Stability and chemical demulsification of water-in-crude oil emulsions (chemical method)

The formation of water-in-crude oil (W/O) emulsion can be encountered at many stages during drilling, producing, transporting and processing of crude oils. A good understanding of petroleum emulsions is necessary for the intention to control and enhance the processes in all these stages. In this stu...
