Product Description


Sulfonated Asphalt is   a sodium asphalt sulfonate made water soluble by a unique sulfonation process. It is a versatile, total mud conditioner that   stabilizes shale formations, significantly increases lubricity, and lowers   HTHP water loss. Sulfonated Asphalt enhances filter cake properties in both   oil- and water-based muds. Sulfonated Asphalt is the best equivalent of Soltex (CHEVRON).




Sulfonated Asphalt can be used in most water-based and   all oil-based and synthetic muds




Controlled water and oil solubility to effect best   chemical and physical performance

Minimizes damage to productive formations

Reacts with shale to prevent or stop sloughing and   swelling

Significantly increases lubricity; either alone or   synergistically with small amounts of oils and synthetics

Environmentally acceptable -is used on land and   offshore

Extremely temperature stable - does not have the   softening point typically associated with unreacted asphaltic additives

Inhibits dispersion of drilled solids

Minimal and easily distinguishable fluorescence - does   not hamper well logging or core analysis

Will not leave oil slick, sheen or rainbow on water at   offshore locations

No emulsifiers needed to ensure proper mixing


Technical Data





Black free flowing powder











     Recommended Treatment

Conventional hopper when chlorides   do not exceed 60,000 ppm. When adding to high salinity systems, Sulfonated   Asphalt with fresh water by adding through chemical barrel may give best   results.
