Foam drilling is a method of underbalanced drilling especially suitable for large diameter holes in formations that are prone to lost circulation. Foam is generated at the surface by mixing the air from the compressors with a foamer/make-up water solution from the mist pump. The consistency of this “foam fluid” is much like shaving cream with an interlocking bubble structure of encapsulated air providing a lifting capacity superior to that to any drilling fluid.


The adjustment of the Foam Quality (gas/fluid ratio) in conjunction with a back pressure valve allows the operator to produce a bottom hole pressure equivalent to a circulating fluid weight in the range 0.2 to 0.8 S.G.
