Stimulation Fluid Additive
CWF-311 Multi-Purpose Foaming Agent
CWF-311 is a blend of different, complex, alcohol-ether-sulfates that foams in fresh or hard water and
saturated brine water. CWF-311 produces large volumes of stable foam even in the presence of oil and
up to a temperature of 177ºC (350ºF).
Applications
Features, Advantages and Benefits

Foam fracturing - in nitrogen
generated foam to provide sandtransport and fluid loss control

Highly effective foaming agent producing half-life readings
of over 5 minutes in fresh water and over 3 minutes in
saturated brine

Air-foam drilling - as an aid in
removing water and drill cuttings from
the wellbore

Works in fresh or hard water, saturated brines, and in the
presence of oil contamination

Highly biodegradable

Effective temperature range up to
177ºC (350ºF)
