... extraction are used. Depending on the type of emulsion, two independent sensors are used in the oil pipeline, one of which measures in a direct emulsion, the other in an inverse emulsion. Tests of the described water cut meter on flow loops in the Russian Federation and in the Netherlands, as well...

.... Historically, the technical column interval has been drilled using generic OBM using local crude oil. However, such fluids carried significant health and safety risks associated with low flashpoints. Invert emulsion fluids, based on local crude oil as the continuous phase, are characterized by flashpoints...

... Summary The separation of water-oil emulsions in the fields is considered to be a significant part of the costs associated with the production and transportation of the produced fluid. This is mainly connected to the use of chemical reagents (demulsifiers), which accelerate the process...

... on a double-beam NIR spectrometer have been carried out. Water-oil emulsions with different moisture contents have been used as test specimen. Optimal ranges of wavelengths to analyze the emulsion composition at different thicknesses of a translucent mixture have been determined. It has been shown...
