In this keynote paper (SPE 218716) the focus will be on case study North Sea fields looking into the control of the scale risk within the topside process, water injector wells and the evolving scale risk within the production wells. The lessons learned from this study are that changes in scaling potential within a PWRI system require to be carefully assessed prior to the onset of PWRI. While control of scale issues within the topside process and water injector wells has proved easy to predict and manage, the extended scale risk and challenges of tracking squeeze treatment performance need to be considered as this may present a significantly higher operation cost for effective scale management.
