WebFoam property tests, consisting of a foam expansion ratio test and a water drainage test, were conducted to classify foams. Compressed-air-generated foams tended to have low expansion ratios, from 10 to 19, with high water drainage. Blower-air-generated foams had higher foam expansion ratios, from 30 to 60, with lower water drainage. WebFoam property is usually measured by its viscosity. Polymers are used in foam drilling fluids for a variety of reasons. They may be used as viscosifying agents to improve foam carrying capacity, as lubricity agents to decrease the fluid friction factor, or to chemically stabilize the wellbore, particularly when shales and clays are present. ...
