RXSOL Tex Additive (Mud Conditioner)
RXSOL Tex Additive 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. Rxsol Tex Additive enhances filter cake properties in both oil-based and water-based muds. Due to unique chemistry of Rxsol Tex Additive has delivered extraordinary results in both water-based and oil-based muds.
Advantages
- 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 un-reacted 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.
- Stable in Drilling Applications to 500 °F.

Use for stablize shale formations, significantly increases lubricity, and lowers HTHP water loss.
Mixing : Conventional hopper when chlorides do not exceed 60,000 ppm. When adding to high salinity systems, pre-wetting Rxsol Tex Additive with fresh water by adding through chemical barrel may give best results.
