Enhanced Oil Recovery Techniques have been used to successfully extract crude oil from oil fields. According to theEnergy Department's Office of Fossil Energy, EOR techniques have allowed "30 to 60 percent, or more, of the reservoir's original oil in place."
There are many types of EOR techniques including polymer flooding. This advanced technique is the process of injecting viscous fluid that assists in crude oil displacement. In the field of fluid mechanics, the process of displacement refers to the immersion of an object in a fluid. Simply put, the measurement of the total volume of fluid inserted and required to take the place of the original object is displacement. Tying the fluid mechanics method with EOR, different types of polymers are used in the polymer flooding process.

Using Extensional Viscosity for Material Performance
Extensional or elongational viscosity is ideal when it comes to studying the complex properties of fluids used in many industrial applications. e-VROC Viscometer enables successful apparent extensional viscosity measurements through the process of monitoring the sample flow through a microfluidic contraction where the pressure upstream and downstream of the contraction can depict the changes in flow.
