ABSTRACT:
A process for reducing scale formation in off-shore production platforms where sea water is used as a water-flooding medium. During production, sea water and connate water interact to make scale forming precipitates. Said precipitates fall out in an oil/water separator. Subsequently, additional sea water is injected as the separated aqueous phase leaves said separator thereby causing additional precipitates to form. Via this method, decreased amounts of scale preventing inhibitors are required.
