OS FOAMADRIL PLUS - Drilling Foamer Premium Grade
Foam fluids are used in air drilling applications when extra carrying capacity is required or to reduce the necessary air volume. Air and/or foam drilling has many applications including drilling in loss circulation zones, drilling through unconsolidated formations and water-well drilling. Foams can be used in conventional circulation mode or with reverse circulation.
Care is necessary when choosing foamers to determine the quality of the make-up water.
OS FOAMADRIL PLUS is a highly active surfactant specifically designed to provide a broad spectrum foamer that produces a stiff foam suitable for drilling activities. OS FOAMADRIL PLUS performs well in the presence of oil and metal cations such as calcium.

OS FOAMADRIL PLUS is a wide spectrum foamer that can be used in both fresh water and brines. Required dose levels will depend upon the hardness of the water, the chloride levels and the amount of contaminants encountered (e.g. oil) and the stiffness of the foam required. The optimum levels for each application should be determined in the lab but the following will serve as a guide. For fresh water drilling, the treatment rate should be about 0.25% of OS FOAMADRIL PLUS by weight. For sea water drilling, the treatment rate should be about 0.5% to 1% of OS FOAMADRIL PLUS by weight. For wells that are prone to flooding, the foam quality should be maintained by injecting OS FOAMADRIL PLUS into the air line.
OS FOAMADRIL PLUS is packaged in 220 kg drums.
