, or where shales and reservoirs are at one interval.
- Application
CL-Free meets challenging drilling targets with minimal environmental impact. CL-Free should be considered in formations such as micro fractured shale, chalk or formations with interbedded dispersive clays, or where shales and reservoirs are at one interval.
- Benefits
CL-FREE avoids chloride and high-salinity WBMs while improving solids removal efficiency. The CL-FREE system results in reduced bit-balling, dilution rates, production consumption, overall operating cost, and elapsed drilling time. Dispersion tests indicated that the inhibition of CL-FREE system is comparable to that of oil or synthetic base systems.
