Sulfonated asphalt, a drilling mud additive used for shale stabilization and shale conditioning in the Oil & Gas Industry is now available.

Sulphonated asphalt (also spelled sulfonated asphalt) is one of the most popular compounds manufactured from sodium asphalt sulphonate for use as a Shale Stabilizer and Shale Conditioner in the Oil & Gas Industry.

In addition to shale stabilization, this versatile “mud” conditioner that was engineered to work well with all water-based and oil-based mud systems, also affords the following important benefits to well operators:
  • It controls HTHP (high temperature, high pressure) fluid loss
  • It’s not biodegradable
  • It’s highly temperature stable
  • It stabilizes the hole formation
  • It contributes to the stability of the drilling fluids
  • It’s 80-90% soluble in water.  The insoluble portion remains in the drilling mud and “plasters” the formation surface providing improved filter cake properties.
  • It improves lubricity and therefore reduces torque and drag
  • It contributes to the stability of the drilling fluids
  • It aids in the emulsification of oil
  • It improves the performance of the drilling mud by controlling its chemical and physical properties
  • It inhibits the disintegration and dispersion of solid drilled cuttings
  • It controls high temperature water loss which prevents further formation/shale hydration and sloughing.
  • It is highly effective in dispersed and non-dispersed polymer, PHPA and other systems.
  • It controls viscosity
  • It helps seal micro fractures
  • It prevents drill bit and down hole assembly bailing
  • It inhibits corrosion
  • It enhances well productivity


Application: For shale control, fluid loss improving, Torque and Drag Reduction ,Inhibition of Swelling clays  of all water mud’s.

COMMON NAME – Sulphonated Asphalt/ Shale Stabilizer /HTHP Fluid Loss Controller

Usage: it is a Free flowing Powder and can be added Directly to the Mud System through the Mixing Hopper with a good Agitation system . Typical concentration range from  3-7 lb/bbl (8.55 Kg/m3 -20 Kg/m3) for shale Stabilization .Dosage may be Increased to 10 lb/bbl if required .

Packaging: Material is packed in 25kg or 50 Lbs (22.68 Kg) sacks.

Safety and Handling: Material must be handled as an Industrial chemical, wearing protective equipment and observing the precautions as mentioned in the MSDS.
