oa The Technical Performance and Interpretation of Results from a Large Scale Na-Silicate Gel Treatment of a Production Well on the Gullfaks Field

The development program for processes to reduce watercut during production of the lower Brent reservoir unit of the Gullfaks field culminated by a large scale injection of alkaline Na-silicate gel in a lower Brent production well during summer 1993. The operation was prepared and designed through an extensive laboratoiy program as well as small scale onshore field tests.
