Optimize scale management through comprehensive inhibitor chemistries and deployment techniques.
A major operator in the Danish sector of the North Sea was using three different scale inhibitor formulations across five offshore platforms. The chemicals were continuously injected topside to mitigate the risk of carbonate scale; additional amounts were added during reinjection of spent triazine-based H2S scavenger, which increases the risk of calcium carbonate scaling. Discharging the spent scavenger into the sea was not advisable because of the consequent environmental impact. The operator wanted a more cost-effective and simplified scale management strategy.
