In the diluted polymer injection scheme, conventional valves often generate high shear during injection. The high shear rate results in reduced sweep efficiency in the reservoir, unless compensated by either 1) using a more expensive and shear stable polymer to reduce degradation, or 2) increasing the polymer concentration to compensate for the viscosity loss.
Typhonix Polymer Flooding Valve can be used to replace the standard valves, to reduce the shear. Results from the prototype test in a diluted application, shows that the standard valve resulted in 35% to 60% viscosity degradation. Typhonix Polymer Flooding Valve resulted in 1% to 10% viscosity degradation under the same conditions.
For some applications, using Typhonix Polymer Flooding Valve instead of a standard valve can reduce OPEX with $500*)
per well, every day. This is because a 25% more expensive polymer is needed to compensate for the high shear of the standard valve.
