... chemistries provide an alternative approach to acid chemistries to mitigate the formation of calcium naphthenates with lower treatment rates, non-corrosive properties, and pH independence. This contribution presents the evaluation of three non-acid chemistries as calcium naphthenate inhibitors using a two...

... of this polyurethane chemistry is more than six hours when immersed in aqueous fluids at 80°C (176°F) (i.e. water or 3% potassium chloride). The elastomer can be compressed over 70% during its service-life providing a stable set of mechanical properties during use. The elastomer beings to fracture within two days...

..., highly reliable vulcanisation chemistry allows for a stable latency time for application, with vulcanisation temperatures reduced to 50°C. This allows for rapid hand application and simultaneous vulcanisation on subsea trees, valves, manifolds, etc. The material is self-agglomerating, merging under...
