CL-FREE™

Low Salinity Water-Based

Description

The AphronICS is patent-proven engineered drilling fluid system that controls pressure (losses) in depleted, high-porosity, fractured formations while stabilizing pressured shales.

AphronICS replaces UBD, MBD, LCM, drill multiple pressure zone, and depleted formations to successfully complete many reservoirs that previously would have been candidates only for multi intervals, under-balanced drilling or even abandoned reserves due to drilling difficulties.

This technology reduces your risks of invasion, lost circulation, differential sticking and formation damage, while increasing production levels.

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.

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.

The low salinity system designed to meet difficult drilling targets with minimal environmental impact. Formations such as micro fractured shale, chalk or formations with interbedded dispersive clays and sands are the applications where a CL-FREE system should be considered. Formulations are treatment are available on the system brochure.
