Petra Soltex

PETRA SOLTEX (ASPHATEX SUPREME) is a high-performance Sulphonated Asphalt specially developed for drilling fluid applications. It improves wellbore stability, reduces fluid loss, and enhances lubrication in challenging drilling conditions.

Designed for oil & gas, geothermal, and mining drilling operations, PETRA SOLTEX performs effectively in high-temperature, high-pressure, and highly deviated wells.

What is Sulphonated Asphalt?

Sulphonated Asphalt is a drilling fluid additive used to control shale swelling, improve borehole stability, reduce torque & drag, and minimize fluid loss in water-based drilling fluids.

Key Features:

• Improves wellbore stability
• Reduces API & HTHP fluid loss
• Enhances lubrication properties
• Effective in HPHT drilling conditions
• Compatible with various drilling fluid systems
• Environmentally acceptable drilling additive

Applications of PETRA SOLTEX

• Shale Stabilization – Controls shale swelling and improves borehole integrity.
• Fluid Loss Control – Reduces API and HTHP fluid loss during drilling operations.
• Lubrication Enhancement – Minimizes torque, drag, and friction in drilling systems.
• HPHT Drilling Operations – Performs effectively in high-temperature and high-pressure wells.
• Oil & Gas / Geothermal Drilling – Suitable for demanding drilling environments and complex formations.
