Abstract

We report in this paper how we degrade polymers in solution and measure the consequent viscosity loss in a few minutes in a microfluidic device. This study is of importance for oil recovery processes where polymers are used as viscosifying agents. Thanks to a fabrication technology resistant to high pressures and a specific chip design integrating a constriction, a reservoir and a viscosimeter, we provide a tool for the rapid exploration of viscosity loss versus deformation rates imposed to the polymer solution, using small amounts of samples.
