In the process of fracturing and acidizing of oil wells production operations, working fluid flows through the reservoir at high speed, forming the emulsion with the crude oil. And then the reservoir’s permeability declined. This matter seriously affects the well fluid flowback velocity and the oil well production.  

JKN-DEM is used in acid fluids. It is a good emulsion-preventing agent to be used to prevent emulsions caused by acid mixing with the produced oil. The flowback rate can be also improved efficiently.
