Application & Features

Sodium Asphalt Sulfonate is partially water soluble and water dispersible. It acts to aid in stabilizing shale sections, controlling solids dispersion and improving wall cake characteristics. Unlike some other blending gilsonite, it is highly sulfonated by unique process which leads to partially oil soluble as well. This property gives more excellent emulsifying characteristic. It is also highly resistant to temperature.

Sodium Asphalt Sulfonate stabilizes shale formation by inhibiting disintegration of the shale both chemically and physically. It inhibits the dispersion of drilling cuttings, controls high temperature high pressure (HTHP) filtration. It reduces torque and drag, prolongs the life of the bit, improves filter cake quality and enhances well productivity. It also acts as an emulsifier of diesel oil.
