Product Description
OptiVert™ emulsifier is a fatty acid derived product which provides a stable water-in-oil emulsion. It is designed as an alternative to OptiMul™ II for Newpark’s OptiDrill™ or OptiPhase™ diesel- or mineral oil-based drilling fluid.
Benefits
- Provides a stable emulsion in a cost-effective manner
- Allows adjustable concentrations to balance emulsion stability with increased ROP
- Imparts oil-wetting characteristics
- Performs effectively in the presence of contaminants
Application
OptiVert emulsifier can be added when first preparing the OptiDrill system or as a treating agent during drilling operations. The product is effective with NaCl, CaCl2 and 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
OptiVert concentrations should be engineered for the specific fluid design, but a typical range is 2-8 lb/bbl (0.27-1.09 gal/bbl). The need for additional treatments is indicated by the presence of water in the HPHT filtrate and/or low emulsion strength as measured by an electrical stability meter. The emulsifier can be added through the hopper or directly into the pits, providing agitation is sufficient.
