dvr 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.

DOSE : According to application below deose are recomended –

Application Dose
Stabilize shale formations 3.0 to 6.0 ppb (9.0 to 17.0 kg/m3)
Impart significant lubricity 1.0 to 3.0 ppb (3.0 to 9.0 kg/m3)
Reduce torque and drag 1.0 to 3.0 ppb (3.0 to 9.0 kg/m3)
Control HTHP fluid loss in water base
& oil base Mud
2.0 to 6.0 ppb (6.0 to 17.0 kg/m3)
Produce strong compressible wall cakes 2.0 to 4.0 ppb (6.0 to 11.0 kg/m3)
Emulsify oil into water based mud systems 0.5 to 3.0 ppb (2.0 to 9.0 kg/m3)
Control shear strengths and increase
thermal stability
2.0 to 6.0 ppb (6.0 to 17.0 kg/m3)
General hole conditioning 2.0 to 6.0 ppb (6.0 to 17.0 kg/m3)


  • 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.
