Encapsulated Polymer Technology Overcomes Shear Degradation and Injectivity Loss Offshore

Polymer flooding in offshore environments faces the challenge of high shear forces encountered in subsea injection systems. These extreme shear conditions can induce mechanical degradation of polymer chains. In response to this limitation, encapsulated polymer technology has been developed to mitigate shear degradation and optimize polymer performance in offshore applications. This approach involves encapsulating polymer molecules within a protective shell that shields them from degradation during injection while enabling controlled release within the reservoir.
