Mutual solvents are typically additives used in oil field and well applications that are soluble in oil, water and acid-based treatment fluids. Typically, a mutual solvent is soluble in both aqueous and oleaginous fluids. Depending upon the solvent, the solvent may be substantially or completely soluble in each phase. A solvent is used to:

  • Prevent surfactant and corrosion-inhibitor adsorption onto formation minerals
  • Prevent the formation of emulsions
  • Disperse additives that have limited solubility in treatment-fluid blends

CRISTOL Mutual Solvent  is a unique blend of solvents containing oil and water soluble alcohols that provide the combined benefits of hydrocarbon deposit removal and water wetting characteristics. CRISTOL Mutual Solvent Chemical may break and / or prevent emulsion and water blocks. Treatments will temporarily leave the contacted formation in a water-wet state, thereby increasing the relative permeability of the formation to oil, which may increase production.


  • Reduces the adsorption of surfactants onto formation minerals
  • Can aid in the removal of oil deposits from scale deposits and formation minerals when used in treatment fluids
  • Can help disperse treatment-fluid additives within a treatment-fluid blend, thereby helping prevent separation of those additives from the blend
  • Can be used in most types of fluids; it is mutually soluble in both aqueous and hydrocarbon fluids
