Sulphonated Asphalt - Color: Dark/grey Free Flowing Powder

Here are the top 10 standout features of Sulphonated Asphalt as a drilling fluid additive:
Shale Stabilization: Effectively prevents shale hydration, swelling, and sloughing by sealing micro-fractures.
High-Temperature Stability: Maintains chemical integrity and performance under extreme downhole temperatures (200a C+ / 400a F+ ).
Fluid Loss Reduction: Significantly lowers high-temperature, high-pressure (HTHP) fluid loss into permeable formations.
Torque & Drag Reduction: Acts as a powerful solid lubricant, reducing friction between the drill string and the wellbore.
Casing Protection: Deposits a thin, tough, and flexible filter cake that protects the borehole wall and prevents differential sticking.
Versatile Compatibility: Blends seamlessly into both water-based and oil-based mud (OBM) drilling systems.
Emulsification Booster: Enhances the stability of oil-in-water emulsions in water-based drilling fluids.
Cost-Effective Extender: Enhances the performance of other mud additives, reducing overall mud maintenance costs.
Minimal Viscosity Impact: Provides excellent filtration control without causing unwanted, excessive spikes in mud viscosity.
Shear-Thinning Support: Helps maintain optimal rheological properties for efficient cuttings transport to the surface.

PETRA SOLTEX (ASPHATEX SUPREME) is a high-performance sulphonated
asphalt additive designed to improve drilling fluid performance in challenging
drilling conditions.
It enhances wellbore stability, reduces fluid loss, and
provides excellent lubrication and shale control.
This product is widely used in oil & gas, geothermal, and mining drilling
operations where high temperature, pressure, and reactive shale formations are
encountered.
