A B DEFOAMER additive is a liquid defoaming agent formulated with higher alcohols to control foaming in all
water-base drilling fluids containing freshwater, brackish water, seawater, saltwater, and saturated saltwater, as well
as completion fluids.

APPLICATIONS
A B DEFOAMER is a wide-application product that reduces the foaming tendencies of water-base drilling fluids. It
is compatible with freshwater mud, brackish water mud, seawater mud, saturated salt mud, brine completion systems
and all common mud additives.
A B DEFOAMER is easy to mix, works quickly, is effective in low concentrations and is a more persistent
Defoamer than alternative products.
Normal treatments of A B DEFOAMER range from 0.10 to 0.20 lb/bbl (0.29 to 0.58 kg/m³). The use of A B
DEFOAMER is recommended for foam prevention when making
periodic treatments with organic materials such as lignosulfonate, lignite and tannin-based additives. When
preparing brines, a pretreatment of 0.25 lb/bbl (0.72 kg/m3)
of Defoamer is effective in preventing foaming.
A B DEFOAMER should be added to the mud pits in a location that allows the product to be incorporated into the
entire circulating mud system. A B DEFOAMER should not be diluted, but should be added directly to the drilling
fluid system by either a drip method from a 5-gal container or as a shock by broadcasting over the surface of the pit.
Dilution significantly reduces the effectiveness of the product.
ADVANTAGES
· Easy to mix. Works quickly and is effective at low concentrations in a wide range of systems.
A persistent Defoamer.
Aids in the removal of dissolved oxygen.
Controls foaming in fluids viscosified with polymers.
Helps stabilize pump pressure by removing trapped air and gas.
Low-toxicity product and environmentally acceptable at the recommended concentrations.
LIMITATIONS
Not effective in mud that have excessive gel strengths.
