Key Words: Sodium Asphalt Sulfonate; Asphalt Sulfonate.
CAS No.: 68201-32-1
Properties:
Sodium Asphalt Sulfonate is partially water soluble and water dispersible.
Sodium Asphalt Sulfonate acts to aid in stabilizing shale sections, controlling solids dispersion and improving wall cake characteristics. Unlike some other blending gilsonite,
Sodium Asphalt Sulfonate is highly sulfonated by unique process which leads to partially oil soluble as well. This property gives more excellent emulsifying characteristic.
Sodium Asphalt Sulfonate is also highly resistant to temperature.
Sodium Asphalt Sulfonate stabilizes shale formation by inhibiting disintegration of the shale both chemically and physically.
Sodium Asphalt Sulfonate inhibits the dispersion of drilling cuttings, controls high temperature high pressure (HTHP) filtration.
Sodium Asphalt Sulfonate reduces torque and drag, prolongs the life of the bit, improves filter cake quality and enhances well productivity.
Sodium Asphalt Sulfonate also acts as an emulsifier of diesel oil.

Usages:
Sodium Asphalt Sulfonate can emulsify fresh water or sea water with oil, depress the solid expansion of drill chips, controls HTHP FL, produces thin and tenacious mud cakes, and helps maintain low shearing rate under HTHP,
Sodium Asphalt Sulfonate can clean and stabilizes well holes that have a great deal of collapsing shales.
