A customer on the North Slope of Alaska was
experiencing foam in its reservoir drill-in fluid.
Treatment was possible with conventional
defoamers, but product usage was deemed
excessive. M-I SWACO proposed using
DEFOAM EXTRA high-performance defoamer, a
silicone-base defoamer proven to be highly effective
at very low concentrations. Laboratory testing
confirmed that DEFOAM EXTRA defoamer would
outperform the conventional products to both treat
and prevent foaming.
