  • Provides stable and cost-effective emulsion
  • Allows adjustable concentrations to balance emulsion stability with increased ROP

OptiPlus II emulsifier is effective with NaCl, CaCl2 or NewPhase™ internal phases. It should be used in an alkaline environment. An excess of Ca(OH)2 (lime) should always be present in the fluid.

Treatment Recommendation

OptiPlus II emulsifier concentrations should be engineered to the specific fluid design, but a typical range is 2-8 lb/bbl (0.26-1.04 gal/bbl). The emulsifier can be added through the hopper or directly into the pits, providing agitation is sufficient.
