The paper "The Development of a Low-Shear Valve Suitable for Polymer Flooding" has been published in SPE Journal.
This paper presents the development of a novel valve technology suitable for polymer flooding. The performance of the new valve technology is demonstrated through small- and large-scale prototype tests. At very-shear-sensitive test conditions, it is demonstrated that polymer degradation of the new valve is less than 10% at 40- to 45-bar pressure drop, compared with 60 to 80% for a standard valve.
