Well Drilling Foam
Bilden WELL DRILLING FOAM is a water soluble, biodegradable foaming agent. This material is designed exclusively for mineral and water well drilling. This foam has the ability to foam in fresh,brackish or salty waters.
WELL DRILLING FOAM is completely biodegradable and will not contaminate streams or ground water.
WELL DRILLING FOAM presents no disposal problems and is not harmful to personnel, vegetation
Drilling foam is especially suitable for drilling large holes in formations that are prone to lost circulation. Foam is generated at the surface by mixing the air from the compressors with a foaming solution from the mist pump. The consistency of this “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.
